Zusammenfassung |
In addition to precautionary or technical flood protection measures,
short-term strategies of the operational management, i.e. the initiation and
co-ordination of preventive measures during and/or before a flood event are
crucially for the reduction of the flood damages. This applies especially for
extreme flood events. These events are rare, but may cause a protection
measure to be overtopped or even to fail and be destroyed. In such extreme
cases, reliable decisions must be made and emergency measures need to be
carried out to prevent even larger damages from occurring.
Based on improved methods for meteorological and hydrological modelling a
range of (physically based) extreme flood scenarios can be derived from
historical events by modification of air temperature and humidity, shifting
of weather fields and recombination of flood relevant event characteristics.
By coupling the large scale models with hydraulic and geotechnical models,
the whole flood-process-chain can be analysed right down to the local scale.
With the developed GIS-based tools for hydraulic modelling FlowGIS
and the Dike-Information-System, (IS-dikes) it is possible to quantify the
endangering shortly before or even during a flood event, so the decision
makers can evaluate possible options for action in operational mode. |
