| Zusammenfassung |
| After the extreme flood event of the Elbe in 2002 the definition of flood
risk areas by law and their simulation became more important in Germany.
This paper describes a concept of an analysis framework to improve the
localisation and duration of validity of flood inundation maps. The
two-dimensional finite difference model TrimR2D is used and linked to a
Monte-Carlo routine for parameter sampling as well as to selected
performance measures. The purpose is the investigation of the impact of
different spatial resolutions and the influence of changing land uses in the
simulation of flood inundation areas. The technical assembling of the
framework is realised and beside the model calibration, first tests with
different parameter ranges were done. Preliminary results show good
correlations with observed data, but the investigation of shifting land uses
reflects only poor changes in the flood extension. |
