This paper describes the software ORSADEM, which solves the one-dimensional (1-D) shallow water equations written in conservative form by numerical schemes suitable for the modelling of shocks and discontinuities generated by a dam break. Unlike the majority of the commercial software, ORSADEM automatically defines the model cross-sections based on the terrain digital elevation model (DEM) and automatically maps the flood prone areas solving the hydraulic equations. The flooded area is mapped using a new method congruent with the unidimensionality of the model. ORSADEM does not need any external platforms. The software has been developed by researchers of the Department of Civil and Architectural Engineering at University of Pavia and it is here presented applied to the case study of the Brembo River.

Abstract
This paper describes the software ORSADEM, which solves the one-dimensional (1-D) shallow water equations written in conservative form by numerical schemes suitable for the modelling of shocks and discontinuities generated by a dam break. Unlike the majority of the commercial software, ORSADEM automatically defines the model cross-sections based on the terrain digital elevation model (DEM) and automatically maps the flood prone areas solving the hydraulic equations. The flooded area is mapped using a new method congruent with the unidimensionality of the model. ORSADEM does not need any external platforms. The software has been developed by researchers of the Department of Civil and Architectural Engineering at University of Pavia and it is here presented applied to the case study of the Brembo River.I documenti in IRIS sono protetti da copyright e tutti i diritti sono riservati, salvo diversa indicazione.
