Founded in 1956, the Department of Sediment Research is mainly engaged in the sediment problems in rivers, reservoirs and estuaries, and soil and water conservation. The research fields cover fluvial processes and river training, reservoir sedimentation and its optimum operation, estuary sediment and its training, mechanism and monitoring and restoration of soil erosion, sediment problems in water-related projects. The department has the Key Laboratory of Sediment Science and Northern River Training of the Ministry of Water Resources, and the Research Center of Soil Conservation Ecological Engineering Technology of the Ministry of Water Resources. The Department has 4 large laboratories, with a total construction area of 14,000m². The department has two 5-star certificates for soil and water conservation program compilation and monitoring and evaluation. It undertakes the daily work of the Sediment Committee of the Chinese Hydraulic Engineering Society and the Scientific and Technological Cooperative Working Committee of the Chinese Society of Soil and Water Conservation, as well as the edition and publication of the Journal of Sediment Research.

The Department has 7 research sections and 57 employees, including 33 professor-level senior engineers, 15 senior engineers and 7 engineers. Among them, 49 people hold  doctoral degrees and 5 people hold Master's degrees.
