How do human activities affect slope stability?

The Impact of Humans on Mass Wasting
Cutting down forests can decrease a slopes stability. Trees add stability by adding root strength to the soil and by putting out excess water. more surface run off and soil erosion.

Subsequently, one may also ask, how human activities affect slopes?

Human Impact on Slopes. Human activities play a crucial role in slope modification. Humans greatly affect slopes negatively, for example, by mining, construction and farming. While humans are the culprits of affecting slopes negatively, they're the ones who can modify slopes to stabilise them, for example, terracing.

Additionally, in what ways does water added to a slope affect its stability? Another aspect of water that affects slope stability is fluid pressure. As soil and rock get buried deeper in the earth, the grains can rearrange themselves to form a more compact structure, but the pore water is constrained to occupy the same space.

Also know, what factors affect slope stability?

The important geotechnical properties affecting stability of a slope are shear strength of material, particle size distribution, density, permeability, moisture content, plasticity and angle of repose. The strength of rockmass is a very important factor that affects the stability of slopes.

How might the process of urbanization increase or decrease the stability of slopes?

For the most part, Urbanization decreases the stability of slopes due to the increased strain on the toe of the slope which decreases the resisting forces. Also, by cutting out flat lots and roads in sensitive areas of the slope we are increasing the driving force on the slope.
