Coastal Risk: Advance or Retreat
Flood inundation or coastal erosion by the sea pose major social and economic threats. This paper examines recent advances in the assessment of coastal risk related to extreme sea levels, wave run-up and overtopping, breaching, and erosion. Tsunami modelling and flood warning systems are discussed. A focused wave group methodology is introduced for the estimation of extreme storm waves. Improved statistical models based on joint probability distributions are leading to better estimates of extreme sea levels and coastal erosion. The reliability of flood risk maps will benefit from improvements in breach and inundation modelling.
