Résumé
To face the difficulties involved in supplying freshwater to Abidjan (Côte d’Ivoire), the Aghien Lagoon is a potential resource for production of drinking water. A hydro-meteorological network was installed with the objective of assessing the sustainability of the lagoon in terms of both quantity and quality. Each water level station is equipped with a piezometric probe associated to a HYDREKA standalone data recorder with a communication capability (Octopus LX). A manually read staff gauge is used to control the water level determined by the pressure probe. Data are collected monthly.
