HYDROLOGICAL DISCHARGE DETERMINATION AND SEDIMENTATION ANALYSIS AT CIPUNAGARA ESTUARY, IN SUBANG

Coastal area is very dynamic. The sedimentation in estuary causes coastal morphological changes. Sediment which is carried by river flow will be acumulated in the estuary. Sedimentation phenomenon also occurs in Cipunagara Estuary, Subang, Indonesia and then causing the accretion. Due to this occ...
