Wall shear stress during plug propagates and ruptures in channel. Numerical computation. Solid curves: wall shear stress behind rear meniscus tip before rupture or along whole channel wall after rupture. Dashed curves: wall shear stress in front of rear meniscus tip before rupture. ASME SBC 2011.
Introduction Explain why slopes fail under force of gravity Explain factors influencing slope failure Describe types of mass movements and why they usually occur Discuss importance of mass movement processes in shaping landscapes and associated hazards
