Water fouling is a natural phenomenon that occurs due to sediment carried in river water in the water, i.e., water fouling. When river water enters the water area with sediment, the flow speed and sand carrying capacity of the water are continuously reduced along with the continuous increase of the water cross-sectional area, and the sediment is deposited at the bottom, so that the water area is deposited.

In essence, reservoir fouling is not only a reservoir volume, but also wasteful of building good natural objective conditions (dam sites) for the reservoir. At present, many reservoirs in China are built in mountains and basins, and the future reservoir building inevitably occupies some high-quality land and also has the condition of immigrants. The cost of the new reservoir is far greater than that of dredging and recycling the existing reservoir by counting the immigration compensation of the newly built reservoir, occupied land and the like. Therefore, advanced equipment and scientific and technical means should be applied to implement reservoir dredging engineering, so that the functions of the reservoir can be fully exerted, and the service life of the reservoir can be prolonged, which is quite necessary.
