基于暗管排水的地下水调控模拟研究
Hydrodynamic Processes of Shallow Groundwater Regulation with Subsurface Drainage
摘要
Abstract
With the help of a three dimensional mathematical model of groundwater of Modflow,the high-efficiency agriculture park in Yuyao City was chosen as study area to research the groundwater dynamic regulation under various rainfall recharges,on the basis of collecting fun-damental information of the park and conducting hydro-geological investigation. According to the hydrodynamic processes of groundwater level under different designed rainfall events and water-level control boundaries in rivers as well as different pipe drainage schemes, the relation-ship between groundwater level regulation and depth and spacing of drainage pipes was analyzed,and then groundwater dynamic drainage sys-tem was determined. The result shows that the optimized drainage scheme is the pipe drainage system with space width 15 m and 2.5 m for depth. The drainage rule for the shallow groundwater at complex hydrogeological region was explored,which will provide scientific decision-making reference for groundwater level control of precision agriculture and prevention and cure of soil salinization.关键词
