This paper discusses the effects of water quality on the hydrological and erosion response of non-saline, non-sodic soils during simulated rain experiments. It is well known that rain water quality affects the behaviour of saline soils. In particular, rain simulation experiments cannot be run using tap water if realistic values of infiltration rates and soil erosion are to be found. This paper reports on similar effects for non-saline, non-sodic soils. Two soils - a well-aggregated clay-rich soil developed on marine silty clay deposits and a soil developed on silt loam - were selected and subjected to a series of simulated rainstorms using demineralized water and tap water. The experiments were conducted in two different laboratories in order to obtain results independent of the tap water quality or the rainfall simulator characteristics.
