Modelling of the groundwater-surface water system of the Maozui area of Jianghan Plain, central China

The objective of this study is to get a better understanding of the local groundwater-surface water system at a typical site of the Jianghan plain of central China, in the vicinity of Maozui, and eventually to give a perspective in order to understand the regional hydrogeological system of Jianghan Plain. Conceptual and analytical models were established before using FEFLOW software liar modelling. Models were elaborated and improved with information notably about the aquifer's physical configuration and the elevation of piezometric levels. The results show that piezometric level forms a dome in the middle of the meander and groundwater flows radially from there to the river with a flux of 4.62 x 10(3) m(3)/d across the boundaries.
