Executive Summary
On the request of M/s WAPCOS Limited, 76-C, Institutional Area,
Sector-18, Gurgaon-122015, Haryana, a survey was carried out to
demarcate the High Tide Line(HTL), Low Tide Line(LTL) and Coastal
Regulation Zone(CRZ) for the proposed project “Dredging of Navigational
Channel in an area between Mazagon Dock Shipbuilders Ltd and Mumbai
Port in Maharashtra(covering 7 Km radius area around the proposed dredging
project site)”. The satellite imagery of the project area was interpreted for
topographic and geomorphic features in the vicinity of the proposed project
site. The proposed site falls in the vicinity of Arabian sea.
Institute of Remote Sensing(IRS) in Anna University, an agency
authorized by MoEF, Government of India for the demarcation of HTL & LTL
has conducted required field surveys and measurements for demarcation of
CRZ in the last week of August 2016. Based on the geomorphology and
topography in the vicinity of project area, HTL has been identified and traced
in the field by Kinematic GNSS survey. LTL has also been identified based
bathymetry and geomorphic conditions of the project area. The HTL and LTL
along with setback lines as per CRZ Notification 2011 were superimposed on
to georeferenced cadastral map to prepare a local level CRZ map at 1:4,000
scale. The layout of proposed dredging location as provided by the client was
superimposed on the CRZ map. The co-ordinates of the HTL in WGS84
system are presented in the Annexure-I.
The location of the proposed project “Dredging of Navigational
Channel in an area between Mazgaon Dock and Mumbai Port in
Maharashtra” falls in CRZ-IVA as per CRZ notifications, 2011.

1.0 INTRODUCTION
1.1 Coastal Regulation Zone
The coastal zone is the area of interaction between land and sea. The
coastal Zone of Maharashtra has a very high concentration of population
along with ecologically sensitive areas like mangroves. There is a spurt of
developmental activities arising from huge residential colonies, new industries
and tourism centres along the coast and in coastal zone. There is a need to
protect the coastal environment while ensuring continuing production and
development. This zone is extremely vulnerable and has to be managed
judiciously striking a balance between ecological and developmental needs.
Government of India has issued a notification during February 1991
for regulating the developments along the coastal stretches of seas, bays,
estuaries, creeks, rivers and backwaters which are influenced by tidal action.
The land between 500 meters from the High Tide Line (HTL) and the Low
Tide Line (LTL) is identified as Coastal Regulation Zone (CRZ). The coastal
stretches within CRZ are classified into four categories, namely, Category I
(CRZ-I), Category II (CRZ-II), Category III (CRZ-III) and Category IV (CRZ-
IV). The notification has also laid down regulations to regulate the various
activities in the coastal zone. The Ministry of Environment and Forests,
Government of India, has approved a set of CRZ maps on 1:25,000 scale
prepared from SPOT satellite imagery. On these maps, zones are
demarcated as CRZ I, CRZ II and CRZ III, by Coastal Zone Management
Authority.

Page 6 of 37
Coastal Regulation Zone I includes the zone between High Tide Line
and Low Tide Line. It also includes the areas that are ecologically sensitive
and important, such as national parks/marine parks, sanctuaries, reserve
forests, wildlife habitats, mangroves, corals/coral reefs, areas close to
breeding and spawning grounds of fish and other marine life, areas of
outstanding natural beauty/historically/heritage areas, areas rich in genetic
diversity, areas likely to be inundated due to rise in sea level consequent upon
global warming and such other areas as may be declared by the Central
Government or the concerned authorities at the State/Union Territory level
from time to time.
CRZ-II covers the areas that have already been developed up to or
close to the shoreline. For this purpose, the "developed area" is referred to as
that area within the municipal limits or in other legally designated urban areas
which are already substantially built up and have been provided with drainage
and approach roads and other infrastructural facilities, such as water supply
and sewerage mains. CRZ-III covers the areas that are relatively undisturbed
and those which do not belong to either Category-I or II. These include the
coastal zone in the rural areas (developed and undeveloped) and also areas
within municipal limits or in other legally designated urban areas which are not
substantially built up. CRZ-IV refers to the coastal stretches in the Andaman
and Nicobar, Lakshadweep and small islands other than those designated as
CRZ-I, CRZ-II or CRZ-III.
The Ministry of Environment and Forest in the CRZ Notification, 2011
declared the following areas as CRZ and imposed with effect from the date of
the notification the restrictions on the setting up and expansion of industries,
DEMARCATION OF HIGH TIDE LINE, LOW TIDE LINE AND COASTAL REGULATION ZONE FOR THE PROPOSED PROJECT “DREDGING OF NAVIGATIONAL CHANNEL IN AN AREA BETWEEN MAZAGON DOCK SHIPBUILDERS LTD AND MUMBAI PORT”

operations or processes and the like in the CRZ. The areas that are defined
as CRZ as per CRZ Notification, 2011 are
(i) The land area from High Tide Line (HTL) to 500 mts on the
landward side along the sea front.
(ii) CRZ shall apply to the land area between HTL to 100 meters or
width of the creek whichever is less on the landward side along the tidal
influenced water bodies that are connected to the sea and the distance
upto which development along such tidal influenced water bodies is to be
regulated shall be governed by the distance upto which the tidal effects are
experienced which shall be determined based on salinity concentration of 5
parts per thousand (ppt) measured during the driest period of the year and
distance upto which tidal effects are experienced shall be clearly identified
and demarcated accordingly in the Coastal Zone Management Plans.
(iii) The land area falling between the hazard line and 500mts
from HTL on the landward side, in case of seafront and between the
hazard line and 100mts line in case of tidal influenced water body the word
„hazard line‟ denotes the line demarcated by Ministry of Environment and
through the Survey of India taking into account tides, waves, sea level rise
and shoreline changes.
(iv) Land area between HTL and Low Tide Line (LTL) which will be
termed as the intertidal zone.
(v) The water and the bed area between the LTL to the territorial water
limit (12 Nm) in case of sea and the water and the bed area between LTL at
the bank to the LTL on the opposite side of the bank, of tidal influenced water
bodies.

The Classification of the CRZ is also modified for the purpose of
conserving and protecting the coastal areas and marine waters as CRZ – I,
CRZ – II, CRZ – III and CRZ – IV. The CRZ – I include the areas that are
ecologically sensitive and the geomorphological features which play a role in
the maintaining the integrity of the coast like (a) Mangroves(b) Corals and
coral reefs and associated biodiversity (c) Sand Dunes (d) Mudflats which are
biologically active (e) National parks, marine parks, sanctuaries, reserve
forests, wildlife habitats and other protected areas (f) Salt Marshes (g) Turtle
nesting grounds (h) Horse shoe crabs habitats (i) Sea grass beds (j) Nesting
grounds of birds (k) Areas or structures of archaeological importance and
heritage sites and the area between Low Tide Line and High Tide Line. The
CRZ-II includes areas that have been developed upto or close to the
shoreline. The CRZ-III includes areas that are relatively undisturbed and
those do not belong to either CRZ-I or II, which include coastal zone in the
rural areas (developed and undeveloped) and also areas within municipal
limits or in other legally designated urban areas, which are not substantially
built up. The CRZ-IV includes the water area from the Low Tide Line to twelve
nautical miles on the seaward side and the water area of the tidal influenced
water body from the mouth of the water body at the sea upto the influence of
tide which is measured as five parts per thousand during the driest season of
the year.
The Ministry of Environment and Forest has also provided guidelines
for demarcation of High Tide Line in the CRZ Notification, 2011. As per the
guidelines, Cadastral (village) maps in 1:3960 or the nearest scale shall be
used as the base maps. HTL and LTL will be demarcated in the cadastral

map based on detailed physical verification using coastal geomorphological
signatures or features in accordance with the CZM Maps approved by the
Central Government. 500metre and 200metre lines shall be demarcated with
respect to the HTL.
In order to facilitate classification of Coastal Regulation Zones,
Government of India has approved few agencies/institutions across the
country vide Lr. No. J17011/8/92-1A III, dated 10.05.1999 of Ministry of
Environment and Forests. Institute of Remote Sensing, Anna University being
one of them, has been carrying out HTL and LTL mapping following the
guidelines issued by Ministry of Environment & Forests, Government of India.
1.2 Background
M/s WAPCOS Limited, 76-C, Institutional Area, Sector-18,
Gurgaon-122015, Haryana, has requested Institute of Remote Sensing,
Anna University to demarcate HTL, LTL and CRZ for the Sea/Bay/tidal
influenced water bodies and ecologically sensitive areas on 1:4,000 scale in
the vicinity of their site for the proposed project “Dredging of Navigational
Channel in an area between Mazagon Dock Shipbuilders Ltd and Mumbai
Port in Maharashtra(covering 7 Km radius area around the proposed dredging
project site)”. The proposed project site has proximity to Arabian sea. It is in
this context, the proposed site needs to be evaluated to assess whether the
proposed site falls under regulations of CRZ Notification, 2011. Hence IRS
has taken up a ground verification survey for demarcation of HTL, LTL and
ecologically sensitive areas for preparation of local level CRZ Map.

1.3 Objectives
The objective of the present study is to examine the site for the
proposed project “Dredging of Navigational Channel in an area between
Mazagon Dock Shipbuilders Ltd and Mumbai Port in Maharashtra(covering 7
Km radius area around the proposed dredging project site)” with reference to
CRZ Notification, 2011. Keeping in view of the requirements of notification,
Institute of Remote Sensing, Anna University under took the project with
following agreed scope of work:
Demarcation of HTL, LTL near project site(covering 7 km radius area) by
conducting DGPS survey in the field.
Demarcation of ecologically sensitive entities such as Mangroves, Sand
dunes, etc if any in the vicinity of project site.
Superimposition of HTL,LTL and ecologically sensitive areas along with
the project site on georeferenced cadastral map.
Demarcation of Coastal Regulation Zones in the neighbourhood of the
project site.
1.4 Equipment and Data Products
The field verification of HTL, LTL, ecologically sensitive areas and tidal
influence in water bodies is carriedout using advanced accurate survey and
insitu measurement instruments like GNSS, Total Station, and Salinity Meter.
The data products used for demarcation includes Satellite Imagery, Survey of
India Topographic Maps, NHO Navigation Charts, Bathymetric Data and Tide
Tables. For demarcation of High Tide Line during field verification of Coastal
Geomorphology and Topography, dual frequency GNSS receivers were used

Accuracy in High Precision Static GNSS Surveying o Horizontal Accuracy is 8 mm + 1 ppm RMS o Vertical Accuracy is 15 mm + 1 ppm RMS
Salinity in the tidal influenced water bodies is verified using insitu
measurements of salinity with a salinity meter. As per CRZ Notification, 2011
the HTL shall extend in tidal influenced water bodies till the salinity a
concentration of 5 parts per thousand. Hence an salinity meter is used to
assess tidal influence during High Tide in the water bodies along with
geomorphology and vegetation signatures near the study area.
The IRS P6 satellite images of the study area along with other satellite
images from web based sources were used for reconnaissance and
DEMARCATION OF HIGH TIDE LINE, LOW TIDE LINE AND COASTAL REGULATION ZONE FOR THE PROPOSED PROJECT “DREDGING OF NAVIGATIONAL CHANNEL IN AN AREA BETWEEN MAZAGON DOCK SHIPBUILDERS LTD AND MUMBAI PORT”
Page 12 of 37
geomorphology mapping of the study area. The LISS-IV camera in IRS P6 is
a high resolution multi-spectral camera operating in three spectral bands (B2,
B3, B4). In the multi-spectral mode (Mx), a swath of 23 Km is covered in three
bands. The LISS-IV camera can be tilted in the across track direction thereby
providing a revisit period of 5 days.
Tide Tables are published by Survey of India, Government of India with
Prediction of tides at 44 ports including 14 foreign ports every year. 19 years
tide tables were used along with Navigation Charts from NHO, Dehradun for
finding Lowest Low Tide and Highest High Tide.
Bathymetry data from Navigation Charts published by NHO, Dehradun
are used for determination of LTL in the vicinity of project area.
1.5 Methodology
The cadastral map of part of Mumbai Municipal Corporation has been
used as the base map. The Geomorphology of the Coastal Zone has been
studied from the temporal medium resolution satellite data. In order to
prepare the local level map on 1:4,000 scale, the site has been inspected by
IRS Scientists in the last week of August 2016. Based on the geomorphic
units, the high tide line has been identified in the field and traced by field
survey using GNSS. The tide level observations were collected from the Tide
Tables. The highest high tide level and lowest low tide level for the past 19
years were determined from these tide tables.
As per the definition of high tide line, “The High Tide Line means the
line on the land up to which the highest water line reaches during the
spring tide”. There is a clear boundary between the areal spread of mudflats
and vegetation usually very much apparent. This boundary line coincides with
DEMARCATION OF HIGH TIDE LINE, LOW TIDE LINE AND COASTAL REGULATION ZONE FOR THE PROPOSED PROJECT “DREDGING OF NAVIGATIONAL CHANNEL IN AN AREA BETWEEN MAZAGON DOCK SHIPBUILDERS LTD AND MUMBAI PORT”
Page 13 of 37
the HTL line interpreted from the satellite imagery. On the other hand LTL is
defined as the seaward limit to which the waves recede during low tide.
In case of inland waters such as creeks and backwaters, the ICRZ
guidelines indicates that the development along rivers, creeks, creek lets and
backwaters has to be regulated up to a distance where the tidal effects are
experienced which has to be determined based on salinity concentration of 5
parts per thousand (ppt).
1.6 GNSS Surveying
The Trimble R5 GNSS receivers were used to conduct the surveying at
the project site. The survey involves three components namely, 1.
Establishing Base Station, 2. Control Survey for Village Maps and 3. Real
Time Kinematic Survey for HTL Demarcation.
Establishing Base Station
The survey involves establishing one base station for Static Survey.
The base stations were identified on stable locations with clear view of sky for
uninterrupted access to GNSS satellite signals. The control point with known
elevation was used as initial reference station. The base station for the project
site was established on firm ground and observed with static GNSS survey
from the known coordinates of the control point. The observations times were
fixed based on the length of base lines to obtain highest possible accuracies.
Static Survey
The conduct of Static Survey using GNSS requires two GNSS
receivers, one to be setup over the control point (with known co-ordinate) and
another one over a reference station whose coordinates and distance from
DEMARCATION OF HIGH TIDE LINE, LOW TIDE LINE AND COASTAL REGULATION ZONE FOR THE PROPOSED PROJECT “DREDGING OF NAVIGATIONAL CHANNEL IN AN AREA BETWEEN MAZAGON DOCK SHIPBUILDERS LTD AND MUMBAI PORT”
Page 14 of 37
the control point are to be determined. Both these receivers must record data
simultaneously. These known co-ordinates of the control point were fed and
fixed for processing of the logged data to accurately determine the co-
ordinates of the base stations.
Control Survey for Georeferencing Village Maps
The cadastral map pertaining to the project site was provided by the
client. The hard copy cadastral map was scanned and georeferenced with the
help of GNSS coordinates of boundary points provided by the client and used
for the preparation of local level HTL Maps.
Real Kinematic Survey for HTL Demarcation
Kinematic Surveying enables a very rapid survey of a number of base
lines in areas where there is good satellite visibility. At least, two GNSS
receivers are required to perform a kinematic survey. One receiver is
designated as the reference receiver and is set up over the Base Station. All
baselines are measured relative to this station. The other receivers, called
rovers, are moved in succession to trace and record the HTL on ground
through ground profiling.
Demarcation of HTL
Surrogate data such as coastal geomorphologic features identified
from the satellite imagery, indicators available on the ground and tidal data
were used to verify the HTL demarcated by Kinematic Survey.

2.0 STUDY AREA
2.1 Description of Study Area
The proposed dredging site is located in Arabian sea in the
navigational channel in an area between Mazagon Dock Shipbuilders Ltd and
Mumbai Port in Maharashtra State.
2.2 Field Verification Survey
The HTL was demarcated by physical survey in the study area as per
the guidelines provided by CRZ Notification, 2011 issued by MoEF&CC, New
Delhi. The position of HTL associated with wave runup at Highest High Tide
and geomorphic and topographic features such as ground elevation,
permanent terrestrial vegetation were considered for field verification of HTL.
In addition, geomorphic features such as berms, cliffs, sand dunes,
headlands, mudflats, were verified to demarcate HTL. Coastal protection
structures such as seawall, embankment, bunds, revetments were also
verified to demarcate HTL. LTL is also verified based on geomorphology
and bathymetric details available. The photographs taken during the field
survey are given below.
