Alternative planning for safety building of namrole beach in South Buru regency-Maluku

Abstract

Namrole coast faces erosion problems due to changes in the coastline because of the settlement is near to the coast where the buffer zone has not been planned. Thus, during the wave season, the settlement is within reach of wave run up. The results of the analysis of coastal building selection were carried out by alternative study methods and modeling of coastal buildings using Coastal Engineering Design and Analysis System (CEDAS)-NEMOS application. From the several models of beach building modeled, Seawall was chosen as a coastal protection building with the design characteristics of the foot depth at 0.5 m, wave height rupture at the end of the building 0.4 m, seawall elevation 2.8 MSL and minimum diameter of building foot protection stone of 22 cm.
