Schadensmodelle für extreme Hochwasser - Teil 2: Erste Schlussfolgerungen aus dem Ereignis vom Juni 2013

Damage models for extreme flood events - Part 2: Preliminary conclusions from the event in June 2013

The 2013 flood event caused severe damage again in the areas affected by the 2002 flood. Based on a damage documentation along the river basin of Vereinigte Mulde and Zwickauer Mulde, and therefore concentrated on the most affected areas during the flood in Saxony, some preliminary conclusions are drawn about the impact of two extreme floods on a repeated affected building stock.
The evaluation of the observed damages allows a further plausibility of the flood damage model which was developed at the Earthquake Damage Analysis Center (EDAC) at the Bauhaus-Universität Weimar.
In the study areas Döbeln, Eilenburg and Grimma in Saxony, already affected by the 2002 flood, the observed damages and the flood heights are documented. Newly developed vulnerability and damage functions enable the prediction of the damages and losses, which can be correlated later with the official reported losses.
The effects of recovery measures after the 2002 flood on the vulnerability of the building stock are highlighted and the resulting changes are taken into account differentiated by the prediction of the losses.
