Experimental Research on Characteristics and Affecting Factors of Finger Flow during Redistribution in Sandy Soil
水分再分布过程中指流特性及影响因素的实验研究

The process of water transferring through soil zone can be divided into two phases:the foregoing infiltration and the following redistribution. Finger flow as a form of the preferential flow of water,differs from macro-pore flow and funnel flow. It has been validated that finger flow can occur during the redistribution following the infiltration of soil water. However,domestic studies on finger flow are very few at present,and cognition about it is very scarce either. Hereby,in this paper,the experiments we...
