Analyses physico-chimiques des eaux de la Lagune Ebrié effectuées de 1979 à 1981 au cours des programmes "Variabilité interannuelle" et "Baie de Biétri"

Physico-chemical data collections aimed to assess the interannual variability of the lagoon hydroclimate and the impact of an airport dam on the water quality of the Ebrié lagoon.

Synthèse des travaux effectués au CRO sur les végétations envahissantes flottantes (1985-1990). Propositions et recommandations

The present document represents a synthesis of the scientific knowledge gathered by the CRO in the years 1985-1990, and related to the proliferation of aquatic macrophytes, commonly called floating aquatic weeds, in the Ebrié lagoon.

Suivi cartographique de l'expansion des macrophytes envahissant le système lagunaire Ebrié (Côte d'Ivoire)

Remote mapping were realised from December 1986 to September 1989 to describe the seasonal evolution of macrophytes colonizing the surface waters of the eastern sector of the Ebrié lagoon. The vegetal cover of this sector and associated lagoons is essentially composed of Eichhornia crassipes (water hyacinth). Its expansion is favored by the decrease in the salinity of the lagoon waters which is due to rain falls. Its migration through the lagoon environment is ensured by the overflow of the Comoé river. The opening of the Bassam inlet induced its temporary disappearence from the newly created estuarian zone.
