Replenishment of sediment downstream of dams

Dams on rivers alter the sediment continuum, trapping water and sediment in the upstream reservoirs. River reaches downstream are affected by several negative effects, such as bed incision, reduction of the river morphological variability, development of a ...

Canopy wake measurements using multiple scanning wind LiDARs

Fernando Porté Agel, Corey Dean Markfort, Giacomo Valerio Iungo, Fernando Carbajo Fuertes

Canopy wakes have been shown, in controlled wind tunnel experiments, to significantly affect the fluxes of momentum, heat and other scalars at the land and water surface over distances of O(1 km), see Markfort et al. (EFM, 2013). However, there are current ...

Producing synthetic natural gas from microalgae via supercritical water gasification: A techno-economic sensitivity analysis

Christian Ludwig, Frédéric Vogel, Martin Brandenberger

A techno-economic sensitivity analysis of the production of synthetic natural gas (SNG) via catalytic supercritical water gasification (SCWG) of microalgae produced in raceway ponds (RP), tubular-, or flat-panel-airlift photobioreactors (FPA-PBR) has been ...

Lab on a chip technologies for algae detection: a review

Yves Bellouard

Over the last few decades, lab on a chip technologies have emerged as powerful tools for high-accuracy diagnosis with minute quantities of liquid and as tools for exploring cell properties in general. In this paper, we present a review of the current statu ...

Steep flume experiments with large immobile boulders and wide grain size distribution as encountered in alpine torrents

Anton Schleiss, Tamara Ghilardi

Flow conditions and sediment transport capacity in steep mountain rivers are poorly known. One of the main problems is that the presence of macro-roughness elements, such as large relatively immobile boulders, have a strong influence. Experiments carried o ...

Cascade Pericyclic Reactions of Alleno-Acetylenes: Facile Access to Highly Substituted Cyclobutene, Dendralene, Pentalene, and Indene Skeletons

Pablo Rivera Fuentes

The allene core of 1,3-di-tert-butyl-1,3-diethynylallenes has been shown in the past to be essentially unreactive. However, its inherent reactivity could be unleashed by the introduction of tailored substituents to induce a variety of highly selective reac ...

Modelling natural disturbances in forest ecosystems: a review

François Gillet

Natural disturbances play a key role in ecosystem dynamics and are important factors for sustainable forest ecosystem management. Quantitative models are frequently employed to tackle the complexities associated with disturbance processes. Here we review t ...

Wave induced velocities inside a model seagrass bed

Laboratory measurements reveal the flow structure within and above a model seagrass meadow (dynamically similar to Zostera marina) forced by progressive waves. Despite being driven by purely oscillatory flow, a mean current in the direction of wave propaga ...

Analyse et exploitation des données de LIDAR aéroportés pour la caractérisation des milieux boisés de la Suisse

Gilles Gachet

Forest ecosystems show diverse and evolving structures. Accurate descriptions and a good knowledge of these environments are therefore a real challenge. Existing forest cover investigation methods are mostly laborious, hard to replicate and usually based o ...

GIS modelling of forest wood residues potential for energy use based on forest inventory data: Methodological approach and case study application

Edgard Gnansounou, Luis Alberto Panichelli

This paper presents an approach to perform geo-referenced estimations of forest wood residues availability for energy use based on forest inventory data integration into a GIS. Three different estimation methods are described. The first one evaluates bioma ...
