南通市第四纪松散沉积层地下水资源评价规划三维数值模型

Three-dimensional numerical model for groundwater resource evaluation and plan in loose Quaternary sediments in Nantong

根据南通市第四纪松散沉积层地下水系统的水文地质机制,构建了地下水运动的三维数值模型,并在模型识别、验证的基础上,针对各含水层地下水位的控制要求,调整了现有地下水的开采布局,以乡镇为单位,确定出各含水层的地下水可开采资源量及最优开采布局,并预测了2006年底至2021年底逐年地下水水位动态变化情况。

A three-dimensional numerical model was established according to the hydrogeologieal mechanisms of the groundwater system in the loose Quaternary sediments in Nantong. Based on the validation and verification of this model, the current exploitation pattern was adjusted for better control of the water table of each aquifer. Then, the exploitable quantity of groundwater and the optimal exploitation pattern were determined for every village or town. A prediction of the dynamic change of the groundwater table from 2006 to 2021 was also made.
