A 2D electrical resistivity survey using the Wenner-Schlumberger array was conducted at four sites in Jesse town, Delta State, Nigeria. The goal was to identify potential subsurface features, like an ancient buried stream, linked to ongoing road pavement failures. Data collected with a Petro Zenith Earth Resistivity meter were processed using RES2DINV software. Results revealed low-resistivity anomalies in Locations 1 and 2, interpreted as possible fractures or a buried paleochannel. Specifically, anomalies at ~45m and 60m in Location 1 and around 50m in Location 2 suggest zones where water inflow could weather the underlying laterite, contributing to pavement failure. These interpretations are preliminary and require validation through drilling or hydrogeological investigation to confirm the causes of the anomalies.
