Sediments are the result of erosion, either in the form of surface erosion, trench erosion, or other types of soil erosion. The increase in the percentage of sediment in the reservoir which increases rapidly at any time, causing siltation of the reservoir and influencing the reservoir capacity and service life of the reservoir. In this paper, we will discuss the volume of sediment deposits, sedimentation rates, sediment distribution, and estimated service life of reservoirs in the North West Brebes district. Sediment sediment volume that settles at each marked elevation is reduced by the volume of reservoir reservoir. The sedimentation rate that occurs is based on the volume of sediment that settles every year. The service life of the reservoir is marked by a decrease in the dead reservoir. The volume of sediment that occurred in the Balikayu dam in 2016 reached 8.7965437 million m3. The sedimentation rate that occurred ranged from 1.2566491 million m3 / year. The age of the reservoir is 85 years, but the measurement results move faster. By comparing the actual sedimentation rate with reservoir planning data, if there is a suitability it is necessary to carry out maintenance and if a faster estimate occurs with planning it is necessary to handle the sediment that occurs. |
