Project duration: 02/2019 - 03/2020
Key characteristics: 2D- hydraulics
The city of Balingen is hosting the garden show in 2023. The planning concept provides for new and redesigned open spaces along the Eyach and Steinach rivers between Erdingen and Schmiden. Hydraulic proof was provided for the redesigns in the watercourse and river environment to ensure that the structural changes do not lead to a deterioration in runoff conditions or an aggravation of the flooding problem.
In the flood protection concept with associated river basin study in the entire catchment area of the Eyach, which was completed at the beginning of 2019, flood protection in different variants in Balingen was conceptually investigated using hydrological and hydraulic modeling. Findings on a minimum required line protection were taken over from the river basin study in advance and incorporated in the form of cross profile adjustments.
In the course of this project, ecological measures were implemented in the watercourse and near-watercourse areas and flood protection was designed for the new water level levels.
The detailed plans of the planned measures were elaborated and provided by external landscape planners. These were transferred into the 2D model.
The HQ100 scenario and a HQ100 climate scenario with a factor of 1.15 were investigated.
Furthermore, the changed retention area volume due to the implemented measures was balanced.
