Managing sediment in river basins and waterways became a key point in water management. The continuous sediment deposition from the rivers and streams flowing to the reservoirs is today’s problem. When precipitation falls, the process of separating the soil grains and trying to transport them due to the energy possessed by the surface runoff occurs, leading to soil erosion and dredging. On the other hand, when the speed of the surface runoff that carries the soil and grains entering the lakes decreases, the potential energy that carries the sediments also decreases, leading to sedimentation. The size of settable and sediment particles varies according to the system and nature of the water. One of the main difficulties of hydraulic structures is accumulating sediment transport upstream of the structure. Hence, it is important to estimate these deposits’ amount and their negative impacts on these hydraulic structures to maintain their stability. There are many professional programs and software for estimating the productivity of sediments, such as the Soil and Water Assessment Tool (SWAT) and Artificial Neural Network (ANN).
