圩区水环境治理规划及地下水溶质运移预测模拟
Planning for levee region water environment remediation and simulation of solute transport in groundwater
【摘要】 以中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,并建立封闭圩区水环境规划及地下水溶质运移数学模型,通过求解,得出圩区的最优水面率和滞蓄水深、最优外排装机容量和内排装机容量以及大堤的最优封闭率,同时预测了区域内地下水位及地下水污染动态变化情况.
【Abstract】 With the southern plain levee regions of China as examples, the impact of levee closure by vertical closure technology on the water environment of levee regions is analyzed. In combination with practical projects, the optimal watercovering ratio, flood detention and storage depth, installed capacity of the pump stations, and the closure ratio of the levees are derived on the basis of field observation and testing, water environment planning for the levee regions, and development of a numerical model for solute transport in groundwater. Furthermore, the variations of groundwater table and groundwater pollution in the levee regions are predicted.
