Abstract

Two recently proposed methods are used to relate horizontal infiltration data to soil- moisture diffusivity. The theoretical background is only discussed briefly and more emphasis is given to an experimental verification. With the described methods numerous experiments were performed on two soils under varying initial moisture content in the same soil samples. Data of four representative experiments are summarized in a table and a number of figures. The horizontal infiltration into a silty loam soil with an initial moisture content of 0.08 cm3/cm3 is not in accordance with theoretical expectations, whereas that into a fine sand with the same initial moisture content is in accordance with theory. The latter may be due to the building up of a soil-air pressure in the silty loam which was recorded to be in the order of 40 mbar.
