Abstract

Al Maqam-AI Saad area is located to the west of Al Ain city on Al Ain-Abu Dhabi

Highway. This area was chosen to be studied because of the rapid decline of the

water level in the shallow aquifer as a result of continuous heavy withdrawal of the

ground water. In 1990-1991, the area was recognized as one of the major ground

water depressions in the Eastern Region where more than 40 meters of draw down

were noted in the center of depression . The objective of this study is to determine the

hydraulic status of the aquifer by means of characterization and to carry out a

quantitative assessment of the shallow aquifer in the study area.

The characterization of the aquifer was conducted in order to assess the hydraulic

conductivity in the area by means of re-analysis of previously conducted pumping tests.

Pumping tests conducted in the area by the Ground-water Research Program (GWRP)

were reanalyzed using Aquifer Test Software. The results of the reanalysis are displayed

in maps of transmissivity and hydraulic conductivity. The hydraulic conductivity in the

area is small and ranges from 1 to 5 meters per day with increasing trend from east to

west. This range of values is consistent with the heterogeneous lithology of the

aquifer that ranges from well sorted to poorly sorted gravel inter bedded with clay

')

stone, siltstones, shale, and limestone. In addition to the pumping tests analysis,

geological intonation and ground-water salinity distribution maps were also taken into

Consideration In the aquifer characterization and hence in the aquifer as assessment
