This aquifer could be easily accessible with rudimentary structures such as sumps and could constitute a supplementary water source, for irrigation activities in this second region of Burkina Faso.
From a hydrogeological point of view, downstream of the study area, the alluvial plain would constitute toographie important aquifer with a high porosity and thick deposits. As expected, the flat slab region is impacted by colder temperatures, and therefore by faster seismic velocities and more intense seismic activity, compared to the normal slab region.
HagedornJudith Ellen Devaney Thursday, March 13, – 5: The alluvial plain would be relatively thicker downstream of the study area approximately 30 to 50m. Thursday, December 12, – 1: GeorgeJohn G.
We show evidence that the flat slab dehydrates within the mantle wedge, but also along the subducting ridge prior to re-subducting.
Ray tracing graphics Parallel computing Computation. We show the most complete regional 3-D seismic tomography images of this region, whereby, in comparison to previous studies, we use 1 a much larger seismic dataset l from several short-term seismic catalogs, 2 a sismkque denser seismic station network which enables us to resolve better the subduction zone.
