Trois méthodes géophysiques (résistivité électrique, bipôle électromagnétique MaxMin et V.L.F./EM16) ont été conjointement utilisées pour évaluer leur efficience dans l'identification et la localisation précise du contact entre les granitoïdes et les schistes volcano-sédimentaires du bassin versant de Bidi d'une part et d'autre part, entre schistes et amphibolites à Kièbelga, dans la province du Yatenga. Dans les cas étudiés, le bipôle électromagnétique MaxMin en bobines horizontales (fréquence de 3250 hertz avec une séparation des bobines de 100 m) s'est révélé être le plus efficace. In the Lower Proterozoic (Birimian) crystalline basement of Burkina Faso, underground water resources are found associated with zones of weakness (faults, sills, geol...

However, the decrease in rainfall in the region since the late 1960s and the demographic pressure on the land are significantly affecting groundwater recharge. In order to exploit this groundwater sustainably, it is necessary to identify potential recharge areas for a better capitalisation of this resource. The objective of this study is to map the recharge potential of the existing aquifers making use of remote sensing and GIS techniques and to make a validation based on chloride and tritium contents in the borehole water. The processing carried out on the Landsat 5 and Landsat 8 images combined with a digital elevation model (ALOS PALSAR), highlight the lithological, linear and topographical characteristics of the study area. In addition, various supervised classification algorithms were used to produce the most accurate land use map. Field campaigns ...

Research paper thumbnail of Climate Variability And Groundwater Storage In A Weathered Crystalline Rock Aquifer: Evidence From Long-Term Monitoring In The Soudanian Area Of Burkina Faso

International audienceWeathered crystalline rock aquifer systems which underlie much of the tropi... more International audienceWeathered crystalline rock aquifer systems which underlie much of the tropics including 40% of Sub-SaharanAfrica, represent a distributed and potentially climate-resilient source of freshwater. The impacts of climatevariability, land-use change, and abstraction on these low-storage aquifer systems are not well understood,particularly in semi-arid environments. We review evidence from a multi-decadal chronicle of groundwater levelsin Ouagadougou, Burkina Faso. The chronicle reveals both seasonal responses of low amplitude (~1 m) tomonsoonal rainfall and a longer-term oscillation of greater amplitude (several metres) that can be linked to decadalvariations in precipitation characterized by the Sahelian Drought. The multi-decadal chronicle at Ouagadougoudemonstrates a strong relationship between groundwater storage and climate variability. Current research seeksto: (1) estimate the volume of groundwater storage changes by applying storage co-efficients derived fro...

Research paper thumbnail of Analysis and numerical modelling of large-scale controls on aquifer structure and hydrogeological properties in the African basement (Benin, West Africa)

Spatial analysis of borehole and hydrogeophysical data suggests that large-scale weathering profiles, aquifer transmissivity and storage properties are better correlated to a palaeo-weathering surface. Multi-model analysis, combined with assessment of nine transient numerical groundwater models against observations, suggests the best conceptualizations are those where hydraulic conductivity and specific yield are distributed within a weathered zone determined through interpolation of weathered zone thickness. When compared to previous studies, the general groundwater balance of simulated models suggests the groundwater system contributes, on average, 49.8 m3 s−1 to the river flow (mostly during the rainy season). The same volumetric flow would be lost to groundwater evapo-transpiration and deep/lateral drainage of the catchment. Borehole abstraction (about 7.5 m3 s−1) represents only 6% of the average groundwater recharge and 1% of the average rainfall. This suggests that despite relatively low borehole productivity, the basement aquifer system still has an important unused potential for rural to mid-scale water supply and that, at present, the main external drivers for groundwater resource sustainability are changes in climate and land use.

The project is developed in the Sahel region of Burkina Faso, where a set of high resolution synthetic aperture radar (SAR) images was acquired. The rationale of the project along with the preliminary results obtained by the processing of high resolution Cosmo-SkyMed data are presented and discussed.

The main purpose is the extraction of land cover indexes for hydrology applications. The calibration procedure was implemented in a rural context in Burkina Faso, where along with the technical challenges we faced socio-economic problems. A set of handmade trihedral corner reflectors were deployed and their response measured from SAR images. The results were used for calibration of an erosion product.

Purpose of this paper is to present an approach to exploit high resolution SAR data for monitoring the temporal evolution of reservoir characteristics in semi-ardi regions. Classical and innovative techniques are tailored on the specific climatic conditions of these regions, characterized by the alternation of a three months wet and a nine months dry seasons. Results from a case study developed in Burkina Faso show that the combined use of amplitude and phase information allows the estimation of the eroded areas and a meaningful monitoring of the reservoirs sedimentation.

Les solutions de mitigation des effets nefastes de la secheresse sont proposees. Pour ce qui concerne les ressources en eau de surface et eau souterraine, les digues filtrantes et autres retenues d'eau permettent de concentrer les ecoulements des eaux de surface pour les differents usages; ce qui a pour consequences, une infiltration plus accrue et une recharge plus importante de la nappe souterraine. De nombreux travaux concourent a decrire le paradoxe sahelien, qui designe le fait que pendant cette pejoration climatique, certaines nappes d'eau souterraine ont vu leur niveau augmenter dans les bas-fonds alors que les pluies sont plus faibles et le ruissellement plus intense. La presente etude montre que dans le Sahel Burkinabe, lorsque le contexte geologique est sub-affleurant et la mi...
