Was performed a description and analysis of the process of exchange of water masses in the bay of Cartagena, for which there were effected field exits, in which there took different measurements of oceanographic parameters in the income of the bay (Bocagrande and Bocachica), as well as in the unload of the Channel of the Dique in the bay. Other contributions of water were not born in mind. The measurements were effected in two epochs (dry and humid), in order to determine the influence of the seasonal ends in the dynamics of the bay, principally of the Channel of the Dique, which during the epoch of rains, approximately trebled the contribution in the water volume towards the bay. During the dry epoch and in Bocachica's sector (measurements effected during a cycle of tide) one presented a dominant flow towards the bay, correspondent to a volume of 59.1567x106 m3 during a cycle of tide and an outflow for Bocagrande corresponding to a volume of 76.2013x106 m3, with a decrease of 28.81% in the water volume of the bay; In the epoch of rains and during a cycle of tide, the water volume that entered to the bay (Bocachica and Channel of the Dique) was of 89.8590x106 m3, whereas the volume of exit for Bocagrande was of 78.5392x106 m3, with an increase of 12.59% in the water volume of the bay. These results corroborate the obtained ones for Molars and Mestres (2013), who simulated the dynamics of the bay and determined a variation in the rate of flow of entry and exit to the bay depending of the epoch of the year. There is highlighted the importance of the obtained results, which indicate the variations of the water volume inside the bay, acquiring importance for the socioeconomic and ecological impact that can have in this important system estuarino.Downloads
