Abstract

Based on the analysis of the plane boundary and vertical boundary of the Karst water system in Mianchi Basin, this paper calculated the groundwater resources of the karst water system by using equilibrium⁃approach. The outcomes show that the annual groundwater level is decreased by 1.79 m during the balance period, it is in the state of positive balance in wet years with water level increasing by 0.01 m, while it is in the state of negative balance in normal and dry years, the groundwater level downrange is 4.60 m in normal years and 16.89 m in dry years. The groundwater level is in a continuous decline according to the analysis data of the groundwater level of boreholes within the region; the groundwater level has been decreased by 40-140 m during the period of 1984-2008, the annual decline of the average groundwater level of boreholes is 5.68 m, the calculation results fit well with the actual data of observation boreholes. The groundwater recharge mainly comes from infiltration of precipitation, making up 74.0%, while the discharge comes from exploitation of water source, covering about 97.5%. [ABSTRACT FROM AUTHOR]
