| Abstract: |
| Based on Philip formula, three-dimensional dynamic process of Philip-Dunne and sing-ring infiltration were studied, and also the relationship between of parameter A in Philip formula and saturated hydrau
lic ks as well as computing ks model were explored. The results show is applicable in the analysis of three-dimensional infiltration, and there is a positive power function, affected by experimental methods and it's equipment specifications, relationship between ks and A; The accuracy of Philip formula used in Philip-Dunne infiltration was higher than in singe-ring infiltration; Compared with actual measured ks in infiltration experiments, the forecast ks based on computing model has a overall error below 5%, and then the simply model can be used to estimate infiltration parameters. |
