Chapter I

INTRODUCTION

Background of the Study

Assessment is the evaluation or estimation of the nature, quality, or ability of

someone or something. Soil erosion is when a raindrop hits soil that is not protected

by a cover of vegetation and where there are no roots to bind the soil, it has the

impact of a bullet. Soil particles are loosened washed down the slope of the land

and either end up in the valley or are washed away out to sea by streams and rivers

Erosion removes the topsoil first. Once this nutrient-rich layer is gone, few plants

will grow in the soil again. Without soil and plants the land becomes desert like and

unable to support life. Coconets are made from 100% coir fiber twine woven into

high strength nets for extreme slope stabilization, protection of high velocity stream

banks and high velocity intermittent flow channels. The natural coconut coir material

perform very well in applications such as erosion control blankets for landscaping

(Cereno et. al. , 2011).

In Sri Lanka soil erosion is listed as the main environmental problem related

to land. Mulching is an effective agronomic method of soil and water conservation if

suitable material can be found. The objective of this study was to evaluate three

types of coconut fiber matting for soil and water conservation in an Ultisol of Sri

Lanka. This was carried out using erosion plots and soya bean as the reference

crop. The results showed that coconut fiber matting reduced run-off and soil loss

significantly. Soil loss reduced from 18.2 than in no mulch plots to 0.7 t/ha in

mulched plots during the 3.5 month growing season. Closely woven coconut fiber


10/33

matting was the most effective as it was dense and covered the total land surface.

The soil moisture depletion was less in mulched plots during the longest dry period

due to increased infiltration and less evaporation. Soil temperature was reduced by

4C when mulched with coconut fiber matting and the diurnal temperature variation

also decreased. The carbon nitrogen (C:N) ratio of coconut fiber matting was very

high when compared to a commonly used green manure species, showing its low

decomposition rate. The dry matter production and seed yield of soya bean was

significantly higher in mulched plots. With the long lasting characteristics combined

with biodegradability, these materials hold great potential for long term soil erosion

control (Mapa,2012).

In the Philippines, after a devastating landslide in Leyte, CocoTech (a

privately-held enterprise in the Philippines that produces geo-textiles from waste

coconut husks.) was hired by a private European organization to install coconets on

the hillsides and mountains whose collapse wiped out entire villages. In addition,

Cocotechs coco-peat products were used to help restore the farmlands that had all

but disappeared. Today, the mountains and hillsides are sprouting vegetations, and

farmlands are once again retuning to productive uses, albeit not as yet fully restored

to their original conditions. The most important thing is that land and soil have been

rejuvenated and will be in better condition than before the disaster (Ganchero &

Manapol, 2007)

In the study conducted by Bureau of Research and Standards (BRS) of

DPWH, results showed that the method of using Geonets (specifically, coconets) to

protect developing vegetation against water and wind erosion have proven to be

essential since it provides the soil surface with partial shading, moderation of soil


11/33

temperatures and moisture retention. These materials are prescribed to initially

stabilize the soil but without live plants and trees.the effective erosion control would

not be achieved. The benefits of applying Bioengineering techniques such as the

use of hydroseeding and coconets in accelerating vegetation helps control soil

erosion and stabilize the soil. With the use coco coir products as slope protection,

slope above the road will be prevented from caving in. Thus, damages triggered by

soil erosion on infrastructure such as roads and bridges will be prevented if slope

protection is present.

At present, the use of inert materials such as concrete and steel had always

been relied as for slope stabilization and soil erosion. The widespread of these

materials as stone riprap and concrete are now abridged due to its high cost. The

use of CocoNet Reinforcement in Brgy. Sabang, Naval, Biliran is not far from the

above stated. The stiffness of the soil may erode if non-stop intense rains arise that

may have an effect on the transportation, delivering of freight and a lot more

wherein it can block the roadway. The appliance of Coconet has a big impact on

helping to prevent from soil to grind down. Coconet promotes the growth of new

vegetations by absorbing water and preventing the topsoil from drying out.

This study was made to determine the capacity of the Coconet

Reinforcement wherein we can identify what should be the best soil erosion

prevention that could last up for years.

Objectives of the Study

This main purpose of this study was to assess the soil erosion prevention

using Coconet Reinforcement in Brgy. Sabang, Naval, Biliran.


12/33

Specifically, this study sought to answer the following objectives:

1. To ascertain the physical properties of the Coconet that helps to prevent

soil erosion in terms of;

1.1 thickness of the Coconet used;

1.2 unit weight;

1.3 number of twines in crosswise direction;

1.4 number of twines in lengthwise direction; and

1.5 water absorption

2. To ascertain the maintenance system applied on the Coconet

Reinforcement in Brgy. Sabang, Naval, Biliran.

3. To ascertain the problems met related to the use of Coconet

Reinforcement for soil erosion prevention in Brgy. Sabang, Naval, Biliran; and

4. To propose a new soil erosion prevention scheme for the soil erosion

prevention in Brgy. Sabang, Naval, Biliran.

Framework of the Study

The theoretical and conceptual frameworks of the study will be presented as

follows:

Theoretical framework. This study was anchored on theories that give

meaning and purpose to the basic considerations of the research.

One basic thought that primarily relates to the rationale of this study is the W.

E. H. Cullings Theory of Erosion on Soil-Covered Slopes. The theory states that

Slope erosion is, characteristically, erosion without corrasion. In contrast to all other

aspects of erosion, transportation processes occupy a secondary role; with

exceptions the actual movement of material on slopes does not of itself lead to the


13/33

5

production of further removable material. The exceptions, significantly, occur at

extreme positions, where the acceleration is such that falling rocks strike off

splinters; where transportation is catastrophic, as in land- slides; or where

increasing amounts of water herald a transformation to fluvial erosion, as in

sheetfloods. On the majority of slopes transportation processes can only influence

weathering processes in a negative manner; they are unable to increase the

production of removable material though they may, by their inefficiency, bring about

a decrease. Slope erosion is by far the least efficient means of landscape reduction;

if it were not so, diversification of the terrain would more closely reflect structure and

endo-genetic activity transporting agents on the slopes are performing below

capacity (Culling, 2011).

Conceptual framework. The main purpose of this study was to assess the

use of Coconet Reinforcement for soil erosion prevention.

The parameter of this study covers the properties of the Coconet

Reinforcement that helps to prevent soil erosion in terms of the thickness of the

Coconet used, the unit weight, number of twines in Crosswise direction, number of

twines in Lengthwise direction and the water absorption. The Maintenance System

and Problems met related to the used of the Coconet.

Figure 1 presents the conceptual framework of the study.

Importance of the Study

The researcher believes that this study will be the utmost importance to the

following:

Barangay officials. The results of this study will provide barangay officials

responsibility on their society that the heavy rains may arise, the Coconet

reinforcement with no plants grown is at risk. Landslide may happen.

Residents. The result of this study will give awareness to the residents the

capacity of the Coconet that anytime when heavy rain occurs, major disaster may

happen and worst can kill other peoples lives.

Future researchers. They will have this study as their reference in making

their own research study on coconet reinforcement and can improve more sufficient

and effective soil erosion prevention scheme.

Scope and Delimitations of the Study

The study covered only the soil erosion prevention using coconet

reinforcement at Brgy. Sabang, Naval, Biliran.

The study will be confined to the Department of Public Works and Highways.

The main information in this study will be the Planning Section of the Department of

Public Works and Highways Office where all the reliable and needed data of the

Coconet Reinforcement are systematically stored and gathered.

Definition of Terms

The terms used in this study will conceptually and operationally defined as

follows:


16/33

8

Coconet reinforcement. Any coconut coil fiber-based material such as

Coconets, Cocologs, Coco peat, placed in sloping lands and embankments to hold

the vulnerable soil and permit vegetative growth to control surface erosion and

conserve the productivity of the soil.

Soil Erosion. Soil erosion is a naturally occurring process that affects all

landforms most especially slope lands like from the Brgy. Sabang wherein due to

torrential rains the Coconet broke down that leads to major soil erosion that made

the problem worse. The major problem of the landslide is the stiffness of the soil,

wherein it was like a wall of soil that is prone for land erosion even if moderate rain

occurs.

Review of Related Literature

This chapter presents the readings and studies related for this study. The

readings will be taken from books, articles in periodicals and journals, while the

cited related literature below will be based on computer researches as reported in

research journals, thesis and dissertations.

The relation between the rate at which the parent rock is reduced by

weathering and the rate at which the products of weathering are removed provides

a means of describing and classifying the properties and behavior of slopes subject

to erosion. The two modes of erosion interact over a continuous range; at one

extreme the influence of weathering is predominant, and the surface of the

landscape is covered with a thick layer of weathered rock material; at the other

extreme the agents of transportation are capable of stripping a slope bare of all

removable rock fragments.

Within the transition zone the subordinate mode qualifies the performance of

the major by reducing it below the potential set by the given conditions. In neither

case can the action of one mode accelerate the activity of the other above the

potential asset, and to reach this level will require the elimination of the other mode

as an effective agent of erosion. In slope erosion we are concerned with a minimal

process of a type common to many fields of study, pedology (Liebigs law of the

minimum), chemical kinetics, and especially economic theory. In fact, by regarding

the agents of transportation as the creators of a demand for weathered material and

weathering as a means of supplying transportable material, denudation of the

landscape can be reduced to a problem of supply and demand (Culling, 2011)..

The rate of weathering depends upon a host of conditions so that its range of

variation is considerable, while the variation itself is liable to rapid, if not

discontinuous, change both spatially and temporally. This is in marked contrast to

the variables involved in the rate of material transport, especially where, as on soil-

covered slopes, they may be regarded as continuous and of limited variation. If

denudation were merely a matter of transportation, a great deal of 230 the diversity

would be lost to the landscape. On the other hand, the existence of regular surfaced

landforms implies that transporting processes are able to assume a predominant

role. On surfaces of low relief and adequate rainfall, soil creep is the responsible

transport agent and supplies the dominant mode of denudation, with the result that

structure is masked by regularity of surface form. It is only when dissection

increases slope declivity, so increasing the effective demand of the transporting

agents up to the level of supply, which variations in rock resistance are able to


18/33

10

make themselves felt. A structurally determined landscape is one in which the

transporting agents on the slopes are performing below capacity (Culling, 2011).

A series of laboratory model tests on a strip footing supported by sand

reinforced by randomly distributed Coir fiber and mesh elements was conducted in

order to compare the results with those obtained from unreinforced sand and with

each other. For conducting the model tests, uniforms and was compacted in the test

box at its optimum moisture content and maximum dry density. Three types of

reinforcement, two sizes of mesh elements having the same opening size and one

size of fiber element cut from the meshes, were used in varying amounts in the

tests (Wasti and Butun, 1996).

RESULTS AND DISCUSSION

This chapter presents the discussion of the data generated as articulated in

the objectives. The first section describes the basic information of the physical

properties of the Coconet that helps to prevent soil erosion. The second section

describes the maintenance system applied on the Coconet Reinforcement. Third

section describes the problems encountered related to the use of Coconet

Reinforcement for soil erosion prevention. The fourth section describes the

proposed soil erosion prevention scheme for the soil erosion prevention.

Profile of the Coconet

The Coconet used in Brgy. Sabang, Naval, Biliran was the Coconet 400

wherein the water absorption is 163 Min, the uppermost among all water absorption

percentage in the three kinds of Coconet, meaning it has the strongest capacity to

prevent soil erosion . Table 1 below indicates the physical properties of the

Coconet.

Maintenance System Applied

Engr. Alfredo L. Bollido, Chief of Maintenance Section of The Department of

Public Works and Highways BDEO articulates that there was no maintenance

system applied on the said reinforcement only that they embedded the deeply

rooted grasses specifically the vetiver grasses wherein the roots can hold the soil

much better than the usual. Planting vetiver grass would have an immediate impact

on erosion. The other important function of vetiver grass is it forms a windbreak to

slow the force of winds sweeping up the bare hillside, so that native grass and herb

seeds would not be blown away and have a rapid growth of native ground covers

that provides the second line of defense against erosion.

Problems Encountered

On July 20, 2014 the entire Province of Biliran where hit by the Typhoon

Henry that brought torrential rains cause severe flooding in the Municipality of

Almeria as well as the Municipality of Naval. The typhoon also causes major

landslide along the National Road of Biliran and one of those is the Coconet

Reinforcement in Brgy. Sabang, Naval, BIliran. (Bandila, ABS-CBN News, July 21,

2014)

According to BiliranIsland.com (July 21, 2014) the rain experienced in

Municipality of Almeria (where Brgy. Sabang is nearest to) raised up to 26.67mm

the highest rainfall level in the entire Province, thus the Coconet Reinforcement in

Brgy. Sabang didnt carry the torrential rain. The reinforcement broke down and

cause major landslide.

New Soil Erosion Prevention Scheme

The National Office of DPWH, introduced to its DPWH Regional offices

nationwide the use Bio-Engineering Solution the Coconet Reinforcement as an

alternative way to prevent soil erosion. Yet the lifespan of the said reinforcement

can stay up to 2-4 years only. So, the DPWH Biliran District Engineering Office,

go back to its widely used soil erosion prevention scheme the use of Retaining Wall,

it is expensive yet long-lasting. Here are 5 benefits in installing a concrete retaining

wall: provides functional support for keeping soil in place; prevent sink holes and

eliminating the eye sore of dirt piles and hills; helpful in preventing flooding; reduces

maintenance and prevents erosion; and prevent damage to property or surrounding

structures.

Chapter IV

SUMMARY, CONCLUSION AND RECOMMENDTATION

The study aimed to assess the soil erosion prevention using Coconet

Reinforcement in Brgy. Sabang, Naval, Biliran; determine the maintenance system

applied on the Coconet Reinforcement; propose a new soil erosion prevention

scheme for the soil erosion prevention in Brgy. Sabang, Naval, Biliran; and

ascertain the problems met related to the use of Coconet Reinforcement for soil

erosion prevention

Summary of Findings

1. The physical properties of the Coconet were thickness of the Coconet 400

mm; Unit Weight 1 g/m^2 is 400+20; number of twines in crosswise direction is 40

Min; number of twines in lengthwise direction is 40 Min; and Water Absorption is

163 Min.

2. There was no maintenance system applied to the reinforcement only that

they embedded the deeply rooted grasses specifically the vetiver grasses wherein

the roots can hold the soil much better than the usual.

3. The Coconet Reinforcement broke down last July 21, 2014 due torrential

rains brought by Typhoon Henry that cause major landslide in that area.

4. The DPWH BDEO go back to the use of Retaining Wall for it is finest

slope protection that could last up for years.

Conclusion

Based on the aforesaid findings of the study, the following conclusions were

drawn:


25/33

17

1. The use of Coconet Reinforcement could only stay up to 2-4 years. It is

not economical for lifetime slope protection because it is not suitable to change the

said reinforcement years after years, big amount would be spent for. However, if

using retaining wall, it may be much expensive than the Coconet, it could last up for

years.

Recommendations

Based on the findings and conclusion of the study, the researcher advances

the following recommendation:

1. To achieve the costeffective soil erosion prevention I can acclaim the use

of Retaining Wall, it has a strong foundation, strong materials and heavy-duty. And

if theres maintenance system applied on the Retaining Wall, we can realize the

picture-perfect soil erosion prevention scheme. Yes, it may be very expensive but

the effect is reasonable.

The use of Coconet Reinforcement is upright for it is Bio Engineering, its just that

not that long lasting not good for lifetime protection wherein it can only stay up to 2-

4 years. The use of Coconet Reinforcement in Brgy. Sabang, Naval, Biliran was not

able to satisfy the soil erosion prevention wherein it broke down due to torrential

rain, yes it justify the lifespan because the Coconet has able to protect for three

years but not economical because

So to achieve the costeffective soil erosion prevention I can acclaim the use

of Retaining Wall, it has a strong foundation, strong materials and heavy-duty. And

if theres maintenance system applied on the Retaining Wall, we can realize the


26/33

picture-perfect soil erosion prevention scheme. Yes, it may be very expensive but

the effect is reasonable!
