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

Tobias Meile, Anton Schleiss

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"

Tobias Meile, Anton Schleiss

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 ...

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

Tobias Meile, Anton Schleiss

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

Tobias Meile, Anton Schleiss

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

Tobias Meile, Anton Schleiss, 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

Tobias Meile, Anton Schleiss

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 ...

Improvement of Acoustic Doppler Velocimetry in steady and unsteady turbulent open-channel flows by means of seeding with hydrogen bubbles

Giovanni De Cesare, Tobias Meile, Koen Blanckaert, Anton Schleiss

Velocimetry is used in various fields of research. In hydraulics, Ultrasonic Velocimetry based on the Doppler Shift effect can accurately resolve the quasi-instantaneous flow field [Takeda Y. Velocity profile measurement by Ultrasonic Doppler method. Exper ...

Influence of macro-roughness of walls on steady and unsteady flow in a channel

Tobias Meile

High-head storage hydropower plants mainly operate their turbines during periods of high energy demand. The sudden starting and stopping of turbines (hydropeaking) lead to highly unsteady flow in channels and rivers. Besides hydropeaking, other anthropogen ...
