CMS-Wave Model: Part 4. An Automated Procedure for CMS-Wave in Resource-Demanding Applications

This Coastal and Hydraulics Engineering Technical Note CHETN describes an automated procedure developed for applying the Coastal Modeling System s wave model CMSWave in resource-demanding projects and research applications. The ability to execute a large number of CMS-Wave simulations systematically with little user interaction is beneficial in applications where new andor reruns of numerous simulations are required for model revalidation and sensitivity tests, or for a large number of production runs. The theoretical background and user s manual for CMS-Wave are available Lin et al. 2008, 2006 Demirbilek et al. 2007. CMS-Wave is part of the Coastal Modeling System developed under the Coastal Inlets Research Program CIRP for simulating combined waves, currents, sediment transport and morphology change at coastal inlets, estuaries, and river mouths Lin et al. 2011, 2010 Li et al. 2011. CMS-Wave is a two-dimensional spectral wave transformation model that employs a forward-marching, finite-difference method to solve the wave action conservation equation Mase 2001. Wave transformation processes represented in CMS-Wave include wave shoaling, refraction, diffraction, reflection, transmission over structures, depth-limited breaking, dissipation, and wave-wave and wave-current-structure interactions. A number of wave breaking formulae included in CMS-Wave have been evaluated in laboratory and field applications Demirbilek et al. 2009 Zheng et al. 2008. CMS-Wave can be used in either on a half- or fullplane mode, with primary waves propagating from the seaward boundary toward shore. Readers are referred to the CMS-Wave technical report Lin et al. 2008 for additional model features and technical details of model capabilities.
