I am currently using a Pierson Moskowitz spectrum to model the wave energy in the Mediterranean Sea. However I don't think this this is appropriate due to the limited fetch in the coastal area that I'm interested in. Therefore I'm going to switch to a JONSWAP spectrum which will encorporate the fetch too.
I can't find many resources on how to go about calculating fetch except for the fetchR package in R. I am not an R user (more Python/Matlab) although if this is the best option I will happily learn.
Are there any other online resources for calculating fetch in the Med sea?
