Abstract


According to local nomenclature, there are four sub lagoons that represent the lagoon system of Grand-Lahou. The Tagba lagoon is the most important one because it is in contact with the sea through the mouth of Bandama river. The Morphology and the bathymetry constitute a challenge for local residents whose main activity is fishing. The present study aimed to update the bathymetry of the lagoon. The depths obtained are low, 3 m on average with maximum of 6 meters. The action of river currents and tidal current is responsible of the morphology of channels.

Abstract: (french)


Selon la nomenclature locale, il y a quatre sous lagunes qui constituent le système lagunaire de Grand-Lahou. La lagune Tagba est la plus importante d’entre car elle est en contact avec la mer par l’embouchure du fleuve Bandama. Sa morphologie et sa bathymétrie constituent un enjeu pour les riverains dont la principale activité est la pêche. La présente étude avait pour objectif la mise à jour de la carte bathymétrique de la lagune. Les profondeurs obtenues sont faibles, 3 m en moyenne avec un maximum de 6 mètres. Les courants fluviaux et de marée sont responsables de la morphologie des chenaux.
