Coastal Modeling System (CMS)

The Coastal Modeling System is an integrated 2D numerical modeling system for simulating waves, current, water level, sediment transport, and morphology change at coastal inlets and entrances. Emphasis of the CMS is on navigation channel performance and sediment exchange between the inlet and adjacent beaches. A key objective of this work is to develop, test, and transfer the CMS to Corps Districts and industry for use on specific engineering studies.

CMS-PTM version 2.0.55 – Executable
CMS-Wave Automated Procedure
The ability to systematically execute a large number of CMS-Wave simulations with little user interaction is beneficial in applications where new and/or reruns of numerous simulations are required for model re-validation and sensitivity tests, or for a large number of production runs. 

An automated procedure was developed and is described in a CHETN (in press) and uses a series of MATLAB® scripts to generate CMS-Wave model I/O files, run the model on a PC, post-process model output files to calculate basic statistics for model-data comparison, and plot the model results.  It performs many individual simulations which use different wave breaking formulations, or wave model versions, or input conditions.  The procedure allows users to efficiently setup CMS-Wave model both for successive or simultaneous simulations in Corps projects and to expediently evaluate model results in research studies.

Wave Information Studies (WIS) Data New
CMS Users can use data from the Wave Information Studies (WIS) program to force CMS-Wave with. The main website is located at the link below. Contact WIS@usace.army.mil to obtain 2d Spectra for forcing. Eventually this will be made possible within the Data Portal, but send an email for now.
