Introduction
Malaysia have a coastline approximately 4809 km long where it is made up of 1972 km in
Peninsular Malaysia, 1035 km in Sarawak and 1802 km in Sabah that include Labuan
(Bird, 2010). More than half of the coastlines are beaches while another less than half is
mostly covered by mangrove area. It has been estimated that some 30% of the coastline are
is
subject to varying degrees of erosion (Ong, 2000). In Malaysia, most of the main city
located near the coastline area which indicates that the coastline area had played an
important role in supporting local communities.
Malaysia coastal areas had been home to
impacts of
more than 60% of total population of Malaysia and much more sensitive to the
2000). The coastline area
climate change (Ministry Of Science, Technology and Inovation,
can provide direct and indirect value which is important
in the growth of industrial
activities such as fisheries, tourism industry, oil and gas production and agriculture.
However, the areas that cover along the coastal area are usually subjected to erosion and
accretion in recent years. National Coastal Erosion Study from November 1984 to January
1986 study results indicate that out of the country's coastline of 4809 km. about 29% or
1,380 km was facing erosion (Department
of Irrigation

and Drainage. 2012a). Coastal
that live around the coast. Hence. where
those communities are developed at the back of coastal dunes, it is of uttermost importance
to assess the erosion and flooding risks, for which it is necessary to quantify the coastal
dunes vulnerability (Sancho et al., 2012). There is very few of coastal research had been
conducted in Peninsular Malaysia but there a little in Sarawak which are at Miri on 2010
and Final year project at Sematan on 2012. There is no research had been done yet at
beaches along Kuala Santubong, Sarawak.

Sarawak experiences
two monsoonal
changes. The Northeast
Monsoon

occurs between November to March and the Southwest Monsoon usually occurs
May or early June and ends in September. Sarawak coastal areas were exposed to South
China Sea. The erosion in coastal areas in Sarawak might be due to sediment deposition,
wind and wave actions, river flows, tidal change, sea level and climate change. However,
the biggest factor that affecting the erosion is wave action. The wave strength is usually
fetches and strong wind will create bigger and
controlled by it fetch and wind speed. Long
more powerful waves that have more erosive effect.
It is very important

particularly at beaches of Kuala Santubong which is still not yet investigated
these three proposed objectives:
1) To determine geomorphological
changes at Kuala Santubong.
2) To identify the vulnerability level of the coasts at Kuala Santubong. and
3) To determine the awareness level of local community to vulnerability of the beaches.

Literature
Review
2.1
Kuala Santubong
beaches
Kuala Santubong beaches are located at coasts along Kampong Pasir Pandak. Kampong
Pasir Panjang, and Kampong Tanjung Batu. This area is located approximately 20 km from
Kuching City Centre. All the villages are place adjacent to each other.
There are four
beaches at Kuala Santubong, that are Pasir Pandak beach. Pasir Panjang beach, and another
2 beaches besides Pasir Panjang beach. Kuala Santubong beaches cover approximately
1.45 km in length for coastline.
However, the Pasir Panjang beach had been developed into recreational
park and called
D'Cove Pasir Panjang Family Park. D'Cove Pasir Panjang Family Park is another project
developed by Pelita Holdings Sdn Bhd (PELITA, 2013). It is believed to be designed as a
unique recreational
and resort hub away from Kuching
city centre that
caters for
recreational and social needs of local residents as well as to allow tourists to appreciate the
beauty of our natural landscape.
Apart from that, on year 2005 government had built rock revetment at Pasir Pandak beach
under Coastal Erosion Control Project at Kg. Pasir Pandak, Kuching. Sarawak. The rock
revetment construction had been constructs by Kejuruteraan Janje Sdn. Bhd. and had been
complete on 20 April 2005 (DID, 2012b)
2.2
Coastal geomorphology
Coastal zone are defined as the geomorphologic
area either side of the seashore in which
the interaction between the marine and land parts occurs in the form of complex ecological
and resource systems made up of biotic and abiotic components coexisting and interacting
with

communities

(United

Programme, 2008). There are a large number of residents living near the

coastal area and a lot of people go to the coastline
activities. Most

seaside recreation. They are wondering how they
features
such as beaches,
geomorphology
dunes
and cliffs while walking
along the shore. Coastal
deals with the shaping of coastal features and the processes that occur on
them and the changes that happen.
The coastline is subjected to erosion or accretion and
the changes in sea level.
2.2.1
Beaches
Beaches can be found at all sedimentary
shorelines that exposed to waves. Bird (2008)
defined beach as an accumulation of loose, unconsolidated
sediment that range in size from
very fine sand to pebbles, cobbles and boulders which often with shelly materials on the
shore that had most dynamic physical system. Mostly the beaches will experience gaining
or losing of sediment. Some of the beaches might consist of sediment in transit which is
the sediment that had been migrates along the coasts.
2.2.2
Beach sediment
Beach sediments, it usually consists of various sizes of sand or gravel particles and it
contribution in beach dynamics depends on the sizes. To describe the beach, usually it will
consider the size of the sediment. Generally, the smaller the sand sizes, the flatter the
beaches. However, beaches are sorted based on wave energy. The most important process
of sediment transportation is a litthoral drift or beach drift that cause by oblique approach
of waves onto beaches. Beaches will become steeper, higher and better sorted at high wave

energy. While, at the low energy wave, the beaches had gentler gradient, finer and less
sorted. It also had less erosion due to convergent long shore currents bringing in beach
sediment. In addition, sediment in active beach system can be derived from various factors
such
as erosion

of upland
by rivers,

erosion of older beach and shoreface deposits and erosion. However, in
recent decades, many beaches had experience
human activities.
erosion or deposition
Bird (2008) said some beaches
(accretion)
have been artificially
due to
nourished
or
replenished, especially in a seaside resort.
2.3
Coastal erosion and accretion
Coastal erosion occurs when the beaches experience loose sediment alongshore. offshore
or to hinterland instead of receiving sediment from various sources. Malaysia had two
different physical
formation,
the mangrove
and nipah-
fringed mud flats and sandy
beaches. The mechanism of coastal erosion of mud coasts is less understood compare to
sandy coasts. Based on National Coastal Erosion Study 1986. Malaysia's
shorelines are
classified into three categories of erosion. It is depend on the threat it will cause to the
shore and the facilities around. The three categories are:
Category 1: The critical erosion areas where the facilities or infrastructures are in greatest
danger.
Category 2: The significant erosion areas where the facilities or infrastructure are expected
to be in danger condition within 5 to 10 years if there is no action taken.
Category 3: Acceptable Erosion areas where there is no danger to economic loss if left
uncheck.

distribution of eroding of coastal in Malaysia in 1985 and 2010 can be seen

Based on the Table 1, it shows that around 3.5 per cent of Sarawak coastal in 2010 (Tang
& Lee, 2010) had been eroded which is increase by 0.5 per cent compare in 1985. The
table also show the addition of one site that eroded. Furthermore, the most cause of beach
erosion at Malaysia is waves. Waves generate by wind or tides can cause erosion by
transport the sediment away from shore. The loss of sand causes the beach to become
steeper and lower in elevation. Longshore transport is also responsible to the sediment
movement as it is in direction of wave. During monsoon, the erosion becomes worsening
when high water level coincides with storm events (Abdullah, 1992). The increase waves
breaking force cause the sediment loss to increase.
Erosion also occur due to man's
activities such as sand mining, urbanization, tourism and recreational activities, industrial
production and many other human activities. Moreover, Abdullah (1992) stated that poorly
sited coastal structures
can also cause erosion as it can interrupt longshore

Coastal vulnerability
Vulnerability
is a measure of the extent to which any human or natural systems can cope
with the adverse effects. However, vulnerability is defined as the degree to which a system
is susceptible
to, or unable to cope with, adverse effects of climate change. including
climate variability and extremes (Intergovernmental
Panel on Climate Change, 2001). It is
a function of system sensitivity to the changes in climate which include beneficial and
harmful effects, the degree of exposure of the system to climatic hazards and adaptive
capacity which is the degree to adjustment in practices and processes or structures
can
moderate the potential for damage. The relationship of the three components is illustrated
in Figure 1

2.4.1
Exposure
Exposure quantifies the intensity or severity of physical environment conditions that drive
changes in the state of the biophysical system (Alino el al., 2013). The major element in
vulnerability is exposure which is often to be mention explicitly or implicitly. The interface
is form between physical environment
and vulnerable
entities. To describe exposure,
information on hazard event and on the existence of elements that are exposed is use.
Waves are natural process that can cause coastal erosion. While, wind is the important
agent for waves (Scheffers el al.. 2012) as it blow on the ocean surface which create the
waves. Strong waves may cause erosion on shore.
A strong of sudden break of waves
might cause severe erosion on the shore as it can erode the rocks and causes sedimentation
to occur. The band at which the waves break is called the surf zone which is the area of
violent movement. The breakings waves disperse the energy by generate extreme currents
that end in final uprush to the beach.
The turbulence
lifts the sediments off from the
bottom of the sea then will be transport by local currents. Malaysia is influence by two
monsoon regime, the Southwest
Monsoon from late May to September and Northeast
Monsoon from November to March (Department
9
of Malaysian
Meteorological,
2013).
Monsoon might cause severe erosion due to some storm events. Sea level rise rate had
increase resulting of climate change. The greenhouse gas in the atmosphere had resulting
of global climate change to occur. The sea level also rises due to the oceans warm which
lead to the density decrease and thus the volume of ocean increase at constant mass.
Around Malaysia coasts, there is fall in sea level with the mean rate of 1 mm per year for
over 5000 or so years. It is believe that Global sea level change over past 50 years is to be
+ 2.4 ± 0.9 mm y-1 (Ong, 2000). The physical impacts that can be seen due to sea level rise
are coastal erosion, flooding and increase saline intrusion inland. The sea level will result
in low-lying coastal and riverine to flood permanently
which will also cause erosion on
sandy beach and muddy coastline.
2.4.2
Sensitivity
Sensitivity is defined as measures that describe the system's present state for specific
properties that respond to exposure factors arising from changes in climate (Alino et al.,
2013). It may also describe as degree at which a natural or human system had directly or
indirectly affected by changes in climate changes. If a system is affected, it should be
considered as sensitive to climate change.
2.4.3
Adaptive Capacity (AC)
Adaptive capacity is defined as measures that characterize the ability of the system to cope
with impacts associated with changes in (Alin
et al., 2013). It describes the ability of
natural or human systems which associate with planning area withstand changes in climate
with minimum disruption.

Assessment
Vulnerability
(VA) tools
there are three components that is necessary to be obtains. The
To measure vulnerability,
three components are exposure, sensitivity and adaptive capacity. The coastal VA tools
(Alin

2013). There are various tools that can be used in measuring

However, for coral triangle countries there are three tools that had been recommended. The
tools are Integrated
