CONSTRUCTION OF PENGAMBENGAN FISHING PORT ON WEST BALI ISLAND AND ITS DOWNCOAST EROSION

Abstract

At Pengambengan, facing Bali Strait in Bali, Indonesia, predominant northward longshore sand transport was obstructed by the construction of fishing port, resulting in severe sand deposition inside the fishing port as well as downcoast erosion. Field observations were carried out two times in May 5 and August 8, 2002. On the downcoast, seawall fell down and scarp was formed continuously due to severe erosion. In order to improve the present condition, it is required to take fundamental measures such as sand bypassing instead of local optimization of the eroded coast using structural defence.
