| Abstract: |
| During muddy irrigation and runoff caused by rainstorm, t he soil framework is changed by the layer of mud sediment which is closely compact ed. The soil infiltration ability is mainly mastered by closely grained soil. A long with the entrapment of soil air, the effect of entrapment on infiltration i s different when sand content is different. According to the test results of mud dy water infiltration and the analysis of influence mechanism in the course of i nfiltration, this paper revise the model of kosjkv, and indicates that the sand content of muddy water affects infiltration parameter and infiltration index rem arkably. |
