A MESOSCALE WAVE/CURRENT/SEDIMENT-TRANSPORT PARALLEL MODELING SYSTEM APPLIED TO EPISODIC TRANSPORT IN LAKE MICHIGAN
 
As part of the NSF/NOAA Episodic Events Program in Lake Michigan, a wave/current/sediment- transport modeling system has been developed in a massively parallel computing regime for more realistic simulation of the near shore processes. The multi-dynamical processes included are currents, surface wave propagation, bed forms and sediment transport occurring in shallow water bodies. The technical aspects being carried out in this project cover: (1) Parallelization of the circulation model (CH3D), wave generation and propagation model (WAM), sediment transport model (SED) and bottom boundary layer model (BBL); (2) Development of appropriate physics interfaces to account for the dynamical interactions among current circulation, wave propagation and sediment transport in coastal environments; (3) Computer integration of the individual parallel codes based on the developed physics interfaces. This newly developed modeling system has been applied to simulating the transport processes associated with the annual episode of spring sediment resuspension along the southern shores of Lake Michigan. Besides addressing the effectiveness of the parallelization and multiple code integration via the use of MPI, this paper focuses on the understanding of the complicated dynamical interactions of wave/current/sediment- transport. The impacts on the prediction of wave propagation and sediment transport will be demonstrated by showing the differences between the simulations, which do and do not include the multiple dynamical interactions.
