Model-based investigation on the hydraulic conditions at the Twistetal dam

Table of contents
Short description
The project aims to ensure the hydraulic capabilities of the Twist dam after a change of the water-side shut-off devices and to evaluate the function of the stilling basin with regard to a possible complete dismantling of the jet riprap. For this purpose, a three-dimensional hydronumerical (3D-HN) model was developed in OpenFOAM®.
With the help of this model, 3D-HN simulations were carried out to investigate the hydraulic situation for different flow rates (Q1, Q2, Q3). The spillway was not loaded in the process. In addition, the actual state with existing jet riprap was simulated in order to analyze the effects of a later removal for a specific flow (BHQ). Finally, the model was adapted for the complete removal of the jet riprap and a further calculation was carried out to evaluate the stilling basin at a relevant BHQ.
