New features have been added and several necessary changes have been made to the standard WAM-cycle4 (WAMC4) model code for it to run efficiently when applied to shallow water regions. The restriction of having a source term integration time step smaller than or equal to the propagation time step was relaxed, considerably reducing the computational time needed. An additional reduction in computing time and an increase in accuracy were obtained by introducing a split-frequency time step. There is now a choice of using the octant or quadrant coordinate system for the propagation of the wave energy. The source term integration and, more particularly, the use of a limiter on the energy growth, were studied. For the evaluation of the energy decay in shallow... |

The primary objective of the EC-MAST III project PROMISE (Pre-Operational Modelling In the Seas of Europe) is to develop a framework to optimize the application of existing pre-operational dynamical models of the North Sea in order to quantify the rates and scales of the exchange of sediments between the coast and the near-shore zone. This framework should also be applicable to other coastal areas and for broader management applications. One of the components of this framework is the development and the dissemination of a spectra! wave model capable of dealing with shallow water conditions and with the interaction between tide and waves. At the beginning of the project, it was opted to improve the capabilities of the WAM-Cycle 4 model, a model which is... |
