Spatial characterization of catchment dispersion mechanisms in an urban context

Previous studies have examined in-depth the dispersion mechanisms in natural catchments. In contrast, these dispersion mechanisms have been studied little in urban catchments, where artificial transport elements and morphological arrangements are expected ...

Model simulations of the modulating effect of the snow cover in a rain-on-snow event

Michael Lehning, Nander Wever, Charles Fierz, Tobias Jonas

In October 2011, the Swiss Alps underwent a marked rain-on-snow (ROS) event when a large snowfall on 8 and 9 October was followed by intense rain on 10 October. This resulted in severe flooding in some parts of Switzerland. Model simulations were carried o ...

Time Dependent Failure Analysis of Compressed Riprap as Riverbank Protection

Anton Schleiss, Michael Pfister, Mona Jafarnejad Chaghooshi

Riprap is a common measure for protecting river banks against lateral erosion and several methods exist to design them. However, they are generally limited to dumped medium size rocks. If large rock blocks are required for stability reasons, they cannot be ...

Flow processes near smooth and rough (concave) outer banks in curved open channels

Anton Schleiss, Koen Blanckaert, Alexandre José Pessanha De Oliveira Caimoto Duarte

Flow processes near the (concave) outer bank in curved river reaches are investigated in a laboratory flume, with focus on the influence of the bank roughness. An outer-bank cell of reversed secondary flow occurs for all the investigated roughness configur ...

Mechanisms of vegetation uprooting by flow in alluvial non-cohesive sediment

Paolo Perona, Katharina Maria Edmaier

The establishment of riparian pioneer vegetation is of crucial importance within river restoration projects. After germination or vegetative reproduction on river bars juvenile plants are often exposed to mortality by uprooting caused by floods. At later s ...

Effects of the foot evolution on the behaviour of slow-moving landslides

Alessio Ferrari, David Gonzalez

The paper presents a time-dependent 2D numerical model which has been developed with the purpose of highlighting the effects of the slope foot evolution on the behaviour of slow-moving landslides. The model allows to quantitatively analyse how foot mass va ...

Soil erosion under multiple time-varying rainfall events

David Andrew Barry, Seifeddine Jomaa

Soil erosion is a function of many factors and process interactions. An erosion event produces changes in surface soil properties such as texture and hydraulic conductivity. These changes in turn alter the erosion response to subsequent events. Laboratory- ...

Research on eco-hydro-morphological river processes by combining field investigations, physical modeling and numerical simulations

Koen Blanckaert, Violaine Dugué, Alexandre José Pessanha De Oliveira Caimoto Duarte, Ana Margarida Da Costa Ricardo

Hydrodynamical, morphodynamical and ecological river processes and their multiple linkages occur in an infinity of different configurations and over a wide range of spatial and temporal scales. This paper illustrates a research methodology that consists in ...

Fabrication of microfluidic mixers with varying topography in glass using the powder blasting process

Martinus Gijs, Abdeljalil Sayah, Virendra Kumar Parashar

The powder-blasting method is used to fabricate structures with a three-dimensional topography in glass using elastomeric masks. The relation between the mask opening width and the erosion depth is exploited to fabricate microstructures with varying depth ...
