SMS:CMS-Wave Model Control

CMS-Wave Model Control dialog

The Model Control… command in the CMS-Wave Menu opens the CMS-Wave Model Control dialog. This dialog is divided into sections for different types of parameters which are used by the model as it runs. These include:

Settings

The settings section is used to specify model input options including:

• Forward reflection

• Spatially constant (0.0 – 1.0 range)
• Spatially varied – select a dataset

• Backward reflection

• Spatially constant (0.0 – 1.0 range)
• Spatially varied – select a dataset

• Muddy bed

• None
• Spatially varied – select a dataset (0.0 – 0.1 value range, 0.04 recommended)

• Bed friction
• Matrix solver
• Allow wetting and drying
• Nonlinear wave effect
• Runup
• Infragravity wave effect
• Diffraction intensity
• Currents
• Spatial wind field

• None
• Spatially varied – select a dataset (values in m/s at 10 m)

• Spectral type

• Half plane
• Full plane
• Full plane with *.spc file

• Dates/Times

Wave Source

The wave source options include:

• Spectra – wave state is specified as a wave spectrum on the boundary and the model propagates the spectra over the domain
• Wind – waves are generated from wind energy only
• Spectra and wind – a combination of the spectra and wind types are used
• Simplified formulation – boundaries are specified in the same manner as "Spectra and wind", but the model uses a simplified formulation internally. This can be used for faster run times, however the results will be less accurate.

Output

This section is used to specify option output from the model. The output includes:

• Radiation stresses
• Sea/Swell
• Wave Breaking

Input Datasets

Here the user can specify the format for SMS to write out the input datasets. They can be written in either ASCII or XMDF format.
