Evolutionary trends of the Niger Delta shoreline during the last 100Â years: Responses to rainfall and river discharge

Strong correlations between: shoreline change and the river discharge (R2 = 0.95), shoreline change and rainfall variability (R2 = 0.8), and rainfall variability and river discharge (R2 = 0.63) further confirm that shoreline changes of the delta during the last 100 years have been influenced by the variations in river discharge and rainfall, which are ultimately driven by climate change. It is therefore concluded that shoreline changes during the last 100 years along the Niger Delta coast have been influenced by rainfall variability and the resultant river discharge variations, which are ultimately driven by the regional climate change.
