Abstract: The increasing advance in high performance computing allows the evaluation of challenging hydraulic scenarios, like simulation of floods in urban areas that evolve in time over wide spatial domains, for planning prevention and risk management. An advanced numerical model has been designed for applications in real case studies. It is based on adequate description of the spatial domain, on the numerical integration of twodimensional shallow water equations for an accurate evaluation of water depths and velocities and on the use of high performance computing facilities for simulation of flood events on extended real domains. The computational model has been implemented for scalar cache-based and vector symmetric multiprocessing (SMP) architectures, using Open MP directives for the code parallelization. Numerical experiments have been carried out by considering the Toce river test-case. Overall results show that the implementation code for vector SMP outperforms the one based on cache-based architecture in terms of scalability and efficiency.
