FLOODsite task 19Frameworks for flood event management
13 February 2006 Science Task Review 2
Task 17 scope of workReview flood Decision Support SystemsMethodological FrameworkImplementation of prototype DSSsApplication to pilots:
Thames Estuary (UK)Schelde estuary (NL)Nice (F)
13 February 2006 Science Task Review 3
Review of existing DSSsLimited number of DSSs for flood eventmanagement, more for long term flood riskmanagementAll have some GIS features, some GISbasedMost use pre-cooked model results
13 February 2006 Science Task Review 4
User requirementsPresent results of flood scenariosFlood hazard at vulnerable locationsPeople and objects at riskSafe havens and exit routesCoordination of all event responsepersonnelStorage of other relevant site-specific dataUser-friendly in terms of presentation ofresults

Exposure module
Vulnerability module
Hazard module
Risk module
Provision of Information to Decision Makers
Fluvial / tidal water levelsBreach locations and growth
Flood characteristics (depth, velocity, extent)
PeopleLivestock
Property and utilitiesTransport network
Expected damage for a forecasted water levelsummed over the different breach locations
expressed in euros or number of people harmed
Consequence moduleDamage to inhabitants (affected people,
exposed people, casualties)Damage to livestock, property and utilities
(expressed in the value lost)
Relation between flood characteristics anddamage for different receptors

Conclusions and recommendationsEnd-users support development of DSSsspecific for flood event managementCurrent prototypes should be furtherdeveloped to become operational toolsA dynamic link with an evacuation modelimproves evacuation planningGroundwater and flow through buildingsshould be incorporated into 2D floodmodels for evacuation planning
