The tidal wave when entering to the estuaries can be modified by morphological and meteorological aspects. Understanding the sea level generated by the tide contributes to the identification of possible flood zones in the event of progressive increases in this sea level associated with climate change and / or sudden changes due to meteorological effects. The Gulf of Uraba is an estuary characterized by having a complex hydrodynamic system affected by oceanographic and atmospheric agents and the presence of the mouth of the Atrato River. Among the oceanographic is the tidal wave. In order to characterize the tide inside the Gulf of Uraba, tide-gauge records located in the district of Turbo (Coast Guard Station) and the municipality of Acandi (Bahía de Sapzurro) were analyzed. Spectral analysis was used to determine the astronomical tide, with which the amplitudes, periods and phases associated with the tidal constituents were obtained. The tidal constituents with the highest amplitudes for both tide gauges were K1 and M2. The behavior of the tide was identified as mixed, mainly semi-diurnal. For the characterization of the meteorological tide, the probability distribution function was used and using data from the reanalysis of atmospheric pressure and wind fields from the ERA5 platform, the correlation of these two variables against variations in the sea level was evaluated. The results suggest that an important percentage of the sea level variations are associated with local effects such as gulf morphology (bathymetry, gulf shape).
