Abstract: Based on the sustainable development concept to consider both preventing groundwater overexploitation and stabilizing winter wheat yield, the region with serious groundwater overexploitation in the Hebei Plain to the south of Beijing and Tianjin is selected as a case study in this investigation, from the viewpoint that multi-water resources allocation must be implemented for irrigation during the winter wheat growing season. Combined with the utilization of flood storage and detention areas after the “23·7” catastrophic flood in the Haihe River Basin, a preliminary discussion was conducted on the role of using flood storage and detention areas to construct surface regulating reservoirs from the following three aspects, i.e., the utilization of rain and flood resources, the utilization of domestic sewage resources, and the requirement of storage capacity for transbasin water diversion projects.
