| Abstract: | Based on the basic equation fo diffusion wave, a speical equation only containing water level has been deduced. Then two numerical models for diffusion wave have been gained by controlled volume way as well as finite element way, and no difference for the two models under some conditions has been proved. Newton iteration method is given for nonlinear equation groups. |
