This experiment consists of a shelf accumulating dense water, which spills over an upward slope and a sill, before flowing down a slope into an open ocean region. It's intended as a test of one of the motivating situations for the adaptive coordinate.The nondimensional widths of the 5 regions are controlled by the DENSE_WATER_DOMAIN_PARAMS, and the heights of the sill and shelf as a fraction of the total domain depth are controlled by DENSE_WATER_SILL_HEIGHT and DENSE_WATER_SHELF_HEIGHT.The density in the domain is governed by a linear equation of state, and is set up with a mixed layer of non-dimensional depth DENSE_WATER_MLD below which there is a linear stratification from S_REF, increasing by S_RANGE to the bottom.To force the experiment, there are sponges on the inflow and outflow of the domain. The inflow sponge has a salinity anomaly of DENSE_WATER_EAST_SPONGE_SALT through the entire depth. The outflow sponge simply restores to the initial condition. Both sponges have controllable widths and restoring timescales.
