基于Visual ModFlow的苑庄水源地地下水位预测

Predication of Groundwater Level of Yuanzhuang Water Source Based on Visual ModFlow

根据苑庄水源地的水文地质条件,建立了水源地的水文地质概念模型。在此基础上,采用Visual ModFlow对水源地地下水流场进行了数值模拟。误差统计分析表明,数值计算模型在识别与验证过程中的误差较小,模拟效果较为理想。根据所建立的数值模型,并按照设计开采量,对水源地运行后区域地下水位的变化趋势进行了预测。

According to hydrogeological conditions of Yuanzhuang water sources, hydrogeological conceptuall model of water source has been established. On this basis, by using Visual ModFlow, numerical simulation of groundwater flow field in water sources area has been carried out. As showed by error statistical analysis, numerical calculation model has the characteristics of small error in identification and verification process, and has gained an ideal effect. According to the established numerical model, and in accordance with the design of extraction, the trend of regional groundwater level in the water source has been predicated.
