Impact energies vary with the height of water pouring, i.e. the distance between the water delivery point and the soil surface. The effects of the height of water pouring on infiltration in an initially near saturated soil can be tested in the field by two repeated beerkan infiltration runs separated by a short pause (30 min) and using both low (non-perturbing) and high (perturbing) heights of water application. The double two-stage beerkan run methodology was applied in two soils. The infiltration rate at the end of the perturbing stage of the experiment was 0.2-0.3 (sandy-loam soil) and 0.15 (loam soil) times that obtained with the initial, non-perturbing stage whereas, without any perturbing effect, infiltration rates at the end of the second run were 0.5 times those at the end of the first run. Therefore, the methodology distinguished between a decrease in infiltration
