Risk-based assessment of drainage systems
Improving the method of dimensioning drainage systems for railway systems
The Austrian Federal Railways seeks to optimize their drainage systems for new railway tracks in order to minimize the negative impacts in case of flooding and to optimize land consumption. Therefore, the ILF Consulting Engineers Austria and as sub-contractor the alpS GmbH were engaged to develop a new risk-based approach to assess and design drainage basins of railway infrastructure. The alpS GmbH is responsible for the development of an innovative and new design approach which follows the principle of risk-based assessment, sustainability, and climate resilience. The new approach takes into account possible scenarios based on long time series of rainfall events and the advantages and disadvantages are assessed.
