- Abstract
The aim of this study is to investigate the tablecloth behaviour of High Bandama basin for the best management of groundwater. It was based on satellite Landsat TM images and piezometric data acquired during three campaigns (August 2009, April 2010, and May 2012) exploitation. Thus, the statistical analysis of fracturing shows that the main direction of fracturing is N0-10 with 14 percent. The most secondary direction is N70-80 with eight percent. These directions should allow water infiltration. Piezometric study reveals that seasonal variations of ranges do not exceed 4 meters unlike the structures of Dassoumgbo, Sépénédiokaha, and Fonnikaha (Côte d'Ivoire) which register respectively negatives variations of -4 m, -5.06 m and -5.485 m. At the opposite, there are small positives variations of water level ranging from +0.025 m (Koutiénédougou) to +0.9 m (M'bolokakaha). They highlight some weak water upwelling levels and thus show that the tablecloth reaction is not immediate after the rainy season. These upwellings are gradual and seem to reflect difficult conditions of groundwater supply. The interannual ranges of the aquifer during the three campaigns are less than 5.5 meters. Piezometric map sketch during the high flow and less flow of water doesn't reveal some notice variations. The overlaying of the density map fracturing and the piezometric variations map for points followed during August 2009 and April 2010 campaigns shows that it is difficult to establish a relationship between piezometric and fracturing. This study constitutes important support for groundwater resource management in the basin.
