Abstract:: To explore the long-term exploitation of deep confined water in urban water sources in China, the concept and delineation method of rational water level for confined water were proposed. Taking the newly-built water source in Xiping County of Henan Province as the target area, the numerical model of groundwater was established according to the actual conditions of the study area. The groundwater level change under different scenarios was determined by groundwater numerical simulation method, and land subsidence of the study area was calculated by using the empirical formula. The amount of land subsidence under different scenarios, combined with the boundary of the designated water source protection area, delineated the rational water level of the confined water in the urban water source area of the study area. The results showed that while mining confined water, in order to prevent serious ground subsidence caused by the exploitation of confined water, the groundwater exploitation intensity of the newly-built water source in Xiping County should be controlled at 18 200-33 400 m3/d. Taking the G06 observation well as an example, the normal mining water level was 27.58 m, the restricted mining water level was 24.12 m, the prohibited mining water level was 20.34 m， and the threshold level of rational water level of confined water was 20.34-27.58 m.
