Rehabilitation of the retention area Oberfüllbruch
Table of contents
Brief description
As part of the renovation of the Oberfüllbruch retention area, a weir will be built in the right-hand dam of the Pfinz relief canal as an inlet structure. The Oberfüllbruch retention area is to be filled in a controlled manner via the new intake structure. Physical model tests were carried out for the intake structure to ensure its hydraulic capabilities and subsequent operation. Unfavourable hydraulic effects were determined and optimizations regarding the control of the structure were developed. In addition, the type and quality of energy conversion downstream of the structure was investigated and evaluated.
The true-to-scale modeling (M 1:20) of the terrain cubature and the technical structures was carried out according to Froude's law of similarity. This was followed by the model tests with detailed data acquisition and data evaluation as well as the creation of a numerical 3D HN model for improved flow visualization. The main focus of the investigations was on determining the discharge characteristics at the inflatable weir and the bed load in the downstream water of the weir system.
