Development Challenges

West Africa’s coastlines are undergoing rapid morphological changes. Close to 68% of sandy beaches in the sub-region are being eroded at an average rate of two (2) meters per annum with low lying areas perennially inundated (World Bank, 2016). This is further compounded by sea water intrusion leading to the pollution of coastal fresh water, decreasing soil fertility and destruction of biodiversity.

There is lack of scientific data on coastal degradation at national and regional levels for forecasting coastal evolution, limited historical time-series data as well as inadequate expertise (e.g. modellers) in various technical areas (e.g. engineering) to resolve coastal geomorphology and engineering problems.

Objectives

  • To evaluate the impact of wave climate on beach morphology
  • To forecast wave climate variation
  • To understand the design and consequences of coastal structures
  • Develop models on coastal dynamics for the Africa region
  • To explore the relationship between climatic factors(temperature, rainfall, wind etc) anomaly and coastal disasters

Research Areas

  • Coastal hydrodynamics
  • Salt water intrusion
  • Transport and mixing processes
  • Flood risks
  • Coastal sediments and sediment transport
  • Coastal morphology
  • Coastal protection and engineering

Expected Outcomes

  • Baseline model developed for coastal changes
  • Hotspots for coastal erosion mapped
  • Developed guidelines to achieve resilient coastal systems
  • Capacity built in modelling climate variability
