Analyze of climate variability and change impacts on hydro-climate parameters: case study of Côte d’Ivoire
نویسندگان
چکیده
The water resources of Côte d’Ivoire are very much used for water drinking supply of populations, breeding and also for the agriculture. But the abundance of this resource knew disturbances as from the years 1968 to 1970. These upheavals resulted in a fall of precipitat ions of 12.4% to 31.4% and flows which varied from 31.40% to 55.4%. The projections carried out on the hydro-climate parameters under scenario A1B w ith the climate model RegCM3 give an increase in the annual average temperatures of 3°C to 4.2°C and a downward trend of annual precipitations from 4.9% from 2100.

Evaluation of Climate Change Impacts on Hydrological Characteristics of Watershed (Case study: Aji- Chai Watershed)
Studying climate change impact on hydrological variables such as runoff has attracted more attention over recent years mainly due to the imposed imbalance in climate system by greenhouse gas emission. Hence, initially in this research, the trend and abrupt changes of hydro – climatic variables were studied using data mining approaches in 18 stations over 40 years (1972-2011) in Aji-Chai waters...
