Description
Summary:The recharge source of groundwater is an important part of groundwater circulation. Controlled by geological structures, the distribution of groundwater in bedrock area is complicated. The study on the source of groundwater in bedrock has guiding significance for the evaluation of water source site and groundwater exploitation. By analyzing the model of water-rich zone based on remote sensing information, and according to the groundwater dynamics, major ion concentration, velocity and direction of groundwater flow, pumping and water level data of water source site, this article studies the source of groundwater recharge of Barakan Water Source Site(BWSS) in front of Kuruktag, northwest of China, and analyses the reasons for the abnormal change of the total water yield and the drawdown of the well. The results show that the groundwater of the water source site comes from the Aggregate Reclaiming Plant(ARP) about 6.5 kilometers northwest of BWSS. The ARP water pumping is the main reason of the abnormal change of the total water yield and the drawdown of the well of BWSS. Based on this conclusions, the methods to protect the water source site safety are put forward.
