1 MUSTANG DISTRICT

1.1 Introduction

1.1.1 Location

Mustang District is located in Dhawalagiri Zone; Western Development Region bordering with Tibet

at its north. The district, with Jomsom as it's headquarter covers an area of 3,573 km2. According to

2011 census, it has a population of 13,799 with growth rate of -0.82 %. The district straddles the

Himalayas and extends northward onto the Tibetan plateau. It is a hilly district with altitudes ranging

from around 2,000 to over 8,000 metres. Most of the district has rocky landscape and is virtually a

mountain desert, its harsh grandeur broken only by small oases, where villages have grown up

around a water source. The district is very famous for trekking. Out of several trekking routes,

trekking to Lomanthang, Annapurna circuit and Muktinath are few to mention. One of the

uniqueness of the Mustang District is that it lies at the north of Himalaya and hence its climatic

condition is very different from other districts. The most notable consequence is that the rainfall in

the whole district is very low. As per DHM the total rainfall in Mustang in 2008 is 312 mm. This is

about 5 times less than the national average.

The location map of the district is given in Fig. 1.

Fig.1: Location Map

1.1.1 Road Network

The total road network in Mustang District is 207 km. The main road of the district; from Pairothapla-

Jomsom was constructed by the Nepal Army. At present this road is in the form of motorable track.

Condition of the above road and other roads in the district is very poor. It is to be noted that

Pairothapla-Jomsom-Muktinath road section falls within the north-south road corridor (highway)

linking India and China and is classified as future national highway.

There are only three strategic roads in the district. Their details are given in Table 1.

1.2 District Master Plan

The strategic roads in the Mustang District fall under the jurisdiction of Pokhara Division of DoR.

Pokhara as well as other 24 divisions of DoR are required to prepare Annual Road Maintenance

Programs (ARMP). GoN/DoR allocates yearly budget to a division only after approval of the plan. The

basic objective of the ARMP is to identify and prioritise and plan the maintenance of the roads in

order to keep them in adequate condition by optimum utilisation of available funds. This will help the

Roads Board and DoR to achieve a need based allocation of scarce resources towards the

maintenance & upkeep of these national assets- the roads.

It is to be noted that the Pairothapla-Jomsong and Jomsong-Ghoktang road sections which lie in

Mustang District are the end sections of one of the north-south road corridor identified by DoR.

Hence GoN is giving high priority for construction of these road sections. As informed by the technical

staffs of Pokhara Division, GoN plans to start the North-South road corridor within 2-3 years.

Similarly, DoR is also planning to upgrade Kagbeni-Muktinath Road.

1.3 Sector Budgeting and Staff

1.3.1 Budgeting

The annual budget of the Pokhara Division for the Financial Years 2010/11 and 2011/12 is

666,668,000 rupees and 687,768,000 rupees respectively. Out of the total, the budget provisioned

for Baglung-Beni-Jomsom Road in FYs 2011/12 and 2012/13 is 4,140, rupees and 64,700 rupees

respectively and is meant for construction of small bridges, cross drainage structures, routine

maintenance and emergency maintenance.

The budget details of Pokhara Division are given in Annex A.

1.3.2 Staff

Pokhara Division Office is headed by a senior divisional engineer (gazetted 2nd

class officer). The other

staffs in the division are: engineers (7 nos.), sub-engineers (6 nos.), account officer (1 no.), section

officer (1 no.) and other support staffs (19 nos.).

The list of Staff working in the division is presented in Annex B.

1.4 Sector Trends and Issues

Pokhara Division is one of the 25 divisions of DoR and covers several districts including Mustang.

Although the main task of the division is to maintain the roads (routine, periodic, emergency,

recurrent etc.) it also executes small to medium road and bridge projects.

1.4.1 Trends

The current trend of the DoR is as follows:

Planning

Planning of works is done by the respective divisions. The division is required to prepare annual road

maintenance plan (ARMP) for each year. After approval of the plan by Ministry/DoR, yearly budget is

provided to divisions. Without ARMP, the division will not be able to receive the yearly budget.

Design

Design works of roads and bridges, in general, are carried out by local consultants. For big projects,

(especially WB, ADB funded) DoR hires foreign consultants.

Construction

Almost all the construction and maintenance works of roads and bridges are done by using

local/national contractors. The present trend in construction has shifted from manual to machines.


7

Construction equipments such as excavator, paver, dozer, roller etc. are being used more frequently

at present.

Although Pokhara Division is mainly responsible for the maintenance of roads, it is also handling

medium scale construction works. For example it is executing small bridges along Maldhunga-Beni

section. Similarly, it is rehabilitating/upgrading several roads under its jurisdiction.

Supervision of Works

1. For small works, division staff carryout supervision works;

2. For medium scale works the division hires local consultants also;

3. For large contracts, especially for donor funded contracts, both national and foreign consultants

are hired.

Monitoring

Monitoring is done on the following aspects:

1. Programme

2. Cost

3. Quality

4. Progress

1.4.2 Issues

General

1. Approved Budget funds are not released on time

2. Programmes are not approved on time

3. Very low bids are submitted by the contractors

4. Contractors receive mobilization advance but do not execute the work on time.

Specific

1. The number of projects in budget head 337107 (construction of district roads) is high. The

present work force is not sufficient to execute these works. Therefore, these projects should be

handed over to District Development Committees (DDCs); otherwise quality control work cannot

be maintained.

2. To keep the strategic road networks in good condition, sufficient budget is required for specific

maintenance and road rehabilitation too. The recurrent works at urban area should be executed

by forced account method.

3. Tendering and contract agreement process of Road Sector Development Project (RSDP) of DoR

for periodic reseal works is very slow resulting in time and cost overruns.

1.5 Past Extremes in the District

The past extreme events in the district is presented in Annex C

1.6 Linkages to Other Sectors

The DoR at present is co-operating with the following agencies in the district:


8

DDC, Municipalities, DoLIDAR, DoI, DWSS, DWIDP, NT, NEA, Department of Transport (DoT)

1.7 Priority infrastructure in Mustang District

1.7.1 Prioritization process

The key criteria for prioritisation for infrastructure to be included in this project are:

Infrastructure of national strategic importance

Infrastructure of district strategic importance

Infrastructure that has been impacted by past extreme events

Infrastructure located in areas prone to past extreme events

At least one planned new infrastructure

The consultant, in consultation with the division chief, prepared a final list of the priority

infrastructure assets of the district to be included in the baseline study for Mustang following the

above criteria. The priority list is given in the table below.

Table 2: Prioritized Assets

2 MUSTANG: ASSET BASEL INE

All the above assets lie on the Pairothapla-Jomsong section of Sunauli-Pokhara-Beni-Jomsom-

Ghoktan Road, which is identified by GoN/DoR as an important north-south road corridor. The total

length of the road corridor is 473 km and it can be divided into following sections:

Siddhartha Highway (Sunauli-Pokhara): This road section was constructed in mid seventies with the

assistance of Indian Government. Its total length is 181 km. The road is blacktopped and its condition

is good.

ID Name Infrastructure

type

Reason/s for inclusion

1 Road section

damaged by

Podkyu Khola at

Marpha (km 72).

Road In July 2013 there was extensive rain at/ around Marpha

area. The heavy rain caused flooding in Podkyu Khola. The

flood washed away about 250m long road sections. Such

incident will be more with CC and should be properly

studied.

2 Road section

eroded by

Kaligandaki River

at Tukuche (km

65).

Road About 1.5 kilometer of road is located very near to

Kaligandaki River. Due to poor geology, the river is eroding

the road and at one location it has washed away 40m long

section. This issue is very important as substantial road

length falls under this threat. With CC this threat will

aggravate and hence is included for this study.

3 Road damaged

by landslides

near Lete Khola

(km 42)

Road The road sections at both sides of Lete Khola are

frequently blocked due to landslides. Because of weak

geology along major sections, blockage of traffic by

landslides is common. Such incident will more frequent

after CC if not addressed properly.


9

Pokhara- Baglung-Beni: The road section between Pokhara and Baglung was constructed with the

assistance of Chinese Government. Its total length is 77 km and was completed in late eighties. The

last road section Baglung (Maldhunga)-Beni was constructed by DoR and was completed few years

ago only. The whole road section from Pokhara to Beni is black topped.

Beni-Jomsom: This section of the road was constructed by Nepal Army and is still in the form of

motorable track. It is an earthen road and its total length is 80km. Out of the total length, 21 km long

section lies in Myagdi District and the remaining 59 kilometer in Mustang District. Few bridges across

Kaligandaki River and other small streams are already constructed along this section.

Jomsom-Ghoktan: This is the last section of the road corridor and is still not fully trafficable. Road

section from Josmsom to Kagbeni (about 10km) was constructed by DDC/local bodies and is operable

at present. Kagbeni -Jhaite Road section which is 38.8 km long was recently upgraded by

DDC/DoLIDAR with assistance of ADB, DFID, GoN and is motorable at present. According to local

people special trucks can reach to Lomathang which is main center of Upper Mustang. The road

length from Jomsom to Lomathang is estimated to be 85 km. The remaining road section from

Lomathang to Ghoktan is still not motorable.

2.1 Asset 1: Washed away Road Section at Marpha (km 72)

2.1.1 Asset Description

In July 2013 there was extensive rain at/ around Marpha area. The heavy rain caused flooding in

Podkyu Khola and washed away about 250 long road sections at both sides of the khola. In the mean

time the flood deposited large amount of debris at/around the road side (see photo and sketch). Due

to such incident the vehicles are unable to cross the Khola from the original road track. At present

they cross the Khola from 400 m downstream. DoR is planning to construct temporary motorable

crossing at the washed away location by constructing vented causeway.

Photo: Overall view of road damage and debris deposition. According to the local people, the Khola

washed away substantial road length at both sides due to heavy flood in July 2013. The flood was

caused by continuous rain for three days, which is a rare incident for that area

11

Watershed Context

Podkyu Khola is a small stream. The length of the river from the origin to the road crossing (or

Kaligandaki River) is about 6 km and the watershed area is 37 sq.km. In general it has small discharge.

The flash flood which happened recently is an exceptional case. The land use map of the Podkyu

Khola is in Fig.3.

.

Fig 4: Land use map of Podkyu Watershed.

As seen from on map, most of the watershed of the stream is barren land, bushes, grass and forest

whereas the area under cultivation area is very few. The detail land use data is given in table 3

Asset location

The asset is located at km 72 from Beni along Beni-Jomsom Road. It is at a distance of 400m

upstream from the confluence of Podkyu Khola with the Kaligandaki River. The area where the asset

is located is the foothill. In addition to threat by Khola, the adjacent road sections are also vulnerable

to erosion by Kaligandaki River.

The whole area where the asset is located is barren land with little vegetations. The hill at the right

side of the Khola consists of loose soils and is easily erodible by rainfall. Although the left side

(towards Jomsom), the upper part of the hill is rocky and stable the lower portion from where the

road passes is unstable.

Asset condition

About 250 m long motorable track was completely washed away by debris. The condition of the

adjacent road sections (at both sides of the khola) is also poor.

Asset design

The road is in the form of motorable track and has very poor geometry. GoN/DoR is planning to

upgrade the whole road to a national highway.

Past extreme events and impacts

Due to intensive raining for 3 days, there was a high flood in the Podkyu Khola in August 2013. The

flood washed away the road as well as deposited large amount of debris on a very large area (see

above sketch).

The past extreme events in the district are given in Annex C.

Past adaptation responses

There was not any structure before the damage. DoR is planning to construct a temporary crossing

structure of vented causeway before 2014 monsoon.

Design appropriateness

As mentioned earlier, the road is a motrable track. Detail design of road and allied structures is still

not carried out.

2.1.2 Adaptation audit

DoR has not constructed any protection structure after the damage. Hence the vehicles at present

cross the Khola from 500 m downstream of the existing crossing.

DoR is planning to construct ventage causeway as a temporary measure(until the road is upgraded to

national highway). The design of the causeway is provided in a sketch below. The estimate cost of the

vented causeway is 3.0 million rupees.


13

Fig 5:Sketch showing layout of adaptation measures at Marpha

The structure as proposed by DoR is temporary. It can withstand normal flood but it is very

vulnerable to intensive rain.

2.2 Asset 2: Road Damage by Kaligandaki River at Tukuche



14

About 40m long section at km 65 of Beni-Jomsom Road (motorable track) was completely washed

away in 2010 after 2 year years of its construction. After the incident, DoR realigned the road from

the hill side (at about 10m away from the previous road alignment). There is not any damage to

realigned road section. Photograph and sketch showing eroded section of the road is presented

below.

Photo: The Kaligandaki River washed away about 40m long section of road at this location in July

2010. After the incident the road was realigned at about 10m towards hill side. Two persons can be

seen walking along the realigned road.


15

Fig 6: Layout of damaged road at Tukuche

Watershed context

The asset lies inside the watershed of Kaligandaki River. The watershed area of Kaligandaki River at

the asset location is about 3200 sq km. The Kaligandaki watershed receives very small amount of

rainfall and hence the river discharge at this area is not very dependant of rainfall. However, the

river discharge at this area is highly sensitive to snow melting. As a consequence the river discharge

increases during April-June when snow melting will be high. Beside the threat by the river, the asset

is vulnerable to landslide due erodible soils and little vegetations.

Asset location

The asset is located at about km 65 of Beni-Jomsom Road. At this area about 2 km of road lies very

near to Kaligandaki River. Due to poor geology, the right bank of the river from where the road

passes is being eroded by the river and at some locations; they are highly vulnerable to washing

away.

Asset condition

The condition of road at this area is very poor as not a single protection and drainage structures are

constructed. Its condition will improve only after its upgradation when sufficient retaining and

drainage structures will be provided (or when it will be upgraded to national highway).


16

Asset design

The road is in the form of motorable track and has very poor geometry. GoN/DoR is planning to

upgrade the whole road as national highway.


In July 2010, 40m long section of the road was eroded by the Kaligandaki River. The other past

extreme events in the district is presented in Annex C.


DoR has relocated the road through 10m hill side from the damaged location. There has not been

damage to realigned road section. This indicates that the road should be located further from the

river bank.


The road geometry is poor. The road lacks minimum drainage and retaining structures.


Adaptation location

After the washing away of the road, the road is realigned at about 10m away towards the hill side.

Adaptation condition

The condition of realigned road section is satisfactory.

Threat description

There is a continued threat of river erosion at/around the assets due to proximity of the road

alignment with the Kaligandaki River and poor geology of the area.


Same as in section in 2.2.1.

Adaptation design

Same as in section in 2.2.1.

Adaptation success

The adaptation measure (realignment of road through hill slope) is generally successful but the road

section could be more stable if adequate retaining, drainage and river protection works are provided.

2.3 Asset 3: Road Damage by Lanslides at Lete


About 150 m long road sections at both sides of the Lete Bridge are frequently blocked by landslides

during monsoon period. In monsoon 2013, there were several landslides at his section blocking traffic

for few days. The major reasons of frequent landslides at this location are poor geology, steep slope

and lack of retaining and drainage structures. The main area where the landslide is frequent is shown

below.


17

Photo: Overall view of landslide at left bank.

Fig 7: Sketch showing the lay out plan of the landslide area at Lete (asset 3).


18

Watershed context

The asset lies in the watershed of Lete Khola. The watershed area of the Khola at this location is 15

sq.km. But the main cause of landslide is not the Lete Khola but the hill slopes of both sides of the

bridge whose slope is very erodible and steep. The surface water accumulated at hill slopes is the

main cause of landslides. Moreover the whole area lacks vegetations. This aspect also is aggravating

landslides.

Asset location

The landslide areas are located at km 42 of Beni-Jomsom Road. The whole area is mountainous with

steep hill slopes. As mentioned above the hill slopes are steep and erodible. In addition to above

there is some probability of toe erosion of the road area by Lete River which is about 20m below the

road level.

Asset condition

The condition of road at this area is very poor as very few protection and drainage structures are

provided. Its condition will improve only after its upgradation when sufficient retaining and drainage

structures will be provided.

Asset design

Same as for Asset 2.


The road is frequently blocked by landslides. In July 2013 also the road was closed for few days by

landslides.


DoR is responding promptly when the road is blocked by landslides but has not constructed any

protection works till now.


Same as for Asset 2.


Adaptation location

There are not adaptation measures. DoR is planning to construct 35 m long breast walls towards Beni

Side from Lete Bridge.


Not applicable

Threat description

The road is vulnerable to frequent landslides. In addition to it, the asset is also threatened by the toe

erosion by Lete River. In order to minimize the threat sufficient protection and drainage structures

should be provided at landslide areas.

Past Extreme Events and impacts

Closure of traffic by landslides is common phenomenon. Beside this, there are no extreme events.


19

Adaptation Design

There are no adaptation measures until now.

Adaptation Success

Not applicable.

ASSET 1: ROAD DAMAGE BY PODKYU KHOLA AT

MARPHA

Overall view of road damage and debris deposition. According to the local people, the Khola

washed away substantial road length at both sides due to heavy flood in July 2013. The flood was

caused by continuous rain for three days, which is a rare incident for that area.

Right bank of the Khola. As seen the soil is loose and there are very little vegetations. As a result

the road side hill slopes are easily eroded even by small rainfall.

Photo of left bank This bank is rocky at the top but the soils at lower portion from where the road

passes are loose and are not very stable.

View of the right bank. The whole mountain slope at this bank is made of loose, erodible and

unstable slope.

Timber bridge along the existing temporary crossing. Due to washing away of the road sections,

DoR opened temporary road crossing at about 60m downstream of the previous road alignment.

View of road towards Jomsom side (left bank). The upper part of the hill is rocky and stable.

However, the area from where the road passes is weathered and hence minor slips are common at

this area.

ASSET 2: ROAD EROSI ON AT TUKUCHE

The Kaligandaki River washed away about 40m long section of road at this location in July 2010.

After the incident the road was realigned at about 10m towards hill side. Two persons can be seen

walking along the realigned road.

Washed away road section and upstream view of the Kaligandaki River. As seen on photo, the

river is still eroding the bank. During field visit it was found that the 1.5 km of road is vulnerable to

such erosion.


9

Spurs and gabion protection works are constructed at about 150m downstream of the washed

away section. Similar protection works will be required at other locations or the road should be

realigned.

About 200m long gabion walls are constructed at downstream of the spurs. These walls are

constructed to protect the apple farm of that area. This shows that the whole section is very

vulnerable to river erosion.


10

Photo of washed away road section. The photo was taken from adjacent road section. As seen the

soil is very loose and erodible.

Hill slope at the road damaged area. The whole area from where the road passes is highly

erodible. Hence it is highly vulnerable to landslides also.

ASSET 3: LANSLIDES A T LETE

Scar of landslide towards Jomsom side from the Lete bridge. According to DoR sub-engineer there

was heavy rain in July 2013 which triggered several landslides at both sides of the Lete Bridge.

Photograph of valleys side of the landslide. The valley side slope is very steep. As seen on photo

the Lete khola is very near to the road and the khola can erode the toe of the slope. A suspension

bridge which was was built for crossing before the construction of motorable bridge can also be

seen.

1 MYAGDI DISTRICT

1.1 District Sector Master Plan

All the 25 divisions of DoR are required to prepare Annual Road Maintenance Program (ARMP).

GoN/DoR allocates budget to the division only after the approval of the plan. The basic objective of

divisional ARMP is to identify and priorities/plan maintenance needs of the road assets in order to

bring the road Transport Cost to a minimum by optimum utilisation of available funds. This will help

the RB and DoR for proper and need based allocation of scarce resources towards maintenance & up

keeping of these national assets- the roads.

Following type of works (including road name, volume of works, budget requirement and

completion date etc.) are covered by ARMP.

1. Routine Maintenance

2. Recurrent Maintenance Program

3. Specific Maintenance Works

4. Periodic Maintenance

5. Rehabilitation Works

6. Other Works Programme

6.1 Upgrading

6.2 Emergency Maintenance

6.3 Bio-Engineering

6.4 Road Safety

6.4 Road Inventory/Register

6.5 Bridge Minor Maintenance

1.2 Sector budgeting and staff

Budgeting

The budget of Pokhara Division for FY 2012/13 and 2013/14 (proposed) is presented in a table in

Annex B.

Staff

The list of staff working in the Pokhara Division is presented in Annex C

1.3 Sector trends and issues

Pokhara Division which also looks after the strategic road networks (SRN) of Myagdi District is one

of the 25 divisions of DoR. Beside maintenance activities (routine, periodic, emergency, recurrent

etc.) the division also executes small to medium road and bridge projects.

1.3.1 Trends

The current trend of the divisions is as follows:


4

Planning

Planning of works is done by the respective divisions. The division is required to prepare annual road

maintenance plan (ARMP) for each year. After approval of the plan by Ministry/DoR, yearly budget is

provided to divisions. Without ARMP, the division will not be liable to receive the yearly budget.

Design & Construction

Assessment of needs, planning, design and estimation for all type of maintenance works are carried

out by the division staffs. However design works of new roads and bridges in general are carried out

by local consultants.

All the construction and maintenance works of roads and bridges are done by using local

contractors. The present trend in the construction has shifted from manual to machines. For

example at present construction equipment such as excavator, paver, dozer, roller are being used

more frequently.

Pokhara Division beside maintenance of roads and bridges, execute medium scale road and bridge

projects. The division recently completed two bridges along Maldhunga-Beni Road and constructing

two major bridges across Kaligandaki River.

Supervision of works is mainly done by division staffs.

Monitoring

The division mainly carries out the monitoring of : work programme, cost, quality and progress.

1.3.2 Issues

Major issues/difficulties faced by the divisions are as follows:

1. Delay in program approval and budget release timely;

2. Insufficient budget;

3. Very low bid by the contractors;

4. Contractors receive mobilization advance but do not execute in time;

1.4 Asset Inventory

The asset inventory for Myagdi is given in Annex E

1.5 Past extremes in the district

Past extreme events in the district are given in Annex D

1.6 Linkages to other sectors

The DoR at present is cooperating with the following agencies for implementation of RIWs:

DoLIDAR, DoI, DWSS, DWIDP, NT, NEA, Department of Transport (DoT)

Major Organization working in the District

World Bank is providing 10% of the maintenance fund to the division.

1.7 Priority infrastructure in Myagdi District

1.7.1 Prioritisation process

The key criteria for prioritisation include:


5

Infrastructure of national strategic importance

Infrastructure of district strategic importance

Infrastructure that has been impacted by past extreme events

Infrastructure located in areas prone to past extreme events

At least one planned infrastructure

The consultant in consultation with the division chief prepared final lists of the priority structures of

the district. The list was prepared following the criteria provided in District Office Report. The

priority list is given in table below

Bridge

During construction of abutments Kaligandaki River

washed away right bank near the right abutment. At

present , the gap between the right bank and the

abutment is 15m and water also flows through it. Due to

this, the length of the previously designed bridge has

become insufficient.

4 Bridge across

Kaligandaki River

near Beni Bazar

Major Bridge The bridge lies near the Beni Bazar, which is heavily

populated. Several protection measures are provided

at/around the bridge. Similarly houses at/near Benibazar

will be affected if the bridge is damaged.

5 Under construction

The contractor had erected all the formworks and had

placed all the reinforcements and was ready to concrete

the superstructure within few days. In the mean time an

instantaneous flood washed away all the formworks and

reinforcements.

2 MYAGDI DISTRICT: ASS ET BASELINE

2.1 Asset1: Beni – Jomsom Road at Doba (km 17)

Damaged section of the road. At present, DoR is constructing gabion wall to prevent the river from

coming to the road.

Sketch Plan of Site


7


Beni-Jomsom road is one of the most important roads of Myagdi District. It provides motorable link

to several important areas of the district as well as to Jomsom, the headquarter of Mustang District.

Motorable track of this road was constructed by Nepal Army. Nepal Army handed over this road to

DoR few years ago. At present, DoR is maintaining the road. DoR has still not any major

improvement works and hence the condition of the road is poor.

In July 2012, Sunari Khola which joins the Kaligandaki River at km 17, transported large amount of

debris. The debris obstructed the waterway of the river at right bank. As a consequence, the river hit

the road which located at the left bank and damaged about 80 m long section. DoR, at present is

constructing protection wallsto maintain the vehicular traffic.

Watershed context

The watershed of this road location is Kaligandaki River. Kaligandaki is the main river of the Myagdi

and almost all the rivers/streams of the district join this river at different locations. Several

kilometers of the Beni-Jomsom Road are located along steep bank of Kaligandaki River and hence

the asset is vulnerable to flood and landslides.

Asset location

Road protection works km 17 of Beni-Jomsom Road which is being constructed is considered as

asset for the purpose of this study. The road at this location is constructed by cutting steep rocky

area (see photos). Due to steep rocky slope, the main vegetations are barren land and bushes.

Sunari Khola joins this river at the opposite side of the road. The debris of Sunari Khola is the main

reason of road damage.

The area where the road is located rocky and stable, there is a very little probability of slope failure

Asset condition

DoR is constructing stone masonry, concrete and gabion walls at this location. The condition of

these walls is satisfactory and any major damage to the asset was not observed. However, the

condition of road is poor.

Asset design

Stone masonry and concrete walls are already constructed at this location and about 20 long gabion

walls are under construction and their design is adopted from standard design.


In July 2012, the Sunari Khola deposited large amount of debris and obstructed the flow of

Kaligandaki River at right bank. Due to obstruction at right bank, the river damaged the road which is

located at left bank.

As the road is located is frequently damaged by the river especially during high flood.


As the road is newly constructed there were no earlier adaptation responses


The adaptation measure seems adequate but it is not clear why the DoR is constructing three

different types of structures (stone masonry, concrete and gabions) to protect of road from the

same problem.


8


Adaptation location

The various adaptations are situated at different sites along the alignment


As the walls, gabions etc are under construction their condition is good

Threat description

The road and the adaptation work are threatened by increasing river levels and flow speeds due to

increased rainfall in the catchment area.


The high flood in 2012 caused increased sedimentation which obstructed the flow of the

Kaligandhaki which damaged the road.

Adaptation design

The different types of structure being constructed to protect the road are yet to show their

appropriateness under high flood conditions.

Adaptation success

As the construction of wall is still not complete, it was not possible to assess the adaptation

responses.

2.2 Asset 2: Road Rehabilitation at Timure Bhir at km 16 on Beni – Jomsom Road

Newly constructed road section at Timure Bhir. The elevation of the previous road alignment is

about 5 meter lower than the existing one at the center of the landslide.


There was a big landslide at Timure Bhir at km 16 of Beni-Jomsom Road in 2012. The landslide

washed away about 50 long section. DoR reconstructed the road by shifting the alignment towards

hill side. However, the new road has steep gradient and DoR is planning to improve it in near future

Watershed context

The watershed of this road location is Kaligandaki River. Kaligandaki is the main river of the Myagdi

and almost all the rivers/streams of the district join this river at different locations. Several

kilometers of the Beni-Jomsom Road are located along steep bank of Kaligandaki River and hence it

is vulnerable to flood and landslides.

Asset location

Timure Bhir lies at km 16 of Beni-Jomsom Road. There are not any man made features such

as walls, drainage structures etc.

The road at this location is constructed by cutting steep slope (see photos). The land area

at/around the Timure Bhir is covered with bushes and trees.

The road is constructed by excavating steep area (of weathered rock) and hence there is

high probability of ground instabilities.

Asset condition


10

DoR has just opened the motorable track for traffic movement and requires several improvement

works. It has steep gradient of more than 15 % at both sides and the road width at the gully is less

than the standard width. In addition to it the cut slope is very steep and vulnerable to slope failure.

Asset design

The road track was opened without any detail design.


About 50m long road section was washed away at this location in August 2012.


Prior to the flood in 2012 there had not been any adaptations carried out.


The design of the road alignment to follow closely the river alignment along the bottom of a very

deep and narrow valley has to be questioned although it has to be accepted that any alternative

alignment would involve very difficult engineering work.


Adaptation location

The adaptation is located at the site of a large landslide which occurred in 2012 demolishing 50

metres of road. The adaptation consists of a change of alignment of the road so that the road is

moved up the slope of the mountainside and away from the river.


The completed work is in reasonable condition although the alignment is very steep both sides of

the original landslide location.

Threat description

The threat to the road is from future increased floods due to increased rainfall in the catchment area

and subsequent erosion of the hillside beneath the newly aligned road. There is also a threat of

additional landslides from above the road due to increased intense rainfall.


The only recorded extreme event is the landslide in 2012 which destroyed 50 metres of road.

Adaptation Design

No detailed design was carried out before carrying out the work. The new alignment is very steep

both sides of the central landslide area and then passes through a very steep sided cutting which

increases the likelihood of further landslides in the future as the intensity of rainfall increases.

Adaptation Success

The adaptation is successful in the short term.


11

2.3 Asset 3: Bridge across the Kaligandaki River near B eni Bazar

View of the bridge from the upstream left bank. Its condition is satisfactory and there are no

major problems affecting the bridge stability at present


This is one of the most important bridge of the district as it links Myagdi District as well as Beni

Bazzar with other parts of the country. It is a located at km 12+300 of Maldhunga-Beni Road (F133).

The bridge has three spans and its total length is 76.4 meter. The substructures (abutments and

piers) of the bridge are constructed of RCC and all the superstructure members except main beams

of central span (which is constructed of steel) are also constructed of RCC.

DoR has constructed several protection structures at both upstream and downstream of the bridge.

The overall condition of the bridge is good whereas the condition of protection works is satisfactory

except at few locations.

Watershed context

The watershed of this bridge location is Kaligandaki River. Kaligandaki is the main river of the Myagdi

and almost all the rivers/streams of the district join this river at different locations. The bridge as

well as the adjoining areas are vulnerable to flooding by Kaligandaki River.

Asset location

The asset is located near the Beni Bazaar, the headquarter of Myagdi District. The left side of the

bank near the river is steep hills. Main types of vegetation at this side are bushes, forests with and

cultivated land. The right bank of the river is covered by the Beni Bazar. The slope of the bazaar is

relatively gentle in comparison with other bank. Major concern at this sites is that the houses at left

bank are very near to the steep slope and hence may collapse in case of slope failure.


12

The ground at both sides of the river near/at the bridge site is stable.

Asset condition

The condition of the bridge is good. There is no damage to superstructure and substructures.

However, the protection works which consist mainly of gabions are in damaged condition at several

locations.

Asset design

The bridge is designed as a simply supported structure of three spans with a total length of 76

metres.


There has not been any significant event after the construction of the bridge.


Gabion walls are provided for protection of banks and the bridge. The adaptation responses of these

protection structures are satisfactory.


The design of bridge and protection structures is appropriate. The bridge length is sufficient and the

structure does not disturb the hydrological regime of the river. Similarly, circular RCC piers are

designed in order to withstand the boulder impactAdaptation


Adaptation location

Gabion protection works are provided to a sufficient length both upstream and downstream of the

bridge.


The adaptations of gabion walls are in poor condition in several locations

Threat description

The threat to the bridge and the adaptation work is from increased high flood levels and flows due

to intense prolonged rainfall in the catchment area caused by climate change. The damage to the

gabions increases the threat posed by extreme weather events.


There have been no recorded extreme events in the recent past.

Adaptation Design

The adaptation design is appropriate for present conditions.

Adaptation Success

The adaptations have succeeded in preventing the possibility of erosion threatening the stability of

the bridge

ANNEX E: PHOTOGRAPHS ASSET 1

At right side of the photo, the heap of gravels and boulders is the debris deposition by Sunari

Khola. This deposition pushed the River towards left bank and is the main cause of the road

damage at this location.

It is very difficult to realign the road towards left side due to very steep rocky slope.


7

View of debris deposited by Sunari Khola. According to the district technicians, the bed level of the

Sunari Khola was raised by 2-3 meter after debris deposition.

Photo of reconstructed road section which is protected by stone masonry.


8

ASSET 2

The gradient of the road is about 15% at both sides from the main slide area. DoR is planning to

improve the whole road section in near future.

Middle section of the realigned road. Road at this location required huge gully cutting. As seen on

the photo, the side slope on both sides is very steep and may fail if proper protection works are

not provided.


9

Previous road alignment. As seen on photo, there is no trace of previous alignment at the steep

(rocky) area as the whole road section was washed away.

The whole soil material excavated during reconstruction of road is dumped at river. The dumped

material is obstructing the river flow. Due to flow obstruction, the regime of the river has been

disturbed and hence there is always possibility of damage at another location. The soil materials

should have been deposited properly at a location.


10

ASSET 3

Photo of right bank showing gabion protection works, bus stand and Beni Bazaar. The condition of

the protection works is good except at few locations.

A motorable road track is constructed at the right bank by constructing a very long gabion bank

protection works. In order to construct this road the authorities have excavated the slope at hill

side. This increased vulnerability to the houses located at the top of the slope.


11

As mentioned in the photo above, the houses seen on photo are very near the vertical slope. In

case of slope failure, several houses will collapse.

Landless squatters have constructed houses at the left bank near the bridge. These houses may be

damaged if there will be a big flood at Kaligandaki River.
