Title: Numerical simulation of groundwater system in the south of Qinwangchuan basin based on GIS technique and FEFLOW
Abstract: Based on the analysis of the geological and hydrogeological conditions,the scope of the research area and the boundary conditions were determined and the conceptual model,mathematical model and numerical model of the groundwater system in the research area were constructed with the help of GIS technology and FEFLOW software.Meanwhile,the numerical model was calibrated with the observed dynamic level of groundwater from 2004 to 2005,and the groundwater system at present(in 2004) simulated and analyzed by using the calibrated model.The results confirmed that the established model could well reflect the distribution and combination of the hydrogeological conditions and could be used to create a numerical simulation.We selected 2005 as the beginning year and 2015 as the ending year,and used the model to forecast the future conditions in the research area.After the model has run for ten years,the groundwater level would rise 3~5 m in the north section,5~10 m in the central section and 10~15 m in the south section.Through an analyis of the rising range of groundwater level of the research area,the technology basis was established to actualize the measure of drainage for future and provide a basis for selecting the location for measuring the drainage.
