Question

Define gully erosion how can we reduce soil degradation

Answer 1

Gully erosion is the removal of soil along drainage lines by surface water runoff. Once started, gullies will continue to move by headward erosion or by slumping of the side walls unless steps are taken to stabilise the disturbance

Answer 2

Gully erosion occurs when running water erodes soil to form channels deeper than 30cm. Gullies start when fast flowing runoff hits a 'nick' point such as a rabbit burrow, root hole, stock/vehicle track, or bare soil.Method 1 Using Basic Erosion Prevention Techniques
