Characterizing Coastline and Sediment Interaction in The North Coast of Java using Satellite Images

Abstract

The large amount of sedimentation process caused rapid changes in the coastline presented by capes form in the coastal area. To characterize coastline and sediment interaction used coastline change analysis, hydrological and vegetation indices using Landsat imagery. Accordingly, we successfully characterized the Cirebon coastline into four categories: abrasion, accretion, abrasion to accretion, accretion to abrasion. The NSM range values -1.123,67 m – 1.026,19 m. The highest abrasion (EPR, LRR, WLR) is 33,18 m/y, 31,16 m/y and 31,16 m/y. The highest accretion (EPR, LRR, WLR) 30,3 m/y, 29,16 m/y, 29,16 m/y. The results of the hydrological index parameters show that humidity levels vary from drought (low humidity) to high humidity, but in the eastern part it includes the water surface. The results of the vegetation index parameter show that the vegetation level was dense, moderate to sparsely grown with vegetation, canopy cover varying from low to medium. Clay material (mud) has impermeable properties, so the study area is dominated by accretion because there is large supply sediment from rivers that enter the sea. Based on these data, it can be concluded that the characteristics of the beach are divided into muddy beaches, and coastal structures such as harbor.
