Periodic flushing operations during moderate flood events (≤annual flood flow HQ1) are an approach to counteract problems caused by disturbed sediment continuity in rivers, which is possibly an effect of run-of-river hydropower plants (RoR-HPPs). C

The newly developed Archimedean double screw hydropower concept combines hydroelectric power generation and bi-directional fish passage in a single device. Efficiency tests were conducted at the first commercial facility to verify the design data. Th

A systematic variation of the exposure level of a spherical particle in an array of multiple spheres in a high Reynolds number turbulent open-channel flow regime was investigated while using the Large Eddy Simulation method. Our numerical study analy

Run-of-river hydropower plants (RoR HPPs) are capable of interrupting the sediment connectivity of many alpine rivers. Still, there is a lack of systematical investigations of possible sediment management strategies for small and medium sized RoR HPP

This study concerns scaled physical model tests of the delta formation process at the head of a run-of-river hydropower plant (RoR). It forms part of a larger research project to provide a scientific base for RoR sediment management strategies in med

ZusammenfassungIn den Flüssen der Böhmischen Masse stellt ein unausgewogenes Sedimentregime in Form eines Sedimentüberschusses zunehmend ein Problem dar. Die vorherrschenden Korngrößenfraktionen (d = 1 bis 10 mm) sind ungeeignete Lebensräume u.

The vortex shedding topology of a heavy pendulum oscillating in a dense fluid is investigated using time-resolved three-dimensional particle tracking velocimetry (tr-3-D-PTV). A series of experiments with eight different solid to fluid mass ratios $m

This study presents experimental investigations of entrainment events of a single sediment particle resting in a small pocket on a smooth bed in an open channel flow. The data were acquired with a ...

Large physical experiments require - among others - scaling of channel geometry and sediments in order to fit to the available laboratory infrastructure. In this study, scaling effects were investigated with the help of a 3D numerical model (RSim-3D)
