Model part of larger framework
Note on status model
Date note status model

Spatial dimensions	3D
Spatial extent	Landscape-Scale, Watershed-Scale
Model domain	Coastal
One-line model description	Steady-State Spectral Wave Model
Extended model description	STWAVE (STeady State spectral WAVE) is an easy-to-apply, flexible, robust, half-plane model for nearshore wind-wave growth and propagation. STWAVE simulates depth-induced wave refraction and shoaling, current-induced refraction and shoaling, depth- and steepness-induced wave breaking, diffraction, parametric wave growth because of wind input, and wave-wave interaction and white capping that redistribute and dissipate energy in a growing wave field.

Pre-processing software needed?	Yes
Describe pre-processing software	To assist STWAVE users in generating input files and visualizing output files, a user interface has been built for STWAVE within the Surface-water Modeling System (Brigham Young University Engineering Computer Graphics Laboratory (ECGL) 1997). The SMS interface supports grid generation, interpolation of current fields, generation of input spectra, visualization of wave heights, periods, and directions, and visualization of output spectra. Non-Corps users can get information from ECGL (http://www.ecgl.byu.edu).
Post-processing software needed?	No
Describe post-processing software
Visualization software needed?	Yes
If above answer is yes
Other visualization software	The SMS interface supports grid generation, interpolation of current fields, generation of input spectra, visualization of wave heights, periods, and directions, and visualization of output spectra. U.S. Army Corps of Engineers users are supported through the Coastal and Hydraulics Laboratory, and non-Corps users can get information from ECGL (http://www.ecgl.byu.edu).

Describe processes represented by the model	STWAVE simulates depth-induced wave refraction and shoaling, current- induced refraction and shoaling, depth- and steepness-induced wave breaking, diffraction, wind-wave growth, and wave-wave interaction and whitecapping that redistribute and dissipate energy in a growing wave field.
