Novel use of social media to assess and improve coastal flood forecasts and hazard alerts

Abstract Coastal communities and infrastructure need protection from flooding and wave overtopping events. Assessment of hazard prediction methods, used in sea defence design, defence performance inspections and forecasting services, requires observations at the land-sea interface but these are rare...
