基于Modflow的地下水降落漏斗发展预测及防治对策——以东营市广饶地区为例

以工作区水文地质条件为基础,基于Modflow建立水文地质数学概念模型。通过模型对工作区地下水降落漏斗的发展进行预测,得出5年后地下水流场总体形态基本没有大变化,地下水集中开采水源地水位普遍降低,降落漏斗范围进一步扩大,等水位线降低4~10 m,地下水处于超采状态,并针对此情况提出切实可行的防治对策。

Development Prediction and Prevention Countermeasures of Groundwater Pumping Cones Based on Modflow---Taking Guangrao region of Dongying City as an Example

On the basis of hydrogeological condition in work area, based on Modflow, mathematical concept model of hydrogeology has been set up. By using the model, development of groundwater puming cones in work area has been predicted. It is obtained that the overall shape of groundwater flow field is basically no big change after 5 years, water level of centralized exploitation groundwater source will generally decrease, the scope of pumping cones will expand, equivalent lines will reduce 4~10m, and groundwater will be over exploited. Pointing to these condition, relevant countermeasures have been put forward in this paper.
