Modelling Shoreline Changes in a Port Area at Southern Java Due to Detached Breakwaters

EasyChair Preprint 14807

Abstract

Detached breakwaters, commonly used to mitigate coastal erosion, can lead to significant sedimentation issues when employed as protective structures near ports. These issues often result in tombolo formation, which can severely disrupt port operations. This study examines a case at a port in southern Java, where the use of a detached breakwater caused a complete operational shutdown. Through simulations conducted with GenCade, the sedimentation process was modelled to identify the conditions leading to tombolo formation. Based on these findings, alternative design solutions are proposed to prevent similar problems in the future. The results highlight the need to avoid the use of detached breakwaters for port protection, emphasising that this approach represents a fundamental error in coastal engineering. More suitable coastal structures should be encouraged to ensure the effectiveness of port operations.
