Rainfall infiltration into bare soils

摘要: Raindrop impact destroys the surface aggregates of soils and gradually forms a continuous crust. Infiltration rates bare are determined by this process. A theoretical model presented previously was tested under field conditions with sandy loam soil. The effect crust's structure three rainfall intensities in wetting drying cycles. results tests confirmed model. According to potential infiltration rates, soils, can be predicted equation It = (Ii - If) ·e−γptl + If. study demonstrated quantitatively that major factor determining reduction is crust formation not moisture regime.
