  1. CMS FLOW/WAVE Inline Steering

    It is hard to be sure what is going on without looking at the model setup, solution, and data, but from what you describe it seems like the simulated waves are not breaking early enough to generate currents at your (deeper) calibration station. Unfortunately, CMS-Wave does not give the user the option to calibrate the wave breaking and default parameters are used. However, given the 2-m wave height and 7-m water depth, I wouldn't expect much wave breaking. It could be that the current you are observing is actually generated in shallower water but is not being captured by the model. You can try increasing the cross-shore resolution to see if that improves the results.

    CMS outputs the actual sediment transport rate in both the x and y directions. If you would like to obtain an estimate of the potential sediment transport, you can calculate this with the the sediment concentration capacity, water depth and current velocity and using the Data Calculator in SMS as Qxstar = U*h*Ctstar, and Qystar = V*h*Ctstar where Qxstar and Qystar are the potentiual sediment transport rates in the x and y directions, U and V are the depth-averaged current velocities in x and y, h is the total water depth, and Ctstar is the total load, depth-averaged sediment concentration capacity. Note that in CMS, Ctstar is in kg/m^3 so the resulting transport units from the equations above will be kg/m/s and can be converted to m^2/s by dividing by the sediment density. I hope this helps. I also recommend you visit the CMS wiki at http://cirp.usace.army.mil/wiki/CMS. Alex
