Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 Floods are natural phenomena which cannot be prevented. Human activity is contributing to increasing in the likelihood and the adverse impacts of flood events. The challenge of flood risk management requires action at European, Member States and regional/river basin level. Flood Directive aims to reduce and manage the flood risks to human health, environment, infrastructure and property. Introduction Rome 23rd October 2009
Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 The FD requires Member States to first carry out a preliminary assessment by 2011 which shall include (art. 4): (a) a map of the river basin district including the borders of the river basins, subbasins and where appropriate associated coastal zones, showing topography and land use; (b) a description of the floods which have occurred in the past; (c) a description of flooding processes and their sensitivity to change, including the role of flood plain areas as a natural retention/buffer of floods and flood conveyance routes now or in the future; (d) a description of development plans that would entail a change of land use or of allocation of the population and distribution of economic activities resulting in an increase of flood risks in the area itself or in upstream or downstream regions; (e) an assessment of the likelihood of future floods based on hydrological data, types of floods and the projected impact of climate change and land use trends; (f) a forecast of the estimated consequences of future floods to human health, the environment and economic activity taking into account long-term developments including climate change. So far, there is no comprehensive and consistent “European” database on past flood events and their impacts. Flood Directive: preliminary assessment
Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 ETC SIA – coordinated by EEA and JRC - has started an informal survey which was sent in April 2011 to all EEA member countries; Aim: Obtain an overview of existing databases on past flood events and their impacts at Member State level; The survey focuses on metadata, including information on impacts. Survey Questionnaire
Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 • Author • name and institution of compiler; • Generalities • country, DB name, accessibility, date of creation, updating frequency and last update; • Characteristics of DB • format, type of information, map scale, description of data collection; • Content of DB • content, type of information, threshold/criteria, # of records, information on impacts; • Additional information
Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 Answers to questionnaire 11 countries out of 32 have answered; Some of them has more than one DB.

Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 Updating Frequency Most countries show a high frequency of DB updating.

Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 Contents of DB Number of records depends on threshold criteria.
Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 Information on Impacts 8 out of 11 member countries record impacts of flood events.
Expert meeting on hazard/disaster data: EU Flood information CRED, Brussels, 19th May 2011 • many EEA member countries have already started a collection of information about past flood events and their economic and social impacts; this information covers a widespread part of the European territory with a sufficient temporal coverage; • only half of the member countries which responded have collected spatial (raster/vector) data for each event; • a few member countries use a specific entry thresholds for events to be recorded. The use of such a threshold has a significant influence on the number of recorded events (low threshold = large number of events); • data comparison between data sets from different countries might be rather difficult, given the heterogeneity of the existing databases. Thus, in the view of a European database, some steps towards a common understanding, e.g. including common criteria in both data collection and representation (e.g. map scales, data attributes, hydrological data …) as well as thresholds might be needed; • some national databases are already fully publicly accessible, some other are accessible under restrictions. Improving public data accessibility will be a challenge in the future. Final remarks and comments
