Detailed Water Resources Studies of the Wasia-Biyadh Aquifer

Arabie Saoudite

Titre : Detailed Water Resources Studies of the Wasia-Biyadh Aquifer

Pays : Saudi Arabia

Lead executing agency : Ministry of Water and Electricity
Commissioned by : Ministry of Water and Electricity
Financier : Ministry of Water and Electricity

Overall term : June 2008 – May 2011

Despite the region’s arid climate, the Kingdom of Saudi Arabia has vast groundwater reservoirs nationwide. The Ministry of Water and Electricity (MOWE) is eager for detailed knowledge about all groundwater resources in the country. As MOWE aims to develop a sustainable long-term water usage and storage strategy, it requires reliable data about the volume, distribution and quality of groundwater resources. The Wasia-Biyadh Aquifer System, which is the subject of this ongoing project, is one of the largest water reservoirs in the kingdom.

The study area covers large parts of eastern Saudi Arabia between latitudes 16° and 31° north and longitudes 41° and 51° east. The following results will be submitted to the ministry when the project ends :
1. A Hydrometeorological Monitoring Network will be revised and installed by GTZ. It is a technical system, which monitors groundwater level and quality as well as climate conditions, and is equipped with telemetric data transmission systems.
2. A Water Resources Database will store all data and information acquired during the course of the project in a structured and user-oriented manner. The database will be managed in a GIS environment, which will be useful for future data analyses, visualisation and generation of thematic maps, charts and graphs.
3. A 3-D groundwater flow model will include the Wasia-Biyadh and overlying Aruma aquifers and will be coupled with the results of a complex rainfall-runoff-recharge model. New exploration drilling and testing will provide data for hydrostratigraphic units that form the basis for a valid conceptual groundwater model.
