Abstract: This paper presents RiverFLO-2D: a two-dimensional finite element model to solve the depth-averaged shallow water and sediment transport equations for river dynamic applications. The model uses a computationally robust explicit scheme that does not require simultaneous solution of matrix systems, and lends well to efficient parallelization. RiverFLO-2D is coded in FORTRAN 95 and parallelized using OpenMP application programming interface. OpenMP provides extensive functionality to develop shared-memory multiprocessing programs and offers immediate access to multi-core processors available in dual and quad core processors without requiring computer clusters. Simulation of the Malpasset dam break with a30963 element mesh demonstrates that RiverFLO-2D compares very well with field data and shows that the parallelized model is able to run more than 4 times faster than the equivalent sequential code in single processor computers.
