Improving drainage from the slope can reduce the water saturation of the soil or rock mass, which can decrease the incidence of mass wasting. Grading surfaces to increase the slope, cutting out a section at the base of a slope to build houses, and building a road on a slope can all increase the likelihood of mass wasting. Removing vegetation such as trees and grass from the slope can also increase the incidence of mass wasting by removing the root systems that hold the soil together.
