Abstract
The studied corridor, part of the Main Ethiopian Rift, has been delineated so as to include eastern and western escarpment, floor of the rift, and the Lakes Ziway & Koka Dam. All of which has the total aerial coverage of almost 6000 sq. Km. Geological coverage of the studied area is dominated by Lacustrine deposit at the floor of the rift, which is followed by other sub formation. Integrated methodology and approaches are conducted to observe the groundwater flow system and to determine hydrochemistry (water potablity) of the corridor. Both of which are interrelated each other and brought the same output. Groundwater flow system are considered as shallow and deep aquifer cases and the output indicate that the existence of flows in a separate way in the two systems. For the deeper case, groundwater migrates from southern to northern part of the study corridor which is disproving/ rejecting the previous work. For the shallower case, groundwater migrates from north western to south eastern of the corridor. Hydrochemical data shows: evolution of major ions, water types, potablity of water for human consumption, fluoride lateral & vertical distribution, which is the main problem in the Ethiopian Rift, and direction of groundwater flow. Graphical presentations of the physical and chemical parameters of the water samples provide a good deal of information on the characteristics of ground water flow systems, recharge and discharge zones, and evolution of major ions in the corridor. Appropriate software like Global Mapper, Surfer, ArcView, Aquifer Test, Aquachem, AutoCad and others employed to facilitate analyses and interpretations of the data in order to get the output.
