Background• Jordan is one of the water scarcest countries with only 145 m3
/cap/year of renewable freshwater resources
• Most water is demanded by agriculture, especially in the Jordan Valley• According to Jordan's water strategy (2008-2022) a 503 MCM of water for 2020
is expected • Since 2004 there has been an increase of population with a rate of 2.2%• Groundwater levels are decreasing as a product of overexploitation (Fig. 2)
Objective
• Utilization of IWRM indicators ⇒ determine and quantify the possible impact of alternative water allocation options such as the implementation of new technologies like:
- brackish groundwater desalination
- decentralized wastewater treatment
Electrical conductivity (EC) profiles have been made in observation wells to show its variation along the depth.Values found in the Jordan Valley classify the water as brakish (Fig. 6).
Additional Field Work
• This model will be used as a reference for the regional up-scaling study of the IWRM-strategy for the Lower Jordan Valley.
• Values of electrical conductivity show a high salt content in the water of the Lower Jordan Valley as a consequence of overexploitation of ground-water resources and geological formation.
• Generally, results gained from models depend strongly on available input values and therefore, data preprocessing and consistency is necessary to ensure an acceptable accuracy.
• More measurements, especially concerning water quality parameters, will be carried out in the field in order to characterize the sub-basin as complete as possible and to calibrate the model.

The aim of this work is to support the implementation of the regional IWRM approach by the application of a holistic and integrated water planning case study at the sub-basin scale of Wadi Shueib.
Methodology• Coupling MODFLOW with WEAP ⇒ aggregated water balance in the
Wadi Shueib and downstream at the Jordan Valley (Fig. 4 and 5).
• Analyze water availability, utilization and demand while including the groundwater component.
