Abstract

A group of methodologies for determining boundary conditions for small coastal models are presented. The lack of oceanographic stations in the Caribbean Sea leads to the use of different sources to determine these forcing, such as: global models for astronomic tides and directional swell (Tide Model Driver, XTide, WaveWatch III, etc.) and remote sensors (Jason). Due to the astronomic tides can present significant differences with measured tide levels, the directional swell models don’t consider shallow water processes and current – wave interaction and the coarse temporal resolution of remote sensors; a new model for the hydrodynamics of the Caribbean was developed. The different methodologies were compared against measurements in the Cartagena region. Through this was determined that the model has a good accuracy, which is equal or better than the other methodologies (swell – WWIII, errors of 16% WWIII and 17% presented model; tides – TMD, errors of 57 % for TMD and 37% for presented model; currents, errors of 17% presented model) and provides more complete information because it includes tides, waves, currents, temperature and salinity with a good temporal and spatial resolution.
