At the power plant Opponitz in Austria 2.3 km of tunnels were rehabilitated with glass-fibre reinforced plastic (GRP) pipes which were drawn into the original tunnel profile. Due to the reduction in cross-section this measure led to a considerable re

There is an enormous untapped potential for hydropower generation in rivers with large head and high flow variation, currently not feasible for conventional hydropower dams. Conventional dams make use of the potential energy, but waste kinetic energy

The determination of air entrainment in free falling water jets is still a topic subject to large uncertainties that eddy-viscosity model. The RANS turbulence model did not generate water separation from the water surface. However, the LES model was

Weir structures with underflow gates are used in channels, rivers or reservoirs to control water levels, such as keeping constant upstream water level. Designing control structures is a sensitive task, as their reliability influences not only the saf

The prediction of air entrainment in a free falling water jet (two-phase flow) is affected by large uncertainties. A current research project at the Vienna University of Technology is dealing with this phenomenon by means of experimental tests and CF

The following paper concerns the experimental investigation of hydrodynamic forces on a so-called "HYDROMATRIXModule" during different underflow conditions. This mobile module is shifted in place of the stoplog slots in a tainter gate bay of an ex
