Use of gas bubbles for ultrasound Doppler flow velocity profile measurement

Ultrasonic velocimetry based on the Doppler shift effect accurately provides quasi-instantaneous flow fields for fluids with a sufficiently high acoustic scattering level. However, ultrasonic velocity instruments are known to perform poorly in clear water ...

Reservoir sedimentation management at Gebidem Dam (Switzerland)

Tobias Meile

The Gebidem Dam located on the Massa River intercepts annually around 400’000 m3 of solid material. These sediments must be evacuated by annual flushing of the reservoir over 4 to 7 days. A trend for silting in the flushing channel was observed during the ...

Propagation of surge waves in channels with large-scale bank roughness

Anton Schleiss, Tobias Meile

elements. In addition to a prismatic reference channel, 41 different configurations of rectangular bank cavities have been investigated. The purpose was to study the effect of large-scale bank roughness on steady and unsteady flows. The macro-roughness of ...

Discussion “Propagation of surge waves in channels with large-scale bank roughness"

Anton Schleiss, Tobias Meile

In open channels, a sudden rise in water elevation generates a positive surge. Positive surges are commonly observed in man-made channels (Bazin 1865, Treske 1994) and a natural occurrence is the tidal bore in macro-tidal estuaries (Tricker 1965, Chanson 2 ...

Closure to "Propagation os surge waves in channels with large bank roughness

Anton Schleiss, Tobias Meile

The authors thank the discusser for his interest in our work and the complementary information on the behaviour of undular surges in a channel with a local rapid constriction and expansion. ...

Hydropeaking indicators for characterization of the Upper-Rhone River in Switzerland

Anton Schleiss, Tobias Meile

River channelization and the construction of high-head storage schemes have been the basis of agricultural and socio-economic development in many alpine regions. One example is the Upper-Rhone River in Switzerland. The Upper-Rhone's morphology changed cons ...

Water-surface oscillations in channels with axi-symetric cavities

Anton Schleiss, Tobias Meile

Transverse or longitudinal movements of a water body are observed for flows along cavities, river embayments, groyne fields or harbours. They are significant for certain flow conditions and geometrical properties. To study the effect of large-scale roughne ...

2D numerical flow modeling in a macro-rough channel

Anton Schleiss, Tobias Meile, Michel Pirotton

A 2D numerical flow model, developed at the Research unit of Hydrology, Applied Hydrodynamics and Hydraulic Constructions at ULg, has been applied to flows in a macro-rough channel. The model solves the shallow water equations (SWE) with a two length scale ...

Reduction of Hydropeaking in Rivers by Bank Macro Rroughness

Anton Schleiss, Tobias Meile

High-head storage hydropower plants operate their turbines during periods of high energy demand. The starting and stopping of turbines results in rapid fluctuations of discharge and water levels in rivers called hydropeaking, which are unfavourable from an ...
