How does weathering affect slopes
WebWhen the force of gravity acting on a slope exceeds the resisting forces of a slope, the slope will fail and a landslide occurs. External factors can lead to landslides happening, including: heavy rainfall leading to saturation of the ground; erosion of the base of a slope ; changes to the material’s strength through weathering WebDec 1, 2024 · It occurs when the shear stress on the slope exceeds the shear strength of the slope. Changes in rainfall patterns could alter the flux boundary conditions such as infiltration and evapotranspiration, affecting the water pressure in soil. As rainfall infiltrates through the soil pores, the water content of soil will increase and the groundwater ...
