青岛市黄岛区潮河水源地地下水数值模拟

Numerical Simulation of Groundwater Sources of Chaohe River in Huangdao District in Qingdao City

摘要:

在分析研究青岛市黄岛区潮河流域水文地质条件基础上，建立了水文地质概念模型和地下水流数值模拟模型，利用地下水水位动态监测资料对模型进行了识别，并预测了三枯一丰一平条件下地下水最大开采量以及水位、降深分布情况。结果表明，模型验证拟合结果较好，地下水最大开采量为2.4万m3/d，地下水开采不会引起地面沉降、海水入侵等问题。

Abstract:

On the basis of studying hydrogeological condition of Chaohe river basin in Huangdao district in Qingdao city, hydrogeological conceptual model and numerical simulation model of groundwater flow have been established. The maximum of groundwater exploitation and the groundwater level as well as the drawdown have been predicted in three dry years, one wet year and one flat year after the model identification by using dynamic monitoring data of groundwater level. It is known that the calculated results can fit the measured data well. The maximum of exploitation of groundwater is 24000 m3/d, and will not lead to land subsidence and seawater intrusion.
