Iullemeden Aquifer System: Hydrogeological Model - Volume III

The hydrogeological modelling undertaken under the project “Managing hydrogeological risks in the Iullemeden Aquifer System (SAI)” is part of the Transboundary Diagnostic Analysis (TDA). His goal is to better assess water resources of this aquifer system and to identify hydrogeological risks associated.

OSS has proposed to carry out this model with the national team’s contribution in view to provide to the three countries a powerful tool for managing the shared water resources. This is a critical analysis of available information and identifying its practical limitations in improving knowledge about the behaviour of the aquifer system and the identification of hydrogeological risks associated to the water resource abstraction increasingly intensive.

This document presents a hydrogeological water balance of the aquifer system with its different components: recharge, hydrogeological characteristics (structure, hydraulic head, and water quality), abstraction and seepage.

Using the model as a tool for simulation of the aquifer system can develop scenarios for developing its water resources. It allows to reach the planning goals in the three countries and to identify the impact of withdrawals on the aquifer system behaviour and risks trends.

This document is a summary of the effort made by the project team at OSS and national experts associated in the collection, formatting relevant data for modelling and conceptualization of the hydrodynamic behaviour of this system, and its connections with the environment.
