The Dam Breach Model uses:

•The Finite Volume Method to solve the Shallow Water Equations

•The HLL Riemann Solver to solve normal fluxes at control volume faces

•Linear reconstruction of gradients to improve model stability in distorted Elements

•A multi-dimensional limiter to suppress non-physical oscillations near discontinuities

•An implicit scheme utilising a Taylor series expansion to solve the Friction terms

•Time Integration Schemes during run iterations

•A Courant-Friedrichs Lewy (CFL) condition to maintain time step stability

The Dam Breach Model supports both Newtonian and Non-Newtonian Friction Models.
