| Zusammenfassung |
| The analysis and management of flood risk commonly focuses on surface water
floods, because these types are often associated with high economic losses
due to damage to buildings and settlements. The rising groundwater as a
secondary effect of these floods induces additional damage, particularly in
the basements of buildings. Mostly, these losses remain underestimated,
because they are difficult to assess, especially for the entire building
stock of flood-prone urban areas. For this purpose an appropriate
methodology has been developed and lead to a groundwater damage simulation
model named GRUWAD. The overall methodology combines various engineering and
geoinformatic methods to calculate major damage processes by high groundwater
levels. It considers a classification of buildings by building types,
synthetic depth-damage functions for groundwater inundation as well as the
results of a groundwater-flow model. The modular structure of this procedure
can be adapted in the level of detail. Hence, the model allows damage
calculations from the local to the regional scale. Among others it can be
used to prepare risk maps, for ex-ante analysis of future risks, and to
simulate the effects of mitigation measures. Therefore, the model is a
multifarious tool for determining urban resilience with respect to high
groundwater levels. |
