A Numerical Infiltration Model in Civil Engineering and its Comparison with Geo-Seep Software

Article Preview

Abstract:

A numerical couple model of infiltration and runoff is presented which could simulate infiltration more accurately in theory. While a usually tool to solve infiltration problem is Geo-Seep software which contained in Geo-Slope package. In this paper, the difference of infiltration capacity between two above methods are researched. A numerical orthogonal test considering saturated conductivity (Ks), rainfall intensity (R), slope gradient (S) and Manning roughness of slope surface (n) is adopted to explore the difference. Calculation results show that the maximum difference reaches 38.25% and the biggest influence factor is Ks.
