Abstract:

Fluvial sediment transport is a process that has long been important in managing water resources. While we intuitively recognize that increased flow amounts to increased sediment discharge, there is still significant uncertainty in the details. Because sediment transport---and in the context of this dissertation, bed load transport---is a strongly nonlinear process that is usually modeled using empirical or semi-empirical equations, there exists a large amount of uncertainty around model parameters, predictions, and model suitability. The focus of this dissertation is to develop and demonstrat

Abstract:

Accurately calculating bed load transport rate has been a challenge in hydraulic engineering for decades. Bed load transport depends on the interaction between flow and sediment particles. Analyzing the characteristic of sediment particles motion and determining the velocity of sediment particles on a river bed is essential to quantify the transport rate. Therefore, this dissertation reports on the methods and results of a three-phased investigation to analyze the bed-load transport at the grain scale. The first research phase focused on the experimental study of bed-load transport using parti

Abstract:

The effects of particle shape on bedload transport and a wide range of bedload transport rates using both bed subsurface and surface layer based approaches are investigated using fractional transport analysis with a similarity approach. Bedload transport data from a stream containing flat, low density shale particles indicates that the reference transport critical shear stress for the median surface grain size is approximately 2 to 3 times higher than those for more spherical particles. This conclusion indicates a lower susceptibility of disc-like particles to initial entrainment and lower tra

The results showed that there were discernible links between the channel processes and changes which were consistent for all river types. 169 shear stress estimates from velocity profiles with changing discharge showed that Keller's (19

A large number of bed load measuring devices have been developed in order to estimate sediment transport in rivers. In spite of that, the geomorphic and engineering communities do not have a reliable method to estimate bed material load. Available techniques suffer from insufficient temporal and spatial resolution to capture the variability inherent in bed load movement. This work involves the design and construction of an in situ magnetic detection device, which shows promise as a method capable of overcoming these limitations.

The energy system is being transitioned to increase sustainability. This transition has been accelerated by the increased awareness about the adverse effects of the greenhouse gas (GHG) emissions into the atmosphere. The transition includes switching to electricity as the energy carrier in some sectors, e.g., transportation, increasing the contribution of renewable energy sources (RES) to the grid, and digitalizing the grid services. Electric vehicles (EVs) are promoted and subsidized in many countries among the sustainability initiatives. Consequently, the global sales of EVs rapidly increase

Abstract:

The research focus is on the various modeling aspects of flow and sediment transport in water bodies and watersheds. The interaction of flow with a mobile bed involves a complex process in which various turbulent scales characterized by coherent structures cause a chaotic sediment motion. In many rivers and natural waterways secondary flows that are dominating flow struc-tures bring about more complications. In estuaries and open waterbodies thermal stratification and internal mixing control the flow structure besides the flow interaction with the mobile bed. To adequately model these processe

Abstract:

Fluvial sediment transport is controlled by hydraulics, sediment properties and arrangement, and flow history across a range of time scales. This physical complexity has led to ambiguous definition of the reference frame (Lagrangian or Eulerian) in which sediment transport is anal- ysed. A general Eulerian-Lagrangian approach accounts for inertial characteristics of particles in a Lagrangian (particle fixed) frame, and for the hydrodynamics in an independent Eulerian frame. The necessary Eulerian-Lagrangian transformations are simplified under the assumption of an ideal Inertial Measurement Un

Abstract:

Many morphological and environmental problems in rivers are associated with the transport of sediment, in particular with the movement of material along the stream bed. The complex nature of turbulent flow and the variability inherent within granular beds, along with the mutual influence one plays on the other, can only be described using the concepts of probability. It follows that the intermittent motion of bed-load particles can be termed by random variables. The stochasticity of key variables has been recently identified as a source of diffusion, i.e. suggesting that a plume of bed-load gr

This trend is likely to continue with the development of future blended-wing-body and supersonic transport aircraft.

Cette thèse aborde le sujet du monitorage par acoustique passive dans les rivières pour la mesure du transport sédimentaire par charriage. La motivation de la recherche est l’utilisation d’hydrophones déployés dans un cours d’eau pour détecter et mesurer le bruit des sédiments transportés sur le fond de la rivière. La technique est très prometteuse grâce à la facilité de déploiement sur le terrain et aux coûts réduits mais elle est encore déficitaire en méthodologie sur la connaissance du bruit ambiant. Le bruit ambiant est un mélange de sources de bruit parmi lesquelles se trouve le bruit du

Abstract:

Subsurface solute transport is a major mechanism that contributes to the contaminant load in both surface and ground waters. Among these contaminants are plant nutrients that if transported in excessive amounts to surface waters can cause adverse effects on humans and animals, as well as negative impacts on aquatic life. The general objective of this study was to conduct a field evaluation of subsurface solute transport in the capillary fringe (CF) and shallow ground water (SGW) and their contribution to nutrient load in the ditches prior to restoration of a Carolina Bay. Specifically, this st

Abstract:

The purpose of this study is to analyze how estimates of an important geomorphic parameter, effective discharge, are impacted by the choice of bed material load equations and flow duration curves (FDCs). The Yang (1979), Brownlie (1981), and Pagosa equations developed by Rosgen (2006) were compared for predicting bed material load. To calculate the bed material load using the Pagosa equations, the bedload and suspended load are calculated separately and the results are added together. To compare the effectiveness of the equations, measured bed material load data from the USGS Open-File Report
