dc.description.abstract | This thesis describes the results of a resistivity study
performed in the period September, 1987 - September, 1988 in the
Isenya area, some 56 Krn south. of Nairobi, Kenya. The main
objective of the study was to delineate aquifers for the purpose
of groundwater development in the area.
A total of 60 vertical electrical soundings (VES) were made
using the Schlumberger configuration.About 80% of these provided
good data.
The results of the soundings reveal a close correlation
between the geoelectric layers and the artificial groundwater
(outcrops' as well as the geology of the area. A hydrogeological
basin trending NW-SE has been delineated both in terms of
geometry and extent. This trend coincides with the structural
trend and strongly suggests that the groundwater flow is
structurally controlled.
For further groundwater development in the Isenya area it is
recommended that boreholes for groundwater abstraction be sited
within this basin and preferably along the structural lines. This
basin appears to be the area of the highest groundwater potential. | en |
