This repo is forked from ufs-weather-model, and contains the model code and external links needed to build the UFS coastal model executable and model components, including the ROMS, FVCOM, ADCIRC and SCHISM plus WaveWatch III model components.
somewhat related: the restart capabilities need to be tested explicitly at some point (#113)
