Large Scale Particle Image Velocimetry (LS-PIV) is used to measure the surface flow velocities in a mountain stream during high flow conditions due to a reservoir release. A complete installation including video acquisition from a mobile elevated viewpoint and artificial flow seeding has been developed and implemented. The LS-PIV method was adapted in order to take into account the specific constraints of these high flow conditions. Using a usual LS-PIV data processing, significant variations of ...

The current study tries a new approach to simulating interactions between waves and seagrass through Smoothed Particle Hydrodynamics (SPH). In this model, the plants are defined as a solid that respects Hooke's law, and are assumed to have direct interaction with the fluid. Given the characteristics of the SPH method, especially in terms of computational time, the dimensions of the simulations were limited. The first goal of the current study was to optimize the approach to avoid reaching certain ...

Comprehensive measurements of bed-load sediment transport through a section of the Danube River, located approximately 70 km downstream from Bratislava, Slovakia, are used to assess the accuracy of bed-load formulas implemented in 1D modeling. Depending on water discharge and water level, significant variations in the distribution of bed load across the section were observed. It appeared that, whatever the water discharge, the bed shear stress τ is always close to the estimated critical bed shear ...

Fixed side‐looking Doppler current profilers (H‐ADCP) recently emerged as an innovating technique for the continuous monitoring of river discharges. The discharge can be computed from the flow velocities measured by the H‐ADCP along a horizontal profile across the section. This paper reports a field assessment of the quality of velocities and discharges provided by a 3‐narrow‐beam Teledyne RD Instruments, Inc. (RDI) 300 kHz H‐ADCP installed at the Saint‐Georges gauging station (Saône river in Lyon, ...

In the last five years, horizontal acoustic Doppler current profilers have come onto the market as an instrument designed to measure real-time horizontal current profiles from a permanent fixed mount. The focus of this paper is on the feasibility of using these commercial instruments to measure suspended sediment fluxes in rivers. Measurements are presented from a study site that was equipped with an optical turbidity meter and three horizontal ADCPs operating at 300 kHz, 600 kHz and 1200 kHz between ...

In this paper, the results of a benchmark test launched within the framework of the NSF–PIRE project "Modelling of Flood Hazards and Geomorphic Impacts of Levee Breach and Dam Failure" are presented. Experiments of two-dimensional dam-break flows over a sand bed were conducted at Université catholique de Louvain, Belgium. The water level evolution at eight gauging points was measured as well as the final bed topography. Intense scour occurred close to the failed dam, while significant deposition ...

Multi-frequency acoustic backscatter profiles recorded with side-looking acoustic Doppler current profilers are used to monitor the concentration and size of sedimentary particles suspended in fluvial environments. Data at 300, 600, and 1200 kHz are presented from the Isère River in France where the dominant particles in suspension are silt and clay sizes. The contribution of suspended sediment to the through-water attenuation was determined for three high concentration (> 100 mg/L) events and ...

A multi-technique approach is proposed to study sand dynamics in an engineered piedmont river. Only a few studies focused on such systems and innovative methodological protocols still need to be designed to better understand sand transport in piedmont rivers where bedload dynamics has been largely modified with nowadays a residual sand transport on a fixed gravel matrix. The proposed methodology is based on an analysis of bathymetry and turbidity measurements and on modelling, including the development ...

For the evaluation of perceived quality in audio coding, two well-known subjective test methods, both of which are based on Basic Audio Quality (BAQ), are recommended by the International Telecommunication Union. Although a predictor of quality, BAQ is likely to be multidimensional. Listening tests can be used to evaluate other attributes that contribute to impairments created by coding. The goal of this study is to define categories of additional attributes, thereby providing a complement to the ...

La vision habituelle des canaux de transmission de la politique monétaire, telle qu'elle est généralement enseignée à l'aide de modèles standards de type IS/LM, s'en tient au seul canal monétaire. Or, il n'y a aucune raison de se limiter a priori à ce seul arbitrage monnaie/titres pour les tenants du canal du crédit ; un resserrement de la politique monétaire tend alors non seulement à augmenter le taux d'intérêt sur les marchés mais aussi à accroître l'écart entre le taux des crédits et le taux sur ...

Abstract Sediment transport is a key process that affects the morphology and ecological habitat diversity of rivers. As part of a gravel augmentation program to mitigate sediment deficit below a dam, gravel mobility in the Ain River in Eastern France was investigated by tracking of a large amount ( n = 1,063) of PIT‐tagged gravels in the field, conducting a probabilistic approach based on published tracer studies, and performing two‐dimensional (2D) numerical modeling of flow and bedload transport. This ...

Abstract The morphological evolution of the entrances and exits of abandoned river channels governs their hydrological connectivity. The study focusses on flow and sediment dynamics in the exit of a cutoff meander where the downstream entrance is still connected to the main channel, but the upstream entrance is closed. Two similar field and laboratory cases were investigated using innovative velocimetry techniques (acoustic Doppler profiling, image analysis). Laboratory experiments were conducted ...

La libération de foncier issue de la destruction des remparts, l’intégration de nouveaux quartiers populeux, le besoin de renforcer les standards des quartiers bourgeois et, plus tard, la desserte de zones périurbaines ont accru les besoins en eau et insufflé des changements d’échelle techniques. Le passage d’une solution de production traditionnelle à la ...

According to a set of several hundred of French hydrometric stations, the standard uncertainties are of the order of 1% (i.e ± 5 cm) on flood water level, and between 3 to 5% on discharge measurement, with larger values when flow velocity or gradient of water raising are important. More than half of the rating curves ...

This paper introduces an 1D numerical code RubarBE for hydraulic and mobile-bed simulations. The code's ability to reproduce the downstream fining of a gravel–sand mixture in response to bed aggradation is tested against laboratory experiments. Unlike in most numerical models, grain size distribution in each sediment layer is not represented using a multi-class model, but using the median diameter and a sorting coefficient σ. The comparison of numerical results with experimental data shows that ...
