Abstract: For the computation of saturated-unsaturated water table flow, a kind of difference scheme of irregular convex polygon mesh is developed. Using this method, saturated-unsaturated seepage flow is calculated to AKAI's sand model and KOM-ADA's reservoir model. The results obtained here are compared with results ob -tained from computations in which rectangled difference meshes were used. The applicableness and accuracy of this method are also discussed.
