MASCARET solves the Shallow Water Equations in 1D (Saint-Venant equations), possibly with non-hydrostatic effects. Finite differences or finite volumes numerical methods are used, depending on the flow regime: stationnary or transient, subcritical or transcritical. A model with interconnected compartments makes it possible to take into account inundation zones, relatively isolated from the major riverbed.

MASCARET can represent:

• Flood propagation and modelling of floodplains
• Submersion wave resulting from dam break
• Regulation of managed rivers
• Flow in torrents
• Canals wetting
• Sediment transport
• Water quality (temperature, passive tracers ...)
