"Comparison of computational efficiency of explicit and implicit schemes
for the sediment transport problem in coastal zones" Sukhinov A.I., Protsenko E.A., Chistyakov A.E., and Shreter S.A. 
An unsteady spatial twodimensional sediment transport model in coastal zones is considered. The model takes into account the following physical parameters and processes: the soil porosity; the critical shear stress at which the sediment displacement begins; the turbulent exchange; the dynamically variable geometry of the bottom and the level elevation function; the wind flows; and the bottom friction. A spatial threedimensional hydrodynamic model for coastal zones and a transport model for suspended particles are proposed and implemented on a computing cluster. Some numerical results are discussed. Keywords: mathematical model, sediment transport, distributed computing, parallel programming, dynamics of marine sediments, shallow water equations, diffusionconvectionreaction equation.
