River Krems flood protection

Project description

In previous years the river Krems  repeatedly overflowed its river banks and caused catastrophic flood damages.

  • It was deemed necessary to provide flood protection for a 100 year flood event.
  • Preservation of multifunctionality of the river Krems where it flowed through urban areas was necessary.

Over 6km of flood protection measures were constructed, with the majority located in a dense settled town area (city infrastructure, limited space availability, varied usage demands on urban river waters) and it puts specific demands on the design and construction.

  • Rehabilitation and an increased elevation of existing river walls as well as river bed sealing and construction of flood protection walls in the area of existing dams.
  • River construction measures as optimisation of the river bed slope and the adjustment of corss sectional flow areas in order to meet hydraulic, ecological and urban demands.
  • Construction of flood protection walls with removeable barriers for access to the river.
  • Construction of 3 new bridges an footbridges.
  • The removal of two wiers and the installation of fish passes.
  • The adaption of existing transport and services infrastructure.
  • Renaturalisation of the existing "hard" river bed and adjacent overflow areas.
