圩区地下水溶质运移预测模拟研究

Simulation of Solute Movement in Groundwater in Closed Levee Areas

以我国南方平原圩区为研究对象 ,分析圩区堤防采用垂直封闭截渗技术后对圩内水环境的影响。采用现场观测、测试、建立封闭圩区地下水溶质运移数学模型 ,以及实例分析相结合的方式进行 ,预测给定时间后某地点的地下水水位及地下水污染情况 ,用以指导类似圩区水利工程建设与管理。

An experiment was carried out in a closed levee area named Gandong dam in Jiangxi province. It is indicated that using vertical close dam anti seepage technique will pose negative effects on water environment in closed levee areas. With field observation data and a groundwater solute movement model, a case study was conducted to forecast groundwater level and contaminant concentration in groundwater at certain time and at given spot.
