Natural attenuation of arsenic by sediment sorption and oxidation
Arsenic sorption onto aquifer sediments was investigated in anaerobic laboratory batch and column uptake experiments and characterized by As, Fe, and Mn X-ray absorption spectroscopy (XAS) to estimate the extent and mechanism of abiotic sorption and oxidat ...
2009One-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 ...
2009Saturation of curvature-induced secondary flow, energy losses, and turbulence in sharp open-channel bends: Laboratory experiments, analysis, and modeling
The paper investigates the influence of relative bend curvature on secondary flow, energy losses, and turbulence in sharp open-channel bends. These processes are important in natural streams with respect to sediment transport, the bathymetry and planimetry ...
2009Process-based model for nearshore hydrodynamics, sediment transport and morphological evolution in the surf and swash zones
David Andrew Barry, Roham Bakhtyar
Nearshore hydrodynamics and sediment transport in the nearshore zone were modeled numerically taking into account turbulent unsteady flow. The flow field was computed using the Reynolds Av-eraged Navier-Stokes equations with a k-ε turbulence closure model, ...
2009Modeling sediment transport in the swash zone: A review
David Andrew Barry, Roham Bakhtyar
A critical review of conceptual and mathematical models developed in recent decades on sediment transport in the swash zone is presented. Numerous studies of the hydrodynamics and sediment transport in the swash zone in recent years have pointed out the im ...
2009Parameter 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 ...
2009Transport of suspended sediment under the dam-break flow on an inclined plane bed of arbitrary slope
The problem of transport of suspended sediment after the break of a dam on an inclined bed is considered. To that end we use the shallow-water approximation for arbitrary, constant slopes of the bottom, taking into consideration the effect of friction. The ...
2008Experimental study on the influence of the geometry of shallow reservoirs on flow patterns and sedimentation by suspended sediments
The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...
EPFL2008Experimental study on the influence of the geometry of shallow reservoirs on flow patterns and sedimentation by suspended sediments
Anton Schleiss, Sameh Ahmad Kantoush
The worst enemy of sustainable use of reservoirs is sedimentation. Often the main silting process is the result of settling down of suspended sediments. In shallow reservoirs the flow pattern and the sediment deposition processes are strongly influenced by ...
EPFL-LCH2008Evolution of sediment deposition and flow patterns in a rectangular shallow reservoir under suspended sediment load
Anton Schleiss, Sameh Ahmad Kantoush
The deposition behavior of fine sediment is an important phenomenon, which remains unclear to engineers concerned about reservoir sedimentation. In the present case bed level changes, suspended sediment concentrations, and flow velocities were measured in ...
