- •
Critical shear stress increased with soil moisture below the plastic limit.
- •
Above the plastic limit critical shear stress decreased and was fairly constant.
- •
Critical shear stress was lower for a tilled field compared to a grassed waterway.
- •
Potential changes in soil detachment capacity with soil moisture were demonstrated.
- •
Incorporating dynamics of critical shear stress could improve erosion predictions.
