Overview

Investigates coastal erosion in West Africa, highlighting the need for adaptive protection strategies.

Key Points

  • This research aims to examine the effects of climate change and human interventions on the West African coastline, focusing on erosion and coastal management.
  • Field measurements of shoreline changes
  • Multi-temporal satellite imagery analysis from 2005 to 2023
  • UAV surveys for accurate data collection
  • Sediment grain-size analysis to understand transport dynamics
  • Numerical modeling using one-line models and finite difference methods
  • Significant shoreline retreat and accretion patterns identified
  • Port jetties and breakwaters disrupt longshore sediment transport
  • Numerical models effectively predict long-term coastal behavior in data-scarce regions
