Abstract

The Albaji alluvial plain lies in the Persian Gulf desert belt and on the north west of Ahvaz. From a structural point of view the plain is an enclosed basin and is surrounded by Karkheh and Karun rivers. Groundwater salinity is high and electrical conductivity (EC) varies between 2000 and 75000 µmohos/cm2. In order to evaluate groundwater quality of the Albaji aquifer, factors and processes governing chemical characteristics of water resources were taken into consideration. Graphic methods and necessary maps were used to assess quality behaviors. The results indicated that various factors including, basinal sedimentation condition of water bearing layer, water and aquifer content materials interaction, evaporation, irrigation recharge water and recharge from Karkheh river influencing groundwater quality of the alluvial aquifer. The data also depicted that among the influencing components the first one is dominant agent.
