What is the effect of reducing water on a slope to mass movements? How can this be done?c What will be an ideal response?
Water is very important in landslides, so increasing surface and subsurface drainage of a hillside will
help stabilize the slope. Drainage serves two purposes: It reduces the weight of the material likely to
slide and increases the shear strength of the slope by lowering pore pressure. Surface waters can be
drained or diverted by ditches, gutters, or culverts. Drainpipes driven into a hillside can remove
subsurface water. Planting vegetation on hillsides helps stabilize slopes by holding soil together and
reducing the amount of water in the soil
