دراسة هيدروجيولوجية للمنطقة المحصورة بين طريق نجف-كربلاء

Abstract EN

The area which located along the road between the Karbalaa and Najaf cities is one of the important areas in terms of hydrogeological view due to containing the groundwater reservoirs of sandy Debdebba and Dammam limestone formations.

The exposed part of the Sandy Debdibba formation helps to renew its water and maintenance of groundwater storage through the infiltration of rainfall and surface floods.

The groundwater movement in this reservoir flows from west towards east and south-east direction, while the quality of groundwater in this reservoir is characterized to be highly concentrated with dissolved salts which are generally ranged between (2000) to (4700) PPM.

The Dammam Formation is consider as an aquifer in this area where its western hydraulic boundary characterized to be continuous underground water movement coming from west and south -west direction of the Western Desert.

Most of formation thickness considered being saturated thickness of reservoir due to containing wide and expanded caves and cracks as a result of structural and weathering impact.

These factors helped to expand cracks on formation exposed surface as well as caves inside it.

The Groundwater movement in this aquifer flows from west towards Euphrates River.

The salinity of groundwater in this reservoir is varied ranging between (1900) to (3700) PPM with calcium sulfate type.
