| Abstract: | A local coordinate finite analytic method has been described for thenumerical solution of unsteady groundwater flow in this paper. The stability of thescheme has been proved.The scheme is used to solve two typical problems. The resultsshow that this method has good accuracy.The results are in good agreement withanalytic solutions. The method can be used to calculate complicated geometry. |
