基于Visual Modflow模型的黄河滩地地下淡水资源评价

通过在东营市利津县黄河滩地使用国际通用化软件Visual Modflow的SEAWAT模块，建立了三维变密度非稳定水流和溶质运移耦合模型，用数值模拟方法对研究区进行了地下水资源评价和开采井的优化布置，并对设计开采方案下未来10年的地下水位和咸水运移范围进行了预报。结果显示：利津黄河滩区大致以黄河大堤为咸淡水分界面；按水源地设计方案进行开采，采补趋于平衡，具有补给保证；未来10年，在设计开采量下，咸水不会影响开采井水质。Visual Modflow在利津黄河滩地地下水资源评价中的成功运用，为研究区地下淡水资源的合理开发利用提供了科学依据，具有很好的应用和推广前景。

Groundwater Resources Assessment and Reasonable Exploitation in Lijin Yellow River Beach

The SEAWAT module of the international universal software Visual Modflow was used in Lijin County in Dongying to build a three-dimensional unsteady variable density model which is a coupling model of groundwater flow and solute transport. Also, it used numerical simulation method to evaluate groundwater resources, optimize pumping well configuration and make a forecast of the groundwater level and transport plume of salt water in the next 10 years. The results showed that: Firstly, the interface between salt and fresh water is approximate the Yellow River levee in Lijin Yellow River Beach. Secondly, according to the designing scheme, exploitation and replenishment kept balance, so that the supply of groundwater was guaranteed; Thirdly, in the next 10 years, the salt water will not transport to the pumping well. The successful application of Visual Modflow in Yellow River Beach in Lijin County provides a basis for the rational development and utilization of groundwater in this area and has a good future application prospect.
