摘要
本文以位于西南典型喀斯特地区的贵州普定后寨河流域为研究对象,采用等效连续导水介质体概化方法建立喀斯特流域地下水数值计算模型。运用MODFLOW中的排水沟渠子程序包以及河流子程序包,构建考虑地表河与地下河系统与含水层地下水流交换水动力过程模拟方法,分析后寨河流域地下水流运动特征,估算含水层补排水量。模型计算的地下水位动态变化与实测过程相比较,取得到了较好的模拟结果。为我国南方喀斯特流域地下水模拟计算及其水资源估算提供参考依据。
A typical karst watershed in the Southwest karst region of China,the Houzhai river basin in Puding county of Guizhou province,was selected for developing a numerical groundwater model on the basis of the conceptualized equivalent continuous medium.The simulation of groundwater interactions with river and groundwater system were executed by using the sub-programs drain and river packages of MODFLOW.The characteristics of the groundwater movement are analyzed and the water discharge in the groundwater aquifer is estimated.The simulated results are reasonable by comparing the simulated groundwater tables with the observed processes.This study offers the scientific base for groundwater simulation and water resources evaluation in the karst areas of Southwest China.
