Title: Analysis of the impacts of climate change on hydrological standards in West Africa: Case of Abidjan District (South of Ivory Coast)

Knowledge of quantiles of extreme precipitation as hydrological standards is required for the design of hydraulic projects and many other engineering applications. In the context of climate change in West Africa, the estimation of precipitation associated with extreme events is an issue to be adressed. This raises one main question : « On what basis can new quantiles be developed for the management of hydraulic work construction projects? » The objective of this study is the analysis of the impacts of climate change on the hydrological standards relating to the quantiles of maximum daily rainfall in the Abidjan District (southern Ivory Coast). The methodological approach used to conduct this research consisted in the collection of daily rainfall data covering the period 1961-2014.
