Frequency - Wavenumber Spectrum

Here's an f-ky spectrum for the simulations with the revised offshore wave forcing. It appears that the length scales of the velocity is somewhat bounded by the -0.01 to 0.01 m-1 range as in Reniers 2000 - Figure 7. Interestingly though my color range is an order of magnitude greater, yet my offshore Hrms was lower than his. I'm not sure what to make of that. While I didn't plot the edge wave dispersion curves on the plot I suspect that the energy in the spectrum of the alongshore velocity (the part that 'fans' out to either side at higher frequencies) would lie along one of those curves.
