【摘要】 通过建立地下水系统数值模型,选择地下水模型软件FEFLOW求解,对马池口应急备用水源地启动后,经历两个枯水年,一个平水年后,区域地下水位下降情况进行了预测,水位下降小于3m的面积为174.77km2,下降3～7m的面积为81.86km2,下降7～9m的面积为28.24km2,下降大于9m的面积为15.35km2,预测结果与地下水位监测数据基本吻合。更多还原

【Abstract】 Based on the established numerical model of groundwater system and the groundwater modeling software FEFLOW,the decline condition in regional groundwater level after two dry years and a flat water year later at the starting of Machikou emergency water source are predicted.The results shows that the area of water level drop of less than 3 m is 174.77 km2 and the area of water level drop of 3 ～ 7 m,7 ～ 9 m and more than 9m are 81.86 km2,28.24 km2 and 15.35 km2 respectively.Forecast results are basically consistent with the monitoring data of groundwater level.更多还原
