Abstract

Ci Manuk Flow Area is one of the river basins in Java Island. The Ci Manuk Delta changed from 1963 to 2002. Changes that occurred in the Ci Manuk delta were moved by extensive accretion. The reason for choosing Ci Manuk Delta is because the Ci Manuk flow has a high sedimentation rate compared to other flow areas, besides that, Sumedang Regency has built a dam to hold the sediment flow and repair floods. How this is done as a problem and research can be done to determine the delta-forming factors and changes in the delta region that occurred temporally from 2002 to 2018 after the dam was built. The method used in this research is spatial analysis and quantitative descriptive analysis. Spatial analysis is used to describe the spatial change in the temporary area and quantitative descriptive analysis is used to explain the results of the calculation of changes in delta area. The results of this study are the dynamics of delta changes that occur in the west are dominated by the addition of delta (accretion) with an area of 522.3 ha and undergo a change in shape from cuspate to birdfoot. The factors that support the addition of the area comes from internal factors, namely the high value of sediment and the low external factors originating from the marin.
