Water permeability of unsaturated soils in the arid zone

详细

The moisture permeability of sandy soils in the unsaturated moisture content regime has been studied. The intensity of moisture conductivity was measured at certain values of the current moisture. It is shown that the expansion of the range of unsaturated soil moisture makes it possible to determine the point of break in the monotony of the curve of simulation of moisture permeability due to the rupture of the capillary connection. The mathematical model of moisture permeability that takes into account the soil porosity is presented.
