Satellites, tweets, forecasts: the future of flood disaster management?
Résumé
Floods have devastating effects on lives and livelihoods around
the world. Structural flood defense measures such as dikes and
dams can help protect people. However, it is the emerging science
and technologies for flood disaster management and preparedness,
such as increasingly accurate flood early warning systems, highresolution satellite monitoring, rapid risk mapping, or the use of
social media information and crowdsourcing, which are most
promising for reducing the impacts of flooding. We propose here
a framework that combines the most recent advances in flood
early warning, monitoring, and mapping systems with the unique
strength of social media streaming and news monitoring in an
innovative knowledge trigger cycle. This will allow emergency
responders to have a broad range of timely and accurate
information available for more effective and robust planning,
decision-making, and resource allocation. The recent large-scale
flood event in France (2016) could be used to showcase the
proposed framework.
