Based on the summation of numerical solutions of the free water surface seepage flow, a new concept called Regional Identification Function is put forward. It is pointed out that the reason why the initial flow method is unstable is that the RIF is discontinuous. Linearization continuity method for the RIF is suggested and then a revised initial flow method is presented.

Applying the Euler method to the equation and particularly using the interpolation technique on variable delay, the Euler approximation is obtained. The discrete Euler approximation is extended to the continuous Euler approximation. It is proved that the Euler numerical solutions will converge strongly to the true solution under the local Lipschitz condition.
