This study realized at Bondoukou region in north-eastern of Cote d'Ivoire. It aims to analyze hydrodynamic properties of fissured aquifers with a view to improve drinking water supply at this region. Methodology applied for this study started by mapping of fractures networks from treatment of Landsat 7 satellite images with directional filters. After that, it was established relationship among the parameters of groundwater capture and their relation with fracturing and nature of rock formation. Geostatistical analysis of specific capacity of wells from corrected last step drawdown closed the methodology. Use of remote sensing led to map 5000 fractures responsible of water-bearing-layers inside bedrocks. Productive fractures are met between 30 and 60 meters under the ground with these principals directions: NE-SW, NW-SE and E-W. Great yields are also met at weathering between 15 to 45 meters. Approximately 83, 41% of arrival water occurred in the first 30 meters of the basement. Porphyroid granodiorit produced water more than other rocks formations. Variogram structuring of Log (Q/s) revealed that this hydrodynamic parameter can be considered as a regionalized variable with a range equals to 7,36 km. This is a proof of best connectivity of fractures networks identified. Estimation of specific capacities at the whole studied area was made by kriging. All results obtained through this study contribute to best comprehension of hydrodynamic properties of aquifer at North-east of C

The sensitivity of subtropical African river basins to possible future climate change is a matter of some concern. In Ivory Coast, previous works on climate change impacts predict a decrease in annual average water resource by the 2080s between 6.9% and 8.4%. This is a potentially serious issue because of a series of historical resource management decisions that have increased dependence upon water use, such as through major dam building schemes. This paper focuses upon the Buyo Lake catchment, a central resource for the Ivorian people with the aim of providing future water resource scenarios, under climate change so as to develop appropriate adaptation policies. The study applied simulations from the UKMO climate model, HadGEM1 from the ENSEMBLES project 2009, with the A1B emissions scenario in continuous simulation. Daily climate data such as rainfall, temperature, wind speed and relative humidity were input to the SWAT hydrological model. The simulations were performed after model calibration. Analysis focuses on the periods 1950-1979 (baseline), 2035-2064 (2050 horizon) and 2064-2093 (2080 horizon).The results showed that the entire basin of Buyo could experience a serious temperature elevation of +1.34
