Modeling Sediment Accumulation at Kenyir Reservoir Using GSTARS3

An attempt was made in this study to predict the Kenyir reservoir sedimentation deposition processes at Terengganu, Malaysia. The purpose of this study is to determine the amount and location of sediment accumulated since the start of the Kenyir dam operation. The assessment was undertaken using GSTARS3 sediment transport model, which was integrated with GIS to display the output as sequences of grids. ArcView was used to convert the GSTARS3 model output to Arc View GIS grid format. The study successfully integrated GSTARS3 and ArcView models. The study demonstrates the ability of the adopted methodology to visualize the accumulated sedimentation during the operation period of the Kenyir dam.
