Abstract

Abstract: The management of sedimentation in a reservoir offers a comprehensive assessment of the sediment transportation and erosion processes. Understanding sedimentation is helpful for managing reservoirs. Dam silting volumes can be evaluated by bathymetric surveys. The Arzengarzen earthen dam in Budgam district of Jammu and Kashmir had two surveys conducted, and the data are available. Initial data regarding the amount and variability of silting as well as the mechanism of sediment deposition are provided by the measurements. The average annual specific sediment output of the Arzengarzen earthen dam watershed is projected to be 2851 t m 3 /yr based on measurement results. The average yearly volume of confined sediment varies, ranging from 2300 m3 in 2010 Over time, the sedimentation rate rises from 0.20 to 0.43%. The findings show a relationship between the presence of soils on steep slopes and particular rates of erosion. The only source of income in the area (Agriculture )is at risk due to the strain that the area's population has placed on the land through overgrazing and plowing, which has caused increased erosion and further deterioration.
