The Department of River Research, affiliated with the Changjiang River Scientific Research Institute (CRSRI) of the Changjiang Water Resources Commision (CWRC) of Ministry of Water Resources (MWR), established in 1953, provides scientific and technological support in the field of river research for the protection, management, development, and regulation of CWRC. It is also a key supporting entity for the Key Lab of River and Lake Management and Flood Control in the Middle and Lower Reaches of the Changjiang River of MWR, and the maintenance unit of the Professional Committee for Protection and Restoration of Rivers and Lakes in River Basin of the Changjiang Technology and Economy Society.

The Department of River Research conducts research in several critical areas, including fundamental theories of river dynamics, channel evolution and management, flood control and disaster mitigation, engineering sediment, sediment resource utilization within basins, river and lake protection, ecological restoration, schistosomiasis control, smart water resource management, and institutional and policy frameworks for water governance. Over the past decade, the Department has led over 300 national, provincial, and ministerial-level research projects, including the National Science and Technology Support Program, the National Key R&D Program, the National Natural Science Foundation of China etc. These efforts have resulted in nearly 40 awards at the provincial and ministerial levels and numerous other recognitions for scientific achievement.

The Department of River Research has contributed to the development of dozens of planning and compilation work, including comprehensive planning, flood control planning, channel management planning, sand mining planning, and shoreline protection and utilization plans for the Yangtze River Basin. It has also undertaken the design of river regime control and bank protection projects for key segments of the middle and lower reaches of the Yangtze River, such as Jingjiang, Ma'anshan, and Zhenjiang-Yangzhou. Additionally, it has executed thousands of consulting and technical service projects, encompassing sediment management in engineering, flood impact assessments, sand mining evaluations, river and lake governance under the "River and Lake Chief System," water project planning approvals, reservoir operation, reservoir dredging, ecological protection and restoration of rivers and lakes, digital twin technologies, and water policy and regulation development. It also regularly participates in the supervision and inspection of water administration of CWRC.

The Department possesses the world's largest river physical model—the Changjiang Flood Control Model, with 8 experimental halls covering an area of over 100,000 m², providing an excellent research environment, state-of-the-art experimental infrastructure, and advanced monitoring and control equipment. Furthermore, the Department has developed several proprietary hydrodynamic and sediment numerical models, as well as an integrated digital platform for river numerical simulations.
