This book provides a comprehensive description of groundwater
resources in Ethiopia and its various dimensions (groundwater as
resource, environmental functions, and socioeconomics). The
prevailing knowledge of groundwater resources in Ethiopia (or
elsewhere in Sub Saharan Africa) was based on geological and
stratigraphic framework known nearly four decades ago (mainly
1960's and 70's). Thanks to the substantial geoscientific research
since the 70's a new set of relevant geological/stratigrahpic data
has been created that helps to re-define our understanding of
groundwater resources in Africa as a whole and in Ethiopia in
particular: a) For the first time the basement aquifer of Ethiopia
has been described hydrogeologically based on genesis of regoliths
(deep weathering and striping history); clear regional difference
in groundwater potential is shown for the first time; comparative
accounty has been given regarding groundwater occurrence in the
generally low grade basement rocks of Ethiopia (Arabian Nubian
shield) and high grade basement rocks of the rest of Africa. b) For
the first time groundwater occurrence in multilayred sedimentary
rocks account for spatial variation in degree of karstification;
deformation history, and stratigraphy. c) The vast volcanic
aquifers of Ethiopia which have previously classified based on
their ages are now reclassified based on age, morphology (eg.
groundwater in plateau volcanics, groundwater in shield volcanics)
and aquifer structure. d) The loose alluvio lacustrine sediments
which were known as least extensive in previous works based on
areal cover are in fact shown to host the most voluminous
groundwater resources in Ethiopia. These aquifers have now been
described based on their geomorphology, extent, and genesis. The
aim of this book is to use these newly created knowledge to
redefine the understanding of groundwater resources in Ethiopia.
