■Update landslide model
·Change surface gradient method (SGM) in TVD scheme to upwind method for source terms to avoiding negative depth at cell face and ensure well-balance property;
·Changed the flux boundary condition at wet-dry boundary to avoid numerical oscillation;
·Change cell-center based method of non-hydrostatic model to cell-corner based method to avoid numerical osscillation of non-hydrostatic pressure;
·Add a dispersion correction term into governing equations to improve vertical effect of motion.
·Add immersed boundary method (IBM) for slide-structureinteractions.
