dc.description.abstract |
Non-destructive subsurface exploration methods could reveal subterranean
characteristics with minimal consumption of time and resources. However, validity
of such interpretations could vary depending on the appropriate use of the
controllable parameters in the geophysical method, with respect to the subsurface
complexities. Accordingly, this study evaluates the sub subsurface characteristics of
several locations revealed by the interpretation of resistivity data to understand the
performance of different electrode configurations used in resistivity surveying. The
electrode spacings maintained at each configuration was also critically assessed to
identify the most appropriate for a particular instance of surveying. Furthermore,
subsurface profiles were computed using three different interpretation methods to
identify any influences from the interpretation method on the accuracy of the
resultant profile. The results reveal a strong dependency of interpretations on the
array configuration and maintained electrode spacing. And it was determined a
suitable electrode spacing for improved subsurface interpretation. In order to
improve accuracy of interpretations, it also suggests the need of developing an
upper limit for current electrode spacing (AB) of the Schlumberger Array
Configuration, given the general electrode spacing is maintaining a lower limit as
AB > 5 (potential electrode spacing). |
