The purpose of this study is to know shoreline change with the various width between breakwaters until choose the best one to protect infrastructures such as roads, housing and to support fishery and economy sector without cause another problem for around it. Analysis performed within this research are tides fluctuation analysis to estimates design elevation guidance, wave forecasting using series of wind data in ten years (1997-2006) from Meteorology and Geophysics Biro Fatmawati Bengkulu to examine predicted wave heights and periods, and finally analysis of shoreline change with Bengkunat fishery port construction using GENESIS software. From this analysis is decided the erotion dots in port pond and is made a prevention concept with mangrove concervation, increase revetment and sand by passing, beside that, is needed recomendations to treath Bengkunat Bay Beach comprehensively.
