An integrative and applied pilot study
The Disaster Information System for Large-Scale Flood Events Using Earth Observation (DISFLOOD) is a platform for multi-disciplinary and multi-institutional research. DISFLOOD is a pilot study that combines different methods like remote sensing, hydraulic hazard models, and economic damage models with social and ecological vulnerability indicators.
DISFLOOD provides an overview on flood risk of affected human population and environment by easy accessible and comprehensive maps.
Mapping Disaster Risk in Germany
The overall objective of DISFLOOD is the development of a Disaster Information System (DIS) providing a multi-disciplinary flood risk assessment for Germany. In different work packages techniques and methods are identified that (1) facilitate the assessment of vulnerability, (2) create large-scale flood event sets and (3) derive flood hazard maps from remote sensing data. Maps and information will be provided in a Geographical Information System (GIS) and are supposed to contribute to disaster risk reduction. The combination and integration of methods from social and natural science are the main challenge in this project, but are necessary to enhance an integrative risk assessment. DISFLOOD works on a regional scale and seeks to provide data and methods that can be applied for whole Germany.

Objectives
|
|
The objective of DISFLOOD is to provide a Disaster Information System which offers valuable information on flood risk, vulnerability and damage depending on different flood hazard scenarios. The information system will be realised in an interactive WebGIS format which will be implemented on the Helmholtz-EOS NaDiNe platform. The framework of DISFLOOD comprises two elements, which cover different stages on the flood disaster (or management) cycle. One element of the methodological work in DISFLOOD is the flood risk assessment. It is based on different hazard scenarios, for example the 2002 and 2006 Elbe floods as mapped by satellite remote sensing technology or calculated from water gauges using a hydraulic modelling approach as well as on synthetically modelled flood scenarios. The second element of DISFLOOD is the rapid assessment of potential economic damages as well as human and ecological exposure in case of a real flood event, based on satellite derived inundation areas.
