基于GPR的SWAT-MODFLOW模型的耦合计算及应用研究——以西安黑河流域为例

Application of GPR Based SWAT-MODFLOW Model’s Coupling Calculation in Xi’an Heihe River Basin

摘要: 西安黑河流域水文变化情况将直接影响到西安市约3761万居民的生活用水问题，而西安黑河流域地表水–地下水之间的水量与水质交互作用极大的影响了西安供水的安全。本文基于GPR技术和SWAT-MODFLOW模型，模拟地表水–地下水交互作用探索地表地下水文循环的响应机制，评估研究区水资源的潜在变化，进而探讨适应性调控对策。

Abstract: Xi'an Heihe River basin hydrological changes will directly affect the water supply of about 3761 million residents in Xi’an, and quantity and quality of the Xi’an Heihe River Basin and its interaction between surface water-groundwater would surely have a great impact on the safety of the water supply in Xi’an. Based on the GRP technology and the coupled SWAT-MDFLOW, this paper simulates the surface water and ground water’s interaction to explore the hydrological respondent mechanism, evaluates the potential changes in water resources assessment study area, and then discusses the adaptive counter measure.
