WebThe angle of repose increases (think of a sand castle). In water saturated sediments all the pore spaces are filled with water. Water pressure and water's buoyancy forces reduce the friction between the grains thereby decreasing the angle of repose and possibly causing mass wasting. The two basic classes of mass wasting are flows and slides.
