Abstract:
Coastal zone plays as majority crucial roles to the world's population and industrial
activity. Both natural and human factor caused erosion and sedimentation. Kuala
Terengganu coast presents an important area for tourism, fishing and industrial activities.
However, since 1980s this area was affected by erosion and sedimentation. In this study,
numerical LITP ACK model was applied to model the cross-shore profile changes along
the study area of Teluk Ketapang beach to Seberang Takir for about 5 kilometers.
LITPACK is part of the generation of DHI software based on the MIKE Zero concept. It
is a software package for simulating non-cohesive sediment transport in waves and
currents, littoral drift, coastline evolution and profile development along quasi-uniform
beaches. In this study, LITPROF module was used to describe cross-shore profile changes
based on time series of wave event. This module was used in predicted the coastal erosion
using different wave height and water level. The model is based on the assumption that
long shore gradients in hydrodynamic and sediment conditions are negligible and that the
depth contours are parallel to the coastline. Thus the coastal morphology is solely
described by the cross-shore profile. Water level, wave data and sediment characteristics
was taken from Royal Malaysian Navy and previous researcher respectively. These data
was the inputs for simulating the cross-shore profile changes. At the end of the thesis,
LITPOF module was successfully been used to study the cross-shore morphology
changes along Kuala Terengganu coastal. The increasing of wave height and water level
had given different impact whether erosion or accretion. Erosion higher for increased in
water level factor compared to the increasing of wave height factor. This is useful to
make a decision in coastal zone management.
