What are Topographic factors?

Topographic factors such as elevation, slope angle, slope aspect, general curvature, plan curvature, and profile curvature are considered as the main causes of landslides.

What is Soil Erodibility?

Soil Erodibility (K) is the intrinsic susceptibility of soil to erosion by runoff and raindrop impact. Values of K range from the lowest erodibility, 0.02, to the highest, 0.69. All other factors being equal, the higher the K value, the greater the susceptibility of the soil to rill and sheet erosion by rainfall.
