Calculated structural mathematical model shows how gravitational moisture drains from root layer of the soil during short-term over moistening. The article presents the results of field experiment. Comparative analysis of the measured and calculated soil moisture reserves shows that the calculation of the water balance in waterlogged soil, taking into account runoff in the soil, calculated in the prescribed dependence, gives an fault which does not exceed the fault of measurement of soil moisture reserves in the field.
