INTEGRATED METHODS USING MULTICHANNEL ANALYSIS OF SURFACE WAVES (MASW) AND ELECTRICAL RESISTIVITY TOMOGRAPHY (ERT) FOR GEOTECHNICAL HAZARD ASSESSMENT (A Case Study of Queen Ede, Benin City, Edo State)
Gully erosion has been among the most serious environmental and geotechnical risks within the southeastern part of Nigeria, which endangers infrastructure, livelihood, and sustainable land use. This paper discusses the use of an integrated geophysical technique that consists of Electrical Resistivity Tomography (ERT) a...
