Detailed explanation-1: -The amount of hill slope erosion largely depends on how the land is used. Sheet erosion occurs when a thin layer of topsoil is removed over a whole hillside paddock-and may not be readily noticed. Rill erosion occurs when runoff water forms small channels as it concentrates down a slope.
Detailed explanation-2: -Sheet, rill and gully erosion is the unwanted removal of soil from the land surface or through incised channels by the action of rainfall and runoff. Protecting the soil from runoff stops potential land degradation and assists with water quality protection.
Detailed explanation-3: -Gully erosion is a widespread and often dramatic form of soil erosion caused by flowing surface water. It consists of open, unstable channels that have been cut more than 30 centimetres deep into the ground. Gully erosion is a result of the interaction of land use, climate and slope.
