[0002] Among numerous hydraulic engineering maintenance work, dredging is a basic and key task. With the sediment carried by the water flow depositing, thick silt layer is gradually formed on the water bottom, which not only reduces the effective volume of the water body and hinders the smooth flow of the water, but also can become a gathering place of pollutants, causing negative impact on the water environment. In severe cases, silt accumulation can cause slow or stagnant flow of the water body, affecting the survival of aquatic organisms, and even causing flood disasters. Therefore, regularly removing the silt on the water bottom and keeping the water body unobstructed and the water quality clean are crucial for maintaining the normal operation of the hydraulic engineering.
