| description | Sarawak River estuary faced critical erosion by ocean surface wave
nowadays. Not only exposed to high energy wave condition from South China Sea,
but also due to navigation channel. Hence, wave models are needed to control and
then overcome this problem. Using the SWAN (Simulating WAve Nearshore) wave
modeling, the physical wave parameters were investigated to determine the wave
condition nearshore. This investigation is carried out to predict the wave generation,
refraction and energy dissipation at Sarawak River estuary with dredging and
reclamation bathymetry, and using the previous data of local wind and wave. The
bathymetry map is digitized in SURFER where dredging and reclamation is
visualized to view the bottom data. The wave model was developed for Annual,
Northeast Monsoon and Southwest Monsoon wave condition. Design waves are
analyzed using statistical method of short term and long term analysis. Short term
analysis is presented by significant wave height of average height of the one third
highest waves (H1/3), while, long term analysis comprises of extreme value from
Gumbel and Weibull statistical distribution analysis. The outputs from this model are
significant wave height (H
s
), mean wave period (Tm01) and wave direction (Dir) for
each chose location. The H
s
, Tm01 and Dir are different for each location. |
