Damage and loss of land resources due to improper land management tend to increase erosion. It will affect the production, ecological, and hydrological functions in the upstream watershed area. However, sedimentation that occurs due to erosion often affects the practical life of the dams. The purpose of this research is to estimate erosion and the distribution of Total Suspended Sediments (TSS) geospatially from Landsat-8 imagery data in 2015 and 2019 for Krueng Pase Watershed. The considerable erosion that occurred in 2014 was 117,987.71 tons. While the erosion that occurred in January 2015 was 18,624.45 tons, and the erosion in August 2019 was 6,672.06 tons. The results of the TSS distribution using algorithms in 2015 obtained the largest total suspended sediment with a value >17.15 mg/l found on the coastal, riverbanks and the smallest TSS with a value of ≤12.73 mg/l found on the upstream area. The TSS were found on the coastal with a value of >16.05 mg/l, and the smallest TSS >12.92 mg/l found on the upstream area in 2019. Information on the distribution of total sediment is a consideration in the application of the eco-hydrology concept as a short-term solution in water management.
