Application of Comprehensive Water Flow Numerical Solution at Yifeng River Basin

Abstract:

Our article is studied with the improvement of a physically-based numerical model that uses for a new finite element solution to the transient or steady problems of the groundwater and surface water flows of a specific region with the help of a Geographic Information Systems (GIS) to store, manage, represent and take decides on all condition. Our article research subsurface and surface model proposes groundwater and surface water interact to be depth averaged through a new interpretation of a linear river flood calculus method. Overland flows and infiltration rates production processes are estimated by a sub model which records for this kind of groundwater and surface water interactions. Groundwater and surface water interactions discuss also new evapotranspiration and evaporation processes as a spread discharge from ground water table, non-saturated subsoil and surface water. The practical application regards the present flooding of six gauge stations, in the context of the water resources fate and use at the Yifeng River basin (similar to 776.6m²), Jiangxi China. Our article developed model DMSYQ was applied to the complex geology and the whole of the water resources of the Yifeng River basin.
