Caused shift voltage degradation and agradation on river

This study aims to find out the degradation and agradation along the river segments and to determine the occurrence of sedimentation processes. Sediment that moves in the river as suspended sediment (suspended sediment) in flowing water and as a base load or (bed load). shift or roll along the bottom of the channel and move in the form of a jump (saltation). this causes eroded surface erosion and basic sediment (bedload). which will accumulate into degradation and aggradation, make the water channel shallow shallow sediment will settle in the sloping river with the speed of water flow that is slow, the ability of the transport itself is affected by discharge, average flow velocity, slope, shear stress. The case study was carried out on the 4 km long goitre river which is a sub-critical quasi-steady stream with the Froude number <0.6. Samples of basic sediment material with variations in grain diameter d35, d50, d65, and d90 in grain size analysis are used for calculations. The process of degradation and agglutation of the riverbed is known by the calculation of sediment discharge using the Meyer-Petter & Muller method.
