Abstract

Reasonable design of exploitation scheme is of great significance to the exploitation of groundwater resources and the avoidance of environmental geological problems. The study area is located in Chengde, which is a typical region along a river．Based on the clear regional hydrogeological conditions, a numerical model of groundwater flow is established. The rational well layout is calculated on the basis of the formula and mapping superposition. The optimal exploitation scheme and the exploitable resources of groundwater are obtained by combining numerical and analytical method. The results show that 29 pumping wells is along the river in 4 regions with the distance between wells of 150 m. The distance between the wells and the river is 25 m and the allowable exploitation quantity is 4.53×104 m3/d. Luan River has not only sufficient and stable groundwater supply but also a higher guarantee degree of water intake. Meanwhile, this scheme has little impact on the regional water environment.
