Effect of raindrop splash and transversal width on soil erosion: Laboratory flume experiments and analysis with the Hairsine-Rose model

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

The parameter consistency of the one-dimensional Hairsine-Rose (H-R) erosion model under conditions of significant rainfall splash was examined. To account for the splash characteristic length scale and its interaction with the transverse erosion width, ex ...

Effect of stone coverage on soil erosion

David Andrew Barry, Alessandro Brovelli, Seifeddine Jomaa

Soil surface coverage has a significant impact on water infiltration, runoff and soil erosion yields. In particular, surface stones protect the soils from raindrop detachment, they retard the overland flow therefore decreasing its sediment transport capaci ...

Fish behavior during hydropeaking in a channel equipped with a lateral shelter

Anton Schleiss, Jean-Marc Ribi

In the framework of a research project focusing on mitigation measures for hydropeaking, a lateral embayment at the channel bank is studied as a fish refuge. Systematic experiments with different refuge configurations were carried out. The basic configurat ...

Reduced formulation of a steady fluid-structure interaction problem with parametric coupling

Gianluigi Rozza, Toni Mikael Lassila

We propose a two-fold approach to model reduction of fluid-structure interaction. The state equations for the fluid are solved with reduced basis methods. These are model reduction methods for parametric partial differential equations using well-chosen sna ...

Channel formation during flushing of large shallow reservoirs with different geometries

Anton Schleiss, Sameh Ahmad Kantoush

Depositional and flow patterns are first described to gain an understanding of the erosion patterns during hydraulic flushing in a reservoir. Considering the importance of this issue, two modes of flushing operation for control of sedimentation were perfor ...

One-Dimensional Hairsine-Rose Erosion Model: Parameter Consistency for Soil Erosion in the Presence of Rainfall Splash

David Andrew Barry, Seifeddine Jomaa

Process-based erosion modelling has proven to be an efficient tool for description and prediction of soil erosion and sediment transport. The one-dimensional Hairsine-Rose (HR) erosion model, which describes the time variation of suspended sediment concent ...

Parameter Changes from Upscaling of a Local Scale, Process-Based Erosion Model

David Andrew Barry, Seifeddine Jomaa

Soil erosion affects agricultural productivity, the natural environment and infrastructure security. Soil loss and its associated impacts are important environmental problems. Consequently, model-based predictions of erosion are beneficial for a variety of ...

One-Dimensional Numerical Modelling Of Mobile Bed Evolution In A Flume With A Side Weir

Anton Schleiss, Burkhard Rosier

Side weirs are widely used to control flow processes along a channel or river. The lateral loss of water reduces the sediment transport capacity in the main-channel leading to local sediment deposition near the overflow. The design discharge to be diverted ...

Inferences from catchment-scale tracer circulation experiments

Andrea Rinaldo, Enrico Bertuzzo, Gianluca Botter

In this paper the mechanisms determining the mobilization and transport of solutes driven by rainfall through runoff pathways at catchment scales are investigated through the analysis of tracer experiments. The hydro-chemical response of a small catchment ...
