“…Several physical aspects were analyzed, including ow or drainage density, morphological aspects of the research area, and land use patterns. Drainage density (DD) is closely related to the distribution of sediment in the nearshore zone at the research as the medium for transporting sediment (Aldharab et al, 2019;Smith, 1950). While the consideration of land use determines the type or amount of sediment that will be transported through channels or drainage.…”

Various environmental processes as impacts of urban areas related to coastal dynamics require continuous monitoring using the Geographic Information System (GIS). Among such consequences, the spread pattern of suspended sediment in urban coastal areas indicates urban flood risk. This research aimed to determine the spread pattern of suspended sediment in the urban coastal area of Kendal Regency, Indonesia. The primary research method employed ENVI to analyze the sequential band-ratio from Landsat 7 TM to Landsat 8 OLI/TIRS satellite images. The results show that the distribution patterns effectively use band 3/2 of Landsat 8 OLI/TIRS with ca. 0.1 higher for the DN value compared to the band 4/3. This finding indicates different cases in other regions that mostly enhance the band ratio of 4/3 – sequentially match with band 3/2 in Landsat 7 TM. By receiving clear visualization from a band ratio of 3/2, the potential major distribution of suspended sediment was seen in the northeast during the west-east transitional season. However, the East-West's transitional season shows the sediment's circulation at certain points that could become the potential benchmark locations for the siltation occurrence because of sediment concentrations.
