How can I get the files to run BISCA case?

Hi! I’m trying to run a real case similar to the Rip Current Test Case, but I have some problems with the boundary conditions, so I want to look how BISCA case uses the files to obtain good results. Someone knows how can I get these files? Or they aren’t public?

I also want to get these files since it is really useful for people to set up a realistic rip current case.
