Fromwe note an increase of the filled surfaces who notice strongly in the bays of Port-Bou t and Koumassi Figure 4 Figure 2 Map of evolution of the stretch of water lagunaire from to In fact, the estuarine bays of Abidjan undergo a strong anthropic pressure which modifies the tldtectino of the masses of water.

Fromwe note an increase of the filled surfaces who notice strongly in the bays of Port-Bou t and Koumassi Figure 4. This reality is made to the detriment of the banks which undergo an unprecedented degrading pressure. In the narrow channels, the currents are exclusively alternative while in the deep coats, the currents are gyrating and waters are badly renewed [ 13 ].
