An OGCM with movable land–sea boundaries

Abstract

An ocean general circulation model (OGCM) with wetting and drying (WAD) capabilities removes the vertical-wall coastal assumption and allows simultaneous modeling of open-ocean currents and water run-up (and run-down) across movable land–sea boundaries. This paper implements and tests such a WAD scheme for the Princeton Ocean Model (POM) in its most general three-dimensional setting with stratification, bathymetry and forcing. The scheme can be easily exported to other OGCM’s.
