Greater portion of fourteen kilometres of coastal area of Senggarang area is expected to be flooded by sea water due to constant.ard gradual erosio,t process which will eventually eats up the land. If this anticipated event happens, it will render thousands of people livirtg in that area homeless, and also lose their land for agricultural purposes which is the major source of their livelihood. A study on the area of erosion has been carried out for identifying the problem, collecting the data and finding the solution to prevent erosion in the years to come. It was found that the main reason of occurring erosion due to the soil that forms the coast is soft which cannot stand to the wave attack even though mangroves are there. An analysis based on CDAS (GENESIS) has been done as well which yields best placement and selection of beach structures to anticipate the current and future erosion where a combination of two beach strr.tctures (breakwaters and groins) b selected to be implementeri in the area of erosion. Croins are placed at tvvo sides of every estuaries which steak out into the sea as long as i50 m, while each unit of breakwater is provided 300 m length and placed perallel with the existing shoreline and 150 m atvay from the shoreline with gab of 100 n each cther.
