COASTLINE CHANGE MEASUREMENT AND GENERATING RISK MAP
FOR THE COAST USING GEOGRAPHIC INFORMATION SYSTEM

KEY WORDS: Coastline, Chart datum, Geographic Information System, Risk map
ABSTRACT:
Information on the pattern, rhythm and long-term trend of shoreline dynamics is vital to managing the coast,
especially in mapping risk areas and in establishing the width of construction setback lines. Unfortunately, such
data are often missing or where present of doubtful quality. In this paper, we share our experience in mapping
coastline change in Singapore, using geographic information system (GIS). Most important before embarking on
measuring coastline change is defining the coastline and deciding on a working definition where this line can be
established on the ground, on maps or other sources of data. Complications arise where the coastline is extracted
from different data sources to detect changes. In Singapore, coastline is defined is 2.515 m chart datum and this
line which theoretically separates land from sea is shown on cadastral maps.
The East Coast Park of Singapore is selected to illustrate the different techniques in measuring coastline change
using GIS. Techniques include setting up a series of profile lines monitored and analyzed in GIS over a decade to
detect changes, and using GIS to generate the 2.515 m chart datum line from a dense network of elevation points
collected on the beach. Maps showing various rates of shoreline erosion are then derived and finally a Risk map
for the coast generated.
1. INTRODUCTION
Information on coastline change from seasonal to longer term
trend constitute an essential and vital input in any coastal
management plan, so that areas of potential loss to erosion
can be identified and appropriate land use planning adopted.
Unfortunately, such information is lacking and, where
present, often of doubtful reliability. In Singapore, additional
problems are encountered: the coastline is often «40 years
old, created after land reclamation and still undergoing
changes towards equilibrium. Along many coastal sectors the
retreat has been planned and many beaches have been
nourished to slow down shoreline retreat and maintain
popular beaches. Information on beach management and the
amount of sand used for nourishment is usually not available.
Hence, interpreting coastline change under such
circumstances is difficult.
A proper understanding of coastal processes in general and
the local history of land reclamation is required to interpret
the changing coastline. A retreating coastline may not be of
concern as it may be planned. On the other hand, a stable
coastline maintained by nourishment should be of concern.
Different sectors of the ECP show diverse behavior, with
some stable while others receding or advancing. This spatial
pattern of different rates of erosion and accretion provides
the basic information for micro management of the coast.
Emplacement of canal structures and additional breakwaters
has also changed the sedimentation pattern. All these have
made interpreting coastline change even more difficult.
Despite this, careful analysis of the data would still yield
useful information on erosion hazards and risks for
development. Shoreline management is not an exact science
and may entail a series of responses as unanticipated
problems emerge from time to time. When accurate
information on shoreline dynamics is lacking, it may be
490
wiser to adopt a precautionary principle in management.
Sometimes, facilities are constructed in a high risk area for
temporary use and this causes misunderstanding when not
properly explained. Different types of land use strategies
require different types on erosion hazards. Data on seasonal
coastline change is used to establish the width required to
create a buffer zone where the shore can retreat and recover
unimpeded. Longer term change will aid in land use planning
by establishing the highly dynamic and sensitive areas that
should not be developed.
2. MEASURING COASTLINE CHANGES:
CONSIDERATIONS
Important questions that need to be addressed in coastline
change studies include why coastline change is measured,
what is being measured and how the measurement is carried
out (Teh et al, 2005). It is important to understand the
reasons for measuring coastline change and the accuracy of
measurement so that the results derived can be properly
applied for planning purposes. Short-term changes have less
value for planning compared to long-term changes. On the
other hand the latter may not capture the seasonal changes
provided by the former which may be critical. If the reasons
for measurements are understood, this will help towards a
suitable definition of the coastline and the choice of
techniques to be employed. Past studies have used different
datum for measuring coastline change. The popular datum or
feature used includes a legally defined coastline which varies
from country to country, MHWS, vegetation line, seaward
foot of coastal dunes and coastal scarp. Different values are
obtained with the use of different datum or coastal features.
Longer term coastline changes usually use the oldest reliable
topographic map as a baseline whereas short term changes
