Panina S.S, Shein E.V. MOVEMENT OF WATER IN AND LOW HEAD GRAVITY FILTRATIONSoil moisture movement depends on the upper boundary conditions (the presence or absence of hydraulic pressure). It was showed in field experiments on grey cultivated soil that the presence of pressure head causes the preferential water movement. The best reproducibility of the field moisture dynamics by physically based water migration mathematical model was observed when use the data on granulometric composition.Key words: soil, hydrophysics, mathematical model, experimental evidence, physical properties of soils, pedotransfer functions.
