Coastal erosion investigation using electrical resistivity and remote sensing along the coastline of Bayelsa State, Nigeria

Coastal erosion is a serious issue in the coastal communities of Bayelsa State. The soil components and vegetative cover along the shoreline or close to the shoreline were studied using electrical resistivity and remote sensing. Data acquisition was done with resistivity meter and adoption of google earth. In the study area, some locations were made up of high resistivity values in the top soil while in other areas low resistivity values in the top soil meaning different soil compositions. Areas of high erosional activities like Sangana were of low resistivity in the top soil. It was noted that areas of high erosion were connected to sparse vegetative cover. It was recommended that continuous or time dependent study be always conducted in the area to know the trend of events in the area concerning coastal erosion.
