dc.description.abstract | This thesis presents results of geophysical and hydrogeological investigations
for groundwater' in the Lake Kenyatta settlement scheme: Lamu District, Coast
Province: Kenya. During the Pleistocene; the area was a beach and had sand
dunes which have since been eroded and filled up with sand giving the present
undulating relief. Inversia'n of ground resistivity sounding data yields resistivities
and thicknesses that are consistent with geology. The area consists mostly
of highly fissured coral limestone 5-30 m thick underlying a low resistivity substratum
comprising sands: clays, sandy clays and clayey sands. The deeper coral
limestone layers show consistent low resistivities, perhaps due to hard water in
the solution caverns. The geoelectric sections reveal a pinch and swell structure
of the coral limestone underlain by marine sediments. The freshwater/saltwater
interface consistently displays an undulating wavy structure at a de:.,',h of 20 to
40 m below the ground surface and extends over the entire area. | en |
