Abstract:
Sea level rise this now a global issue and phenomenon that be studied in implementation problem in coastal area. The study aims (1) Estimation sea level rise trend in Piai Island,, (2), Estimation innundation rate as sea level rise impact (3) to knowing change of shoreline in Piai. This research method survey with field measurements and the same secondary data of NOAA. Direct mensurements refer to biofisic data e such as slope beach, elevation beach, and widit of beach. Secondary data obtained by downloading online data such as sea level rise data, current model, and other online data. The result showed sea level rise in Raja Ampat Regian and Piai Island following linear type with averange increase is 8.7 mm/year. Based IPCC scenario so innudation area in Piai rookeries is 0.5-2.3 m or 40%. Piai Rookeries to show there shoreline change in every year (2015-2030) is 05-1.5 m.
