It has the right to grant bachelor's, master's and doctoral degrees, and has a postdoctoral mobile station to form a field of hydrology and water resources and environment. An important platform for complete scientific research, technology development, personnel training and academic exchange in engineering and agricultural water and soil engineering. In the context of the global water crisis, aiming at the shortage of water resources, frequent flood disasters and increasingly serious water pollution in the arid and semi-arid regions of northwest China, we will track the frontiers of international disciplines and give full play to the advantages of cross-disciplinary integration. Fundamental and applied basic research on key scientific issues of water resources protection and efficient use, environmental and ecological protection, and strive to enter the international advanced ranks in the aspects of water cycle mechanism and water environmental protection and ecological restoration, water source water quality improvement technology research in arid and semi-arid regions; The policy of “openness, mobility, competition, and unity” actively carries out cooperative research and academic exchanges, continuously improves the scientific research level of water resources and environmental ecology in the northwest, and provides scientific decision-making basis for the sustainable development of social economy in the northwest region.
