A model for the hydrodynamics of Cartagena’s sea region between the towns Galerazamba and Bocachica is presented. The mathematical model (2DH) was constructed using the platform DELFT3D, which considers the effects of tides, waves and atmospheric conditions. The performance of the model was evaluated by comparing its results with measurements of directional waves and currents, for the characteristic seasons of the Caribbean (dry and wet conditions). Static and dynamic measurement probes were used in order to increase the spatial and temporal resolutions of the sea dynamics. After verifying the correct behavior of the hydrodynamic model, it was used to determine both the pattern of currents and waves for each season. Results show a considerable seasonal variability of currents and waves, which on dry season the current flow is directed to the Southwest and strong surge to the Northwest, North and Northeastern, meanwhile for wet season, the currents are directed to the Northeastern and east, and the surge weakens significantly.Downloads
