Flood protection in Kulmbach
Start of the 2nd construction phase
In the past, the Purbach stream has often caused flooding in the Blaich district of the town of Kulmbach in eastern Germany. In order to prevent future flood damage, the water flowing off the surface is to be collected and fed underground to the White Main river.
The first construction phase of this project has already been completed. As part of the currently ongoing second construction phase, installation of bored piles was carried out in July 2021. The routing of the diverted water through a new culvert beneath various traffic areas, connecting to the White Main, will ensure the safe discharge of floodwater in the future. Inros Lackner is supporting the project in the role of General Planner.
The culvert, of rectangular cross section, was designed for HQ100 = 11.0 m³/s on the basis of a 2D hydraulic calculation. The construction of the culvert, of total length 486 m, is being carried out in an open trench. Following completion of construction and backfilling of the excavations, the traffic routes on the surface will be restored. As part of this, the Blaich road intersection will be replaced by a roundabout, enabling traffic flows to be better regulated.
