浑河流域地表水地下水水质耦合模拟

以浑河流域为研究区，在现场调查、动态监测和资料分析的基础上，根据浑河流域的具体实际条件，包括水文和水文地质条件，分别建立了浑河流域地表水地下水水流耦合模拟模型及水质耦合模拟模型.模拟对象包括地表水、包气带水和饱水带水.运用HydroGeoSphere（HGS）技术系统对地表水和地下水进行联立并行同步求解.根据浑河流域地表水地下水同步动态监测资料，分别对地表水地下水水流和水质耦合模拟模型进行了校正和检验.之后，根据设定的情景方案，应用所建立的模拟模型对浑河流域地表水地下水未来的水质污染状况进行了预报.结果表明：基于HGS技术系统的地表水地下水水流和水质耦合模拟模型能够刻画流域地表水地下水各自的运动规律以及二者之间的水力联系与相互转换关系.若地表水受到污染（如农田施肥），不仅会影响到地表水，也会对地下水造成影响，反之亦然.

Water quality coupling simulation of surface water and groundwater in Hunhe river basin

Based on the field investigation, dynamic monitoring and data analysis, the present study took the Hunhe River Basin as the research area according to the actual conditions of Hunhe River Basin included hydrological and hydrogeological conditions, and established the coupled model of surface water and groundwater current and water quality respectively. The simulation objects included surface water, aeration zone water and saturated zone water. The present study associated surface water with ground water and solved simultaneously by using HydroGeoSphere (HGS) technology system, and respectively corrected and tested the coupled model of surface water and groundwater current and water quality based on synchronization dynamic monitoring data of surface water and ground water. Further, with the setting circumstances, the present study predicted the future water pollution status of surface and ground water in Hunhe River Basin using the coupled model established before. These results showed that the coupled model of surface water and groundwater current and water quality based on HGS technology system can depict the movement rules of surface water and groundwater respectively, as well as the hydraulic relation and law of mutual transformation between them. If the surface water is polluted (e.g., fertilizing farmland), not only impact itself but also affect the groundwater, and vice versa.
