La variabilité climatique et son impact sur les ressources en eau dans le degré carré de Grand-Lahou (Sud-Ouest de la Côte d'Ivoire)
This study aims to show the existence of a climatic variability to the level of the region of Grand-Lahou and to understand its impact on the food of water resource. For that to make, various data and methods have been used (reduced centered indexes, PETTIT test, LEE and HEGHINIAN method).The applic...

| description | This study aims to show the existence of a climatic variability to the level of the region of Grand-Lahou and to understand its impact on the food of water resource. For that to make, various data and methods have been used (reduced centered indexes, PETTIT test, LEE and HEGHINIAN method).The application of the reduced centered indexes to the sets rainfall and runoff times series put in evidence a climatic variability characterized by an alternation of humid, normal and dry phases. The statistical methods show some breaks between 1966 and 1981 that mark a modification of the rainfall and runoff regimes. These breaks are accompanied by a rainfall decrease of 13 to 28 % and a flow decrease of 58 % for the river Bandama. This variability induces some effects on groundwater. Thus, water balance results show the decrease of groundwater recharge. |
