Hydrogeological caracterization and modeling of the aquifer of oued in amguel. (Tamanrasset, Central Hoggar - South Algeria)

Abstract

The region of In Amguel takes its water from a single groundwater resource known in the Hoggar by "the inferoflux water table", captured by an underground dams with a  capacity of 4 Hm3 realised in 2000. This aquifer is highly exploited for supply drinking water and agriculture which create big deficit of water demand. Also, for better  management of this inféroflux, we realized its hydrogeological model by using the computer code ASMWIN, allowing us to better understand the hydrodynamic   functioning, refine the distribution of spatial characteristics governing groundwater flow in steady state and transient and conduct simulations of the behavior of the system for different operating scenarios.
