Field characterization of the negatively buoyant inflow of the Rhône River into Lake Geneva

David Andrew Barry, Ulrich Lemmin, Koen Blanckaert

River inflows have a major influence on lake and reservoir water quality through their input of momentum, heat, oxygen, sediment, nutrients and contaminants. The fate of these components is controlled by the hydrodynamic processes at the interface between ...

Quasi-stationary flow structure in turbidity currents

Giovanni De Cesare, Shun Nomura

A turbidity current is a particle-laden current driven by density differences due to suspended sediment particles. Turbidity currents can transport large amounts of sediment down slopes over great distances, and play a significant role in fluvial, lake and ...

Hypolimnetic oxygen depletion rates in deep lakes: Effects of trophic state and organic matter accumulation

Robert Vincent Schwefel, Beat Mueller

This study investigated the consumption of oxygen (O-2) in 11 European lakes ranging from 48 m to 372 m deep. In lakes less than similar to 100 m deep, the main pathways for O-2 consumption were organic matter (OM) mineralization at the sediment surface an ...

The performance of collars on scour reduction at tandem piers aligned with different skew angles

Anton Schleiss, Giovanni De Cesare, Sargol Memar

Local scouring is a leading cause of bridge collapses. To protect bridges against local scouring, different countermeasures have been proposed and tested in the literature. In this study, the performance of collars was evaluated for scour reduction at two ...

Innovative methods to release fine sediments from reservoirs developed at EPFL, Switzerland

Anton Schleiss, Giovanni De Cesare, Pedro Filipe De Almeida Manso, Azin Amini, Sabine Chamoun

Electricity generation, water supply, flood protection, flow regulation and navigation are amongst the main services provided by reservoirs. Sedimentation affects the sustainability of reservoirs, by reducing their storage capacity, and increases the negat ...

Interplay of S and As in Mekong Delta sediments during redox oscillations

Rizlan Bernier-Latmani, Laurent Louis José Charlet

The cumulative effects of periodic redox cycling on the mobility of As, Fe, and S from alluvial sediment to groundwater were investigated in bioreactor experiments. Two particular sediments from the alluvial floodplain of the Mekong Delta River were invest ...

Floodplain Land Cover and Flow Hydrodynamic Control of Overbank Sedimentation in Compound Channel Flows

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Carmelo Juez Jiménez, Hannes Jenny

Overbank sedimentation is predominantly due to fine sediments transported under suspension that become trapped and settle in floodplains when high-flow conditions occur in rivers. In a compound channel, the processes of exchanging water and fine sediments ...

Multidecadal sediment balance modelling of a cascade of alpine reservoirs and perspectives based on climate warming

Anton Schleiss, Pedro Filipe De Almeida Manso, Sebastián Guillén Ludeña

This paper presents a comprehensive methodology to model and determine the annual sediment balance of a complex system of interconnected reservoirs, based on the detailed interpretation of a multi-decadal data series of reservoir management and modelling o ...
