The book summarizes research work on the Wajid Sandstone, which provides integrated field and laboratory data to enable a detailed description of this unit including a facies analysis, porosity data, as well as permeability data to establish aquifer models. Detailed facies analysis at outcrop scale are supported by vertical and lateral sedimentological sections, facies and environmental analysis and supplemented by detailed laboratory petrographical and petrophysical data. The analysis and interpretation of the outcrop analog models include the reconstruction of the stratigraphic architecture at outcrop scale. Moreover, the results were described statistically, analyzed and eventually establish an outcrop-based aquifer model analogue. The book benefits undergraduate, graduate and researchers working on applied sedimentological studies, hydrogeology, statistical and geostatistical analysis and modeling.

The book gives an outline of prevailing hydrogeologic conditions in the Arab Middle East together with the geologic background. Emphasis is given to relationships between the main features influencing the hydrogeologic conditions - regional geologic developments, paleogeographic conditions, morphology, climate and paleo-climate - and the resulting hydrogeologic features: formation of aquifers, distribution of major aquifers, main groundwater flow systems, occurrence of renewable and fossil groundwater. Reported data on hydraulic aquifer parameters, recharge rates and groundwater flow volumes are evaluated with a view to arrive at characteristic values under the specific hydrogeologic and climatic conditions. The area considered covers approximately the Arabian Plate. Information on the following countries is included: Bahrain, Iraq, Jordan, Kuwait, Lebanon, Oman, Qatar, Saudi Arabia, Syria, United Arab Emirates, West Bank and Gaza, Yemen.
