Wave height decreasing towards shore

HI,

I am having a domain with 55*55 grid. I am running FLOW and WAVE model combined.The model is running without any errors and warnings but when I look into the results, the model is working fine for the TIDE, but in case of wave the significant wave height is decreasing towards the shore , I am attaching the significant wave height image as well as the model files including grid, domain, boundary conditions etc.

I have taken the bathymetry from Gebco, one of my friend is saying it wont give accurate bathymetry nearshore....is the bathymetry influencing the results in this case?

Please have a look at it, and reply fast.



Best regards,


HARISH K.

Hey,

I am currently experiencing a same kind of problem. My waves lose a lot of height as they travel to the shore for no apparent reason, have you in the meantime solved this problem. I have the feeling that something must be wrong in my wave-module. 

 

Thank you in advance.

Have you checked that there is water in this inshore region?  (Check in the FLOW GUI Visualisation tool or get output from the FLOW simulation).  Possibly the GEBCO bathy nearshore means that you have dry cells along the shoreline.......
