A new database for flood fatalities and evacuation

A new database for flood fatalities and evacuationAfter a demonstration during the life loss modelling workshop in Toronto in June of this year, the flood fatality database is now online. A flood fatality database has been built in order to reduce life loss by evacuation and improve fatality functions and thereby evacuation planning and risk assessments. This open access database hosted by Delft University, stores historic flood event data on the hazard, impacts, preparedness and response. Also new events can be added to the database.

Researchers and authorities are encouraged to adopt this database, use the data in it and add new events. This will result in better data to improve research and policy, it will also enable others to benefit from the data as well and to study relevant factors for life loss and successful evacuation.

Floods still cause significant societal disruption in many countries resulting in high damages and many fatalities. To use the experience of events, their data must be stored and shared. In order to expand research on flood fatalities a flood event database has been developed that will help to identify relevant factors and the way they relate to flood fatalities. This will support the improvement of flood evacuation planning, flood emergency management and flood risk assessments.

Data of the number of fatalities, their age, gender and location as well information on the maximum flood level are usually collected after a flood. Information about the evacuation process (decision making, warning / communication etc.) and human behaviour are more scarce. Especially the latter type of empirical data could help to increase the effectiveness of flood emergency management further by better communication en evacuation planning. Therefore this information should be gathered as well when new floods (or flood threats) take place.

The database contains data related to flood hazards, flood mortality, house strength/collapse and human response (evacuation and rescue). It contains data on large scale, but can also store detailed GIS maps and data per household or object. The database can be accessed, used and filled from: http://floodfatalities.tudelft.nl/floodfatality/

The role of HKV was to develop and fill the database. We worked together in this project with Rijkswaterstaat, Deltares and Delft University. For more information about this database you can contact Bas Kolen per e-mail or by phone +31 320 294231.
