Modélisation de l 'impact prévisionnel sur l'hydrogéologie et l'hydrochimie d'une exploitation d'uranium en Namibie.
Résumé
The objective of this study is to build a hydrogeologic model which enables us to determine the potential disturbance caused by an uranium open cast mine in Trekkopje area (Namibia). Indeed during the mining operations, it is necessary to know if the pits will be flooded and in this case to evaluate the exhaust flow. After the mining, the pit will be backfilled with spend ore. It is therefore required to estimate the influence of the embankments on the flow and also to assess the risk of possible pollution of the aquifer, by coupling the geochemical data to the hydrogeological model
