N2 - Construction of dams in the upstream area will lead to changes in flow water, sediment output in the downstream area and change nutrients entry into estuatries then affects chl-a (Chl-a) concentration. The purpose of this paper is to investigate the influence of the functioning of the dam Jatigede in Sumedang District towards the condition of total suspended solids (TSS) and chl-a (Chl-a) concentration in the sea water around the mouth of the Cimanuk River. In this study, we used multi-temporal Landsat 8 OLI/TIRS imagery to determine the spatial pattern of TSS during the time before and after the functioning of dam Jatigede. The results showed that after the Jatigede Dam operated, the distributions and amounts of TSS concentration > 80mg/l tends to reduce, especially at the water areas close to the coast and the Cimanuk river discharge no longer significantly affects the spatial distribution of TSS concentrations. The watershed discharge also affects the distribution area of Chl-a 0.5-1 mg/m3 which tend to decrease in the water nearby to land.
