GOTM is the result of the effort by a number of people to make 'state-of-the-art' turbulence model for natural waters. Since its inception more than 20 years ago GOTM has grown into a full-fledged 1D water column model with a very extended configuration possibilities including coupling to a collection of bio-geochemical models.
Developed by a group of volunteers over 20+ years.
GOTM configured in Lake mode - i.e. using a hypsograph to specify depth-area relations. The GOTM lake branch is kept in sync with the master branch and merging is hopefully soon to occur.
