Mapping and Analysis of the Impact of Coastal Erosion Using Remote Sensing: A case Study of Port Harcourt Coastline

Abstract

This study has been able display the usefulness of remote sensing and GIS technologies in mapping and analysis of coastal erosion in Port Harcourt, Rivers State. The results revealed that between 2010 and 2014, coastal erosion had a trend growth of 9.40%, this indicates that the annual rate of growth of coastal erosion between said year is 2.35% per year.
