[0029] The preferred embodiments of the present invention are further described below:
[0030] The technical roadmap of the present invention is as follows figure 1 As shown, a method for measuring the soil infiltration wet front and its relationship with the surface micro-topography includes the following steps:
[0031] The first step is to prepare the soil profile. Fill the soil in layers in the soil tank, filling 5cm each time, and use a wooden board to flatten and smash the soil surface to reach the actual bulk density of the soil in the study area;
[0032] The second step is to set the initial infiltration front. After filling, the soil tank is placed on the test slope, and the contour line of the soil surface near the plexiglass is drawn on the plexiglass with a pencil as the initial infiltration front, which is counted as F0 ;
[0033] The third step is the artificial rainfall simulation test. After the rainfall starts, the wet front is marked on the plexiglass at regular i...
