ABSTRACT
ABSTRACT: This paper presents a parallel solver for the simulation of transient shallow water flows in the presence of wetting/drying fronts. A first order explicit finite volume numerical scheme on unstructured triangular grids has been adopted to solve the two-dimensional shallow water equations. The parallel implementation relies on a dynamic domain decomposition technique intended to ensure the balance of the computational load during the simulation. The strategy developed allows the parallel computation of surface geophysical flows, such as floods or dambreak events in real scenarios, where the wet domain is dynamically changing and a static domain decomposition technique is inefficient. The inter-processor data communication is incorporated by the message passing interface (MPI) protocol. A practical application is presented to validate the performance of the implementation.
