Steady and intermittent slipping in a model of landslide motion regulated by pore-pressure feedback
David G. Schaeffer, Richard M. Iverson
2008, SIAM Journal on Applied Mathematics (69) 769-786
This paper studies a parsimonious model of landslide motion, which consists of the one-dimensional diffusion equation (for pore pressure) coupled through a boundary condition to a first-order ODE (Newton's second law). Velocity weakening of sliding friction gives rise to nonlinearity in the model. Analysis shows that solutions of the model...
