Abstract
This study
investigates the impact of rainfall-induced soil consolidation
and soil surface sealing processes over time after tillage on
soil erosion during concentrated flow. The soil erodibility
(Kc) and critical flow shear stress (τcr) were examined for
identical, artificially created soil samples under simulated
rainfall. As these rainfall-induced soil structural changes are
inseparably ...

This study
investigates the impact of rainfall-induced soil consolidation
and soil surface sealing processes over time after tillage on
soil erosion during concentrated flow. The soil erodibility
(Kc) and critical flow shear stress (τcr) were examined for
identical, artificially created soil samples under simulated
rainfall. As these rainfall-induced soil structural changes are
inseparably related to soil moisture variations, the effects
are evaluated for different soil moisture conditions. [--]
