Ecomorphodynamic approaches to river anabranching patterns

We investigate the influence of vegetation on river morphological instabilities using an analytical framework. We first discuss the important role of the hydrological (flooding frequency) and biological (vegetation development rate) timescales. As long as ...

Hydro-morphodynamics of open-channel confluences with low discharge ratio and dominant tributary sediment supply

Sebastián Guillén Ludeña

River confluences in which the tributary supplies the dominant sediment load, and the flow discharge is abundantly provided by the main river, are typically observed in mountain-river basins. The existent knowledge on the hydrodynamic, morphodynamic and se ...

Radiation reaction induced non-monotonic features in runaway electron distributions

Joan Decker

Runaway electrons, which are generated in a plasma where the induced electric field exceeds a certain critical value, can reach very high energies in the MeV range. For such energetic electrons, radiative losses will contribute significantly to the momentu ...

Comparison of chute aerator effect on stepped and smooth spillways

Anton Schleiss, Michael Pfister, Stéphane Christian Olivier Terrier

Bottom chute aerators are installed to prevent cavitation damages and they have been studied in detail on smooth spillways. In parallel, stepped spillways became widespread in the past decades. Research has shown that stepped spillways may be endangered ev ...

Effects of the Discharge Parameters on the Efficiency and Stability of Ambient Metastable-Induced Desorption Ionization

Xiao Sheng Zhang, Mario Andres Chavarria Varon

Ionization efficiency is an important factor for ion sources in mass spectrometry and ion mobility spectrometry. Using helium as the discharge gas, acetone as the sample, and high-field asymmetric ion mobility spectrometry (FAIMS) as the ion detection meth ...

Industrial plasmas in academia

Christoph Hollenstein, Ivo Furno, Alan Howling, Philippe Frédérique Bruno Guittienne

The present review, written at the occasion of the 2014 EPS Innovation award, will give a short overview of the research and development of industrial plasmas within the last 30 years and will also provide a first glimpse into future developments of this i ...

Hydro-morphodynamic differences induced by different angles in an experimental discordant confluence

Sebastián Guillén Ludeña

Confluences, within the fluvial network, are considered particular areas with great ecological value, where flow dynamics and bed morphology are complex and highly three-dimensional. Several parameters influence the morphodynamics and hydrodynamics of rive ...

Granulation of snow: From tumbler experiments to discrete element simulations

Michael Lehning, Johan Alexandre Philippe Gaume, Betty Sovilla, Walter Steinkogler

It is well known that snow avalanches exhibit granulation phenomena, i.e., the formation of large and apparently stable snow granules during the flow. The size distribution of the granules has an influence on flow behavior which, in turn, affects runout di ...

Effect of compressed riprap thickness on the stability of river banks

Anton Schleiss, Michael Pfister, Mário Jorge Rodrigues Pereira Da Franca, Mona Jafarnejad Chaghooshi

One of the common measures for river bank protection is the installation of riprap. There are several methods to design riprap appropriately, which are however generally limited to dumped medium size blocks. Nevertheless, an additional resistance against e ...
