|Describe processes represented by the model=Bottom orbital velocity is calculated from surface wave conditions using linear wave theory. A spectral approach is used. If input wave data are just wave height and period, a spectrum is estimated based on those as described in Wiberg and Sherwood 2008. Several spectral representations are available, and spectra can be estimated based on wind speed if surface wave conditions are unknown. | |||
|Describe key physical parameters and equations=See Wiberg and Sherwood 2008, Computers & Geosciences 34: 1243-1262 for key equations. | |||
|Describe length scale and resolution constraints=This is a point model and not dependent on length scale or resolution. | |||
|Describe time scale and resolution constraints=This is a point model and not dependent on time scale or resolution. | |||
|Describe any numerical limitations and issues=The calculations assume the waves are wind waves with periods in the range of 0-~30 s. If the waves are much larger or produced by a different mechanism, the calculations are not likely to be accurate. | |||
