Flood protection Krems river

Tasks definition

In the previous years the Krems river repeatedly flowed over the river banks and caused catastrophic flood damages.

  • Protection against the hundred years flood was necessary.
  • Preservation of functional capability and multifunctionality of flowing waters in urban areas.

The entire project area (6,140 m) is located in a dense settled town area (city infrastructure, limited space availability, varied utilization demands on urban flowing waters) and it puts specific demands on planning and construction execution.

  • Rehabilitation and elevation of river side walls as well as bottom sealing and construction of flood protection walls in the area of existing dams.
  • River construction measures as optimalization of river bed slope and adjustment of flow affecting cross section respectively mean water channel to hydraulic, ecological and urban demands.
  • Renaturation of the weir system for an efficient streaming continuum and nature-oriented design of the river bed to get a heterogeneous water structure (ecological enhancement of the river Krems).
  • River flood plain in a form of a formed river bank board-walk as a new recreational area within easy reach of built-up areas for better quality of life.
