Variable sediment oxygen uptake in response to dynamic forcing

Seiche-induced turbulence and the vertical distribution of dissolved oxygen above and within the sediment were analyzed to evaluate the sediment oxygen uptake rate (J(O2)), diffusive boundary layer thickness (delta(DBL)), and sediment oxic zone depth (z(ma ...

Numerical simulation of two-phase flow for sediment transport in the inner-surf and swash zones

David Andrew Barry, Roham Bakhtyar

A two-dimensional two-phase flow framework for fluid- sediment flow simulation in the surf and swash zones was described. Propagation, breaking, uprush and backwash of waves on sloping beaches were studied numerically with an emphasis on fluid hydrodynamic ...

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 ...

Physical and numerical modeling of harbors and shore protection measures / Modélisation physique et numérique de mesures de protection portuaires et d’aménagement de plages

Azin Amini, Fadi Hachem

The expansion project of the ‘’Port de la Nautique’’ and the creation of adjacent new beaches on the ‘’Lac Léman’’ in Geneva is currently under survey. In the conceptual and study phase, numerical- and physicalscaled models have been exploited at the Ecole ...

Transport in the hydrologic response: Travel time distributions, soil moisture dynamics, and the old water paradox

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

We propose a mathematical framework for the general definition and computation of travel time distributions defined by the closure of a catchment control volume, where the input flux is an arbitrary rainfall pattern and the output fluxes are green and blue ...

Two-phase hydrodynamic and sediment transport modeling of wave-generated sheet flow

David Andrew Barry, Roham Bakhtyar

This numerical investigation was carried out to advance mechanistic understanding of sediment transport under sheet flow conditions. An Euler-Euler coupled two-phase flow model was developed to simulate fluid-sediment oscillatory sheet flow. Since the conc ...

Considerations on rockfall hazard mapping based on trajectory modelling

Vincent Labiouse, Jacopo Maria Abbruzzese, Claire Sauthier

The paper presents first considerations about methodologies for local hazard mapping related to rockfalls. This work is being currently carried out at the Swiss Federal Institute of Technology of Lausanne (EPFL), and it concerns the ESR8 research position ...

An exact solution for ideal dam-break floods on steep slopes

Christophe Ancey, Martin Rentschler

Dam-break floods on steep slopes occur in diverse settings. They may result from failure of either natural or man-made dams, and they have been responsible for the loss of thousands of lives [Costa, 1988]. Recent disasters resulting from dam-break floods o ...
