Abstract

The research aimed to study the effect of groin application to erosion at the shoreline. The method utilized the bathymetry and topography data of north beach of Balongan, West Java. Modeling of the shoreline change due to groin installment used software called GENESIS. Based on analysis result, it is found that the significant wave direction comes from the southeast with significant wave height of 1,18 meters and surf zone width of 140 meters. It is concluded that at research area of north beach of west Java, I-groin with length of 70 meters and T head groin of 60 meters in long T-groin effectively overcome erosion and advance the coastline by 10786,62 m2 or in average 6,3 meters.

北爪哇海滩海岸线随Groin海岸保护结构的变化
本研究旨在研究应用丁坝对海岸线侵蚀的影响。该方法利用了西爪哇巴隆甘北部海滩的测深和地形数据。使用名为GENESIS的软件对腹股沟安装引起的海岸线变化进行建模。根据分析结果,发现有效波浪方向为东南方向,有效波高为1,18米,浪带宽度为140米。结果表明,在西爪哇岛北部海滩的研究区,长70米的I形丁坝和长T形丁坝中60米的T形头丁坝有效地克服了侵蚀,使海岸线平均前进了10786,62平方米,即6.3米。
