NEMO v4.2.x now includes the SWE 2D shallow water module. Documentation is lacking, however.

Is there an example configuration somewhere that could be compiled and executed? A simple idealized test with closed boundaries would be fine.

There is the tests/SWG example that is:

" Square basin blown with an analytical wind. Vertical structure allows only one mode associated with reduced gravity to develop. This configuration is based on [[T17](https://sites.nemo-ocean.io/user-guide/tests.html#id23)]. Also runs with RK3 time stepping."

…would appear to be exactly what you are asking for. In case you miss it, the reference is:

A. Adcroft and D. Marshall. How slippery are piecewise-constant coastlines in numerical ocean models? _Tellus A: Dynamic Meteorology and Oceanography_, 50(1):95–108, 1998. [doi:10.3402/tellusa.v50i1.14514](https://doi.org/10.3402/tellusa.v50i1.14514).

Thanks Andrew, this is what I was looking for.
