open TELEMAC-MASCARET The mathematically superior suite of solvers

Hi,
I am trying to calibrate my model against the observed buoy data. Attached is the figure showing the observed data, the simulation without white capping dissipation and with Westhuysen white capping dissipation. I am using Yan's model for wind input. It appears that there is too much dissipation and I'd like to modify some of the parameters.

I have looked up Westhuysen's thesis and understand where the values for "WESTHUYSEN DISSIPATION COEFFICIENT" and "SATURATION THRESHOLD FOR THE DISSIPATION" are used. I have trouble associating Westhuysen White Capping Dissipation (default = 3.29) and Westhuysen Weighting Coefficient (default = 0) with the equations provided in the manual or in his thesis. Can someone provide some explanation on these two parameters?

Thanks.

Edwin

Okay. Going through qmout2.f, I kind of figured out how these two parameters are been applied in the model.

Hello,

very well if you find by yourself. The coefficients of the Westhuysen model correspond to the one of his thesis (in his 2007 paper, there is no combination with the Komen et al. term).
