Modeling Groundwater Flow of the Mio-Pliocene Aquifer in the El-Outaya Plain, Biskra (Algeria)
Keywords:
Modeling, free groundwater, calibration, groundwater assessment, managementAbstract
El Outaya plain is located on the southern flank of the Aures Mountains, as part of ??the Saharan Atlas. It has an arid climate (less than 200 mm of rainfall / year). The Mio-Pliocene aquifer associated with this plain is an important resource for irrigation and drinking water.
Achieving the first hydrodynamic model of the Mio-Pliocene ground water in El Outaya plain, with different operating scenarios and using the Visual Mod-flow code, shall contribute to the development of an action plan for a rational management of water resources.
In addition, the model was calibrated to steady state conditions and then transient state conditions in order to prepare conductivity and porosity maps that characterize the spatial variability, in relation with the geological heterogeneity of the aquifer. Different operating scenarios indicated that the northern part of the plain is fairly vulnerable to feeding and exploitation conditions.
