| Abstract: | This article deals with phreatic aquifier with free water surface in humid regions. Based on principle of continuity and Darcy's law, explicit FEM is applied to analyses groundwater in humid regions. Spatial variables in calculated ranges are partitioned by finite elements and time variables are calculated by successive integration. Verification of calculated cases indicates the proposed method is of higher accuracy. |
