This paper illustrates the practicality and efficiency of gravimetry
for aquifer prospecting in arid zones. Known for the long and tedious
data-processing it requires, this method becomes expeditious when
simplified as presented here. Its use is then fully justified in
a survey of this kind.
During the study of the Teloua alluvial aquifer (Agadez, Niger), several
ancient channels were clearly and rapidly located. Comparison of
the results obtained here with those from previous studies demonstrates
anew that for comprehensive prospecting, several complementary geophysical
methods should always be employed.
