Tractebel Hydroprojekt plans sustainable flood protection along the Hörsel, monitors the construction projects and takes over the ecological construction supervision.
The flooding caused considerable damage in Eisenach. Due to the increasing risk of flooding, the responsible Thuringian State Office for the Environment, Mining and Nature Conservation expects the risk of further flooding of large parts of the city. Therefore, the urban area receives a sustainable flood protection, which at the same time createst new habitats for flora and fauna.
The planned flood protection along the Hörsel is divided into five sections (measures complex MK I-V). The project is a top priority as part of the "FloodProtection Programme 2016 to 2021". The aim is to protect the entire urban area from a 100-year flood (HQ100). The river should lose its canal-like impression as far as possible and be renaturalized.
Modelling experience spaces by the river
Tractebel's hydraulic engineering experts received the first planning contract in 2010 for the MK I, and a year later for the MK II. Both have already been successfully completed. In 2019 and 2020, the team carried out the execution planning and construction preparation of MK II. Construction of this section is due to begin in autumn 2020.
Currently, the experienced engineers are tasked with planning the MK IV: Between the Wutha-Farnroda railway bridge and the Langensalzaer Straße bridge, various flood protection measures are planned. These include, among other things, new flood protection walls, the upgrading of existing dikes, Deichanlagen and a new bridge replacement. Terrain modelling and waterbody-widening will design the shore areas as living and experience spaces.
Focus on nature and species protection
For a total of three complexes, Tractebel is also responsible for ecological construction supervision. Our specialists monitor whether the implementation of the construction projects complies with legal regulations in accordance with the Federal Nature Conservation Act and whether species protection concerns are taken into account. They develop planning services under nature protection law and accompany the landscape management execution planning. The tasks also include applying for and organising the fishing necessary during the construction phase. Our Team is expected to complete its work in 2029.
