International Conference on Case Histories in Geotechnical Engineering
Erosion occasioned by annual floods along the Cross River at Unwana Beach, Afikpo, situated on latitude 8° 00’ 00’’ North of the Equator and longitude 5° 40’ 15’’ East of the Greenwich Meridian, has threatened the location of a Water Pumping and Treatment Station nearby. Geotechnical investigations carried out using the Shell-and-Auger rig along the shoreline of the Unwana Beach indicated that the subsurface consists of between 3.00 to 8.00 meters of Yellowish brown silty clay layer (CL) underlain by about 3.00 meters of Dark, clayey sands (SC). These are further underlain by between 0.00 – 4.00 meters of Reddish …
