Coastal Modeling System Cms

Verification and Validation of the Coastal Modeling System

There are four reports documenting the Verification and Validation (V&V) of the Coastal Modeling System (CMS): an executive summary, waves, circulation, and sediment transport/morphodynamics, respectively. This is the second technical report (Report 2) that describes the wave modeling component of the V&V study. The goal of the report was to critically assess both general and special predictive skills of CMSWave, a spectral wave model in the CMS developed to address a variety of needs for coastal inlet applications. For model verification, a number of simple and idealized cases were selected to approve the basic physics and computational algorithms implemented in CMS-Wave. For model validation, a collection of more complicated cases with either laboratory or field data representing real world problems were assembled to confirm the overall performance or special capabilities of CMS-Wave. Provided in this report are descriptions of the V&V cases, model set up and boundary conditions specified in each case, and assessment of model performance. Major findings for each case are provided as guidance to users for future applications of CMS-Wave.

Coastal Modeling System (CMS) Users Manuel

The Coastal Modeling System (CMS) is a software package aimed at organizing the Coastal Engineering Research Center's larger numerical models and their supporting software into a user-friendly system that is available to all Corps elements having a need to apply the supported modeling technology. Since some of the models share similar input requirements. output capability. and procedural implementation, efforts are made to standardize these portions of the models as much as possible. FORTRAN 77 programming language is used exclusively in the system software to ensure portability of the models and supporting programs to other computer systems. Graphics programs also make use of DISSPLA software. Models selected for inclusion in CMS are well advanced in their development and have been rigorously tested over a wide range of conditions. The models in CMS can be considered tested, reliable, and mature. The numerical models documented here include: SPH, WIFM, RCPWAVE, CLHYD, SHALWV, STWAVE and HARBD. Numerical model SPH is a parametric model for representing wind and atmospheric pressure fields generated by hurricanes. Numerical model WIFM solves the vertically integrated Navier-Stokes equations in stretched Cartesian coordinates. The model simulates shallow-water, long-wave hydrodynamics such as tidal circulation, storm surges, and tsunami propagation. Numerical model RCPWAVE is a short-wave model used to predict linear, plane wave propagation over an open coast region of arbitrary bathymetry. Numerical model CLHYD simulates shallow-water, long-wave hydrodynamics such as tidal circulation and storm surge propagation.
