Al-Fat'ha formation at mishraq structure considered from the hydrogeological point of view as one of the most complicated multiple aquifer, where containing cavities and the water zones formed by the action of dissolution and alteration of evaporate rocks to sulphur, the thickness ranges from 1 m to 10 m and their number exceeding 10 zones. Temp. profiles were observed in 20 hydrogeological boreholes to locate the distribution of water bearing zone vertically by the infection in the temp. profiles
Temp profiles are classified into four types according to their patterns of variation in temperature gradient with depth. It has been found the degree of inflection and the changes in temperature gradient have a relation with the hydraulic properties and ground water movement horizontally and vertically between the aquifers.
