What is the effect of removing material from the downslope end of a landslide? What will be an ideal response?
First, resisting forces are reduced in general. This is particularly true where slumps are involved. The
portion of a slump where the landslide angles upward toward the surface actually contributes forces
that counter the tendency of the rest of the mass to move down slope. Unloading this sensitive area
decreases resistance to movement. Second, excavating the downslope end of a landslide changes the
slope angle locally, thus removing lateral support and encouraging slumping or block glides, the later
typically occurring where bedding planes are exposed.
