Gully erosion (Fig. 6) occurs where concentrated surface water scour out the regolith and underlying rock with the debris being either deposited downslope or transported into river systems creating major downstream problems.The gully form and severity is very dependent on the rock type. The very severe to extreme gully erosion is restricted to argillites (crushed), mudstone, and fine ...
