Abstract

Shoreline change is caused by longshore sediment transport which is the effect of nearshore wave induced current. Other causes are physical condition and coastal geomorphology such as bathymetry contour and coastal protection structure. This paper studies shoreline change in Belawan Port which is located in North Sumatra, Indonesia. In study area, breakwater is proposed to protect the navigation channel of Belawan Port from sedimentation problem. The objective of this study is to predict shoreline change around Belawan Port due to the existence of breakwater by using one-line model, GENESIS. GENESIS is used for predicting the behaviour of shorelines in response to coastal engineering and/or beach replenishment activities that may affect long shore sediment transport. The input of the model are bathymetry contour and shoreline position, waves characteristics (height, period and direction), median sediment diameter (d50), and structure position and its estimate permeability. The output of the model is the change of shoreline position after a period of time. Shoreline change around Belawan Port has been analysed under the effects of existing breakwater. The existence of breakwater can change the natural balance of sediment transport and affect the shoreline change that occurred.
