a) For the 1st time the basement aquifer of Ethiopia has been defined hydrogeologically in response to genesis of regoliths (deep weathering and striping history); transparent neighborhood distinction in groundwater strength is proven for the 1st time; comparative accounty has been given relating to groundwater incidence within the quite often low grade basement rocks of Ethiopia (Arabian Nubian defend) and excessive grade basement rocks of the remainder of Africa.
b) For the 1st time groundwater incidence in multilayred sedimentary rocks account for spatial edition in measure of karstification; deformation historical past, and stratigraphy.
c) The colossal volcanic aquifers of Ethiopia that have formerly categorised in response to their a long time at the moment are reclassified in line with age, morphology (eg. groundwater in plateau volcanics, groundwater in defend volcanics) and aquifer constitution.
d) The free alluvio lacustrine sediments which have been often called least large in prior works in line with areal disguise are in reality proven to host the main voluminous groundwater assets in Ethiopia. those aquifers have now been defined according to their geomorphology, volume, and genesis.
