The influence of added mass on rock block uplift in plunge pools

Anton Schleiss, Erik Bollaert, Matteo Paolo Elia Antonio Federspiel

Within the fluvial network, confluences are particular areas characterized by great ecological value where flow dynamics and bed morphology are much influenced by local patterns. The aim of this article is to describe the influence of the convergence angle ...

Effects of High Angular Momentum on the Unimolecular Dissociation of CD2CD2OH: Theory and Comparisons with Experiment

Michele Ceriotti

This paper explores the dynamics of a highly rotationally and vibrationally excited radical, CD2CD2OH. The radical is produced from the 193 nm photodissociation of 2-bromoethanol-d(4), so it is imparted with high angular momentum and high vibrational energ ...

Effect of available entrainable material on a viscous gravity current including run-out characteristics and internal flow properties.

Christophe Ancey, Belinda Margaret Bates

It has long been accepted that entrainment of loose material by geophysical gravity flows such as dense snow avalanches and debris flows may change their behaviour significantly. Run-out distances and bulk-flow velocities are notable examples of susceptibl ...

Accurate drainage network extraction and monitoring in a high-mountain catchment

Andrea Rinaldo, Marc Parlange, Raphaël Mutzner

We study the accuracy of channel network extraction methods obtained in two subcatchments of an alpine watershed in Switzerland and compare the results to the ones obtained with the real network, carefully monitored with a high precision DGPS during Summer ...

Temporal evolution of bedload in a steep channel over a long duration experiment

Anton Schleiss, Mário Jorge Rodrigues Pereira Da Franca, Tamara Ghilardi

Bedload fluctuations over time in steep rivers with wide grain size distributions have been observed, even under constant sediment feeding and water discharge. Observed bedload pulses are periodical and a consequence of grain sorting. Along with bedload, f ...

Geomorphic signatures of deltaic processes and vegetation: The Ganges-Brahmaputra-Jamuna case study

Andrea Rinaldo

Deltas are complex ecogeomorphic systems where features such as channels and interchannel islands are present over a wide range of spatial scales. A quantitative description of the morphology of deltas is fundamental to address how they react to changes in ...

Solute and sediment transport at laboratory and field scale: Contributions of J.-Y. Parlange

David Andrew Barry, Seifeddine Jomaa

We explore selected aspects of J.-Y. Parlange’s contributions to hydrological transport of solutes and sediments, including both the laboratory and field scales. At the laboratory scale, he provided numerous approximations for solute transport accounting f ...

Headwaters are critical reservoirs of microbial diversity for fluvial networks

Tom Ian Battin, Enrico Bertuzzo

Streams and rivers form conspicuous networks on the Earth and are among nature's most effective integrators. Their dendritic structure reaches into the terrestrial landscape and accumulates water and sediment en route from abundant headwater streams to a s ...

Reduction of bend scour with an air-bubble screen - morphology and flow patterns

Anton Schleiss, Koen Blanckaert, Violaine Dugué

The interplay between streamwise flow, curvature-induced secondary flow, sediment transport and bed morphology leads to the formation of a typical bar-pool bed morphology in open-channel bends. The associated scour at the outer bank and deposition at the i ...
