Variabilité pluviométrique et dynamique hydro-sédimentaire du bassin versant du complexe fluvio-lagunaire Mono-Ahémé-Couffo (Afrique de l'ouest)

2010

This thesis aims to highlight the relationship between climate and water balance process on the basin of the complex river-lagoon Mono-Aheme-Couffo. A better analysis rain/flow is made using rainfall spatialization from interpolation, taking into account altitude and geographical coordinates of hydrometeorological stations. Also, pluvio-hydrological variability and surface states dynamics impacts on sedimentation are examined. Runoff variability and sediment dynamics in the watershed Mono-Aheme-Couffo over the period 1961-2000 in a context of integrated water resources management (IWRM) were analyzed according to the rainfall depths, effects of water releases from the Nangbeto dam operation…
