Abstract:Lack of reasonable and scientific planning of well layout is one of the most important reasons for the imbalance problem of groundwater supply and demand in the north irrigation districts of China. Baojixia irrigation district was used as the study model and based on its comprehensive groundwater resources, the types of groundwater development and utilization were classified. According to water supply and demand balance analysis under both sufficient insufficient irrigation conditions, the various schemes of groundwater extracting scale were figured out. A reasonable groundwater mining scale was determined based on the numerical simulation of groundwater to reduce the shortage rate of irrigation water and to balance the extraction and supply. Two methods, namely traditional method and GA optimization method, were applied to calculate the number of pumping wells, single well irrigating area and distance between two wells so as to determine a reasonable layout of well distribution in the irrigation district. The results showed that in the second scheme not only the less change in the groundwater level is obtained, but also extraction almost equals to infiltration of water and the water shortage rate is controlled in around 1%, and subsequently a sustainable groundwater utilization will be realized. According to the current number of wells, additional 53 wells should be drilled in the highland and the 242 wells should be reduced in the lowland in that irrigation district.
