Dam break flows or floods have become a very important topic for engineers. As a part of a risk and safety analysis it is now current to produce inundation maps consistent with different dam failure scenarios and conditions. These maps are based on numerical simulations and on computational models of dam-break floods. The dam-break problem is now as a real problem in engineering practice that must be solved by computational models according to real experience and knowledge, based on historical events, physical models and sensitivity analysis. MPflow uses state-of-the-art numerical methods for interface capturing of the water-air interface providing highly accurate modeling.
