Experimental Study on Dam-Break Waves for Silted-Up Reservoirs

Anton Schleiss, Rafael Xavier Meriade Duarte

The overall dam-break phenomenon is currently well understood for reservoirs filled with water. However, many dams face serious problems of reservoir sedimentation. Thus, regarding risk management, the influence of a large amount of sediment in the reservo ...

Experimental investigation of the bedload transport and anti-dunes over a steep bed.

Christophe Ancey, Joris Heyman, François Mettra

This poster present an experimental investigation of bedload transport in steep slope streams. Accurate technics are used to measure bed elevation and sediment transport rate. The data shows the dynamics of antidunes and the stochastic behavior of bedload ...

Experiments on turbulence and settling down of fine sediments induced by pumped storage operations in a cuboidal reservoir

Giovanni De Cesare, Michael Müller

Long-term sedimentation of pumped storage reservoirs due to the alternation of turbine and pumping modes is an issue regarding sustainability and reliability of such schemes. Systematic experiments on a cuboidal basin are conducted to study how flow fields ...

Flow separation in sharp meander bends

Koen Blanckaert

It is well known that abrupt changes in flow direction may lead to flow separation from boundaries. While many smaller or confined meandering rivers have bends sharp enough for flow separation, the problem has surprisingly been ignored in the meandering li ...

Hypolimnetic oxygen consumption by sediment-based reduced substances in former eutrophic lakes

Alfred Johny Wüest, Beat Mueller, Martin Schmid

We quantified the areal hypolimnetic mineralization rate (AHM; total areal hypolimnetic oxygen depletion including the formation of reduced substances) in two formerly eutrophic lakes based on 20 yr of water-column data collected during oligotrophication. ...

Evaluating oxygen fluxes using microprofiles from both sides of the sediment-water interface

Alfred Johny Wüest

Sediment-water fluxes are influenced by both hydrodynamics and sediment biogeochemical processes. However, fluxes at the sediment-water interface (SWI) are almost always analyzed from either a water-or sediment-side perspective. This study expands on previ ...

One-Dimensional Numerical Modelling Of Mobile Bed Evolution In A Flume With A Side Weir

Anton Schleiss, Burkhard Rosier

Side weirs are widely used to control flow processes along a channel or river. The lateral loss of water reduces the sediment transport capacity in the main-channel leading to local sediment deposition near the overflow. The design discharge to be diverted ...

Channel formation during flushing of large shallow reservoirs with different geometries

Anton Schleiss, Sameh Ahmad Kantoush

Depositional and flow patterns are first described to gain an understanding of the erosion patterns during hydraulic flushing in a reservoir. Considering the importance of this issue, two modes of flushing operation for control of sedimentation were perfor ...

Modulation of electron transport during Swing ECCD discharges in TCV

Olivier Sauter, Timothy Goodman, Stefano Alberti, Costanza Zucca

Generation of a swing electron cyclotron current drive (swing ECCD), i.e. driving alternated, symmetric, positive or negative local ECCD, during a single discharge and at constant total input EC power, was performed at the Tokamak a Configuration Variable ...
