B-flood 1.0: an open-source Saint-Venant model for flash-flood simulation using adaptive refinement

<p>The French Riviera is very often threatened by flash floods. These hydro-meteorological events, which are fast and violent, have catastrophic consequences on life and property. The development of forecasting tools may help to limit the impacts of these extreme events. Our purpose here is to...
