Monitoring Total Suspended Solid Concentration and Shoreline Dynamics Using Sentinel-2 Imagery in 2015-2021

Human activities in the Juwana Estuary impact increasing sedimentation, including industry, fish processing, ponds, and settlements. Increased sedimentation every year can lead to formation of new land. In long term, will shoreline changes due This study aims determine Total Suspended Solid (TSS) concentration values River Estuary. be indicated based on water turbidity TSS values—an effective method for observing coastline using remote sensing. The data this uses Sentinel-2 imagery. processing algorithm Laili, Liu, C2RCC. results C2RCC show best regression between image situ with an R2 0.721 compared other algorithms. 2015-2018 average value decreased by 2.303 mg/l. Processing largest reduction 12.466 mg/l Coast. 2018-2021 shows decrease 4.447 mg/l; decrease, a 19.3 mg/l, is Batangan extracted from Normalized Difference Water Index (NDWI) algorithm. were dominated abrasion, covering area 35.2348 ha maximum distance 143.78 m. 10.28224 53.23 It interpreted that indicates causing increased abrasion around coastline.
