| Zusammenfassung |
| Models for estimating flood losses to infrastructure are rare and their reliability is seldom
investigated although infrastructure losses might contribute considerably to the overall flood
losses. In this case study, a statistical modelling approach for estimating direct structural
flood damage to railway infrastructure and associated financial losses was developed. Via a
combination of empirical data, i.e. photo-documented damage on the Northern
Railway in Lower Austria caused by the March river flood in 2006, and simulated
flood characteristics, i.e. water levels, flow velocities and combinations thereof, the
correlations between physical flood impact parameters and damage occurred to
infrastructure were investigated and subsequently rendered into a damage model. After
calibrating the loss estimation using recorded repair costs of the Austrian Federal
Railways (ÖBB), the model was applied to three synthetic scenarios with return
periods of 30, 100 and 300 years of March river flooding. Finally, the model results
were compared to depth-damage curves for the infrastructure sector obtained from
literature.
In this contribution, the methodology, results and evaluations for the developed flood
damage model will be presented and initial conclusions for flood loss estimation to railway
transportation will be drawn.
This case study is part of the ENHANCE-project, funded by the 7th EU Framework
Programme. |
