Gro for GooD ERT (Electrical Resistivity Tomography) Data, Kwale County, Kenya (NERC grant NE/M008894/1)

Results of Electrical Resistivity Tomography (ERT) conducted in Kwale County, Kenya December 2015 and June 2016 by University of Nairobi and Water Resources Management Authority as part of the Gro for GooD project (https://upgro.org/consortium/gro-for-good/) to characterize the aquifers in the study area. There were eight transects of length 1.2 to 6km, running W-E and NNE-SSW parallel to coastline. ERT data was analysed using RES2D inversion software.

Statement
2-D electrical imaging/tomography survey equipment was used (Telford, 1990, Griffiths and Barker 1993). For history of ERT see Parasin, 1962. Field set of the tomography system used here included ABEM SAS 1000 Terrameter, LUND ES464 switchbox (electronic switching unit), four multi-core cables each with 21 current take out points at constant spacing of 10 metres interval, battery, communications cables, electrode jumpers, electrodes, laptop and data transfer cables. This dedicated equipment measures both ?V and I and presents a calculated apparent resistivity. The profile length was 800m and the investigated depth was 149m bgl. Roll-along technique was used. After completion of measurements, the cable was moved past one end of the line by two cables. Measurements which involved electrodes on one part of the cable which did not overlap the original end of the survey line were repeated.
