But, human land-use does have a major impact on slope processes. However, it also oversteepens the slope. Removing the basal support can result in slope failure. Click on the figure to the right to see how a roadcut can affect driving and resisting forces. Harvesting timber can also have an impact.
Urbanization also has an effect on slope stability.
Construction of homes on unstable slopes has similar effects. The information is then used to generate a hazard map depicting the various landslide-prone areas. Geological Survey Prevention Controlling drainage and reducing the slope angle reduces landslide potential. Concrete interceptor drains can be constructed to contain runoff and prevent infiltration. Steep slopes can be graded into gentler slopes.
