Talus refers to a deposit of broken rock fragments that accumulate at the base of cliffs or steep slopes. It is primarily formed due to the action of gravitational forces, causing the rocks to fall and pile up at the slope’s base.
A hillslope is shown below. If the area over the failure plane is 50 m\(^2\) and the weight of the hillslope material (W) is 2000 tons, the Factor of Safety (FOS) for this hillslope in dry conditions is
Cohesion along failure plane = 196 kPa, Dip of failure plane = 60°, Internal friction angle = 30°, Area over failure plane = 50 m\(^2\), Weight of hillslope material = 2000 tons (Round off to two decimal places)
