ELCOM

ELCOM is a three-dimensional hydrodynamics model used for predicting the velocity, temperature and salinity distribution in natural water bodies subjected to external environmental forcing such as wind stress, surface heating or cooling.

ELCOM is designed to facilitate modelling studies of aquatic systems over time scales extending to a few weeks, though the limit of computational feasibility depends on the size and resolution requirements of an application and computational resources. ELCOM is suited for comparative studies of the summer and winter circulation patterns, spring versus neap tidal cycles, or dispersal conditions under different flow regimes.

ELCOM can be run either in isolation for hydrodynamic studies, or coupled with CAEDYM for simulation of biological and chemical processes.
