Abstract



It is a known fact that apparent resistivity values above the water level are affected by seasons [5]. It is therefore the aim of this paper is to confirm this effect in Rapele and to show that the lithology derived from the resistivity values for both wet and dry seasons are the same. Vertical electrical soundings (VES) using the Schlumberger array were conducted in the wet and dry seasons in one station and the linear filter method was used in the interpretation of the resistivity soundings. The results were accurate and they showed the same number of layers (same curve shape) and approximately the same layer thicknesses.
