摘要
给出了一种求解地下水非稳定流方程的局部坐标有限分析法，证明了格式的稳定性。用该格式计算了两个典型问题，表明该方法有较高的计算精度，并能运用几何形状较复杂的渗流问题的计算。
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.
