Temeepattanapongsa, Sathaporn. "Unified Equations for Cutthroat Flumes Derived from a Three-Dimensional Hydraulic Model." DigitalCommons@USU, 2012. https://digitalcommons.usu.edu/etd/1308.
Full textAbstract:
Computational fluid dynamics software was used to simulate the hydraulic behavior of 51 Cutthroat flume (CTF) sizes under various flow conditions, including 24 standard sizes with throat widths (W) from 0.051 to 1.219 m (2 inches to 4 ft), flume scale lengths (L) ranging from 0.457 to 2.743 m (1.5 - 9 ft), constriction ratios (W/L) of 1/9, 2/9, 3/9, and 4/9, and 27 non-standard flumes of intermediate sizes. The validity and accuracy of the simulation results were demonstrated using laboratory data from other studies for 16 of the standard flume sizes and three non-standard sizes. By using the depth-discharge data for 24 standard CTFs obtained from the modeling, a series of "best-fit" calibrations of existing separate free- and submerged-flow rating equations were performed for each of the 24 standard-sized CTFs. A new unified rating equation for free- and submerged-flow conditions for the standard CTF sizes was proposed by comparing a set of empirical equations. The performance of the unified rating equation was also analyzed in order to determine the technical desirability of the equations as substitutes for the existing separate free- and submerged-flow rating equations. For the free-flow rating, the discharge parameters in the traditional equation are generalized to be applicable to any of the CTF sizes with flume lengths ranging from 0.457 to 2.743 m (1.5 - 9 ft), and the constriction ratio ranging from 1/9 to 4/9. This allows the application of CTFs with greater accuracy than the previously available equation. With the new generic-fit equations for the free-flow rating parameters, the discharge error is 4% from the standard discharge, with an average error of 2.2% for full-scale discharge. The generic unified rating equations proposed herein are also applicable to any of the CTF sizes, varying among the 24 standard sizes with flume lengths ranging from 0.457 to 2.743 m (1.5 - 9 ft) and the constriction ratio ranging from 1/9 to 4/9. With the generic-fit equations for the calibration parameters as derived herein, the discharge error is 6 - 8% compared to the standard discharge, and 2 - 3% for full-scale discharge.

Wenn über 10 Jahre nach der sogenannten „Wende“ in den Fluren einer ostdeutschen Universität die Polizei eine unangemeldete Demonstration auflösen muß, bei der nicht nur Transparente mit „Der Kiez gehört uns!!“ und „Kein Verkauf an Frankfurter Immobilienhaie“ getragen werden, sondern auch Hand gegen die RepräsentantInnen der Stadt und einer Immobilienfirma nicht mehr auszuschließen sind, dann kann man sich wohl sicher sein, daß es sich nur um ein Spiel handelt. Genauer gesagt um ein Planspiel: Die beschriebene Szene stammt aus dem ersten Probedurchlauf eines Planspiels zur Sozialplanung in ostdeutschen Städten, das im Rahmen der Lehrforschung an der Professur Regionalforschung und Sozialplanung der TU Chemnitz gemeinsam mit StudentInnen entwickelt wurde .
Ziel dieser Entwicklung war die Schaffung eines methodischen Hilfsmittels, mit dem das Agieren in dem konfliktreichen und komplexen Praxisfeld der Sozialplanung „geübt“ werden kann. Als Zielgruppe waren dabei einerseits StudentInnen in entsprechenden Disziplinen als zukünftige AkteurInnen solcher Prozesse im Blickfeld, gleichzeitig aber auch und gerade PraktikerInnen, die bereits im Feld der Sozialplanung tätig sind. Gerade ihnen sollte das Planspiel eine Möglichkeit bieten, die verschiedenen Handlungsmöglichkeiten in der Sozialplanung auszutesten, ohne dass daraus sofort Konsequenzen für den eigenen Praxisalltag erwachsen. Hintergrund der Spielentwicklung war dabei nicht zuletzt die Praxiserfahrungen der beiden AutorInnen, die in Chemnitzer Stadtteilen aktiv in der Sozialplanung tätig waren, unter anderem im Rahmen der EU-Gemeinschaftsinitiative URBAN und des Bund-Länder-Programms „Stadteile mit besonderem Erneuerungsbedarf – die soziale Stadt“.

Full textAbstract:
A Sediment-Resistant flume has been tested and analyzed in the laboratory and field to measure flow rate with high sediment concentration for natural and irrigation streams. This flume is basically an improvement of the well studied long-throat flume which has an additional chute proposed by J. A. Replogle. The chute, where a new gauging station is located at the half-way point of its length equal to two times the throat length, worked satisfactory for a chute slope of 3%. For clear-water flow the chute showed a supercritical and curvilinear flow having a hydrostatic pressure consistently located at the halfway of the chute. For sediment-laden flow with a concentration of 3% by weight of clear mortar sand, behavior was similar to the clear-water. Sediment deposits filled the approach channel of the flume and plugged the intake pipe of the supercritical gauging station causing it to fail. This failure was compensated for by the use of the new supercritical additional gauging station located in the chute, which remains clean and continues to measure the flow-rate. Hydraulic behavior of the stage-discharge curves for the sediment-laden flow flume was similar to the clear-water flow after the approach channel was filled. Prior to filling an inconsistent condition existed caused by the sediment movements in the approach channel. It was shown that this flume might be used in the field with errors of 5% or less. In addition, a computer program was developed to compute the stage-discharge curve using the dynamic equation of gradually varied flow, which may be used to compute the stage-discharge curve in new flumes. Further laboratory and field research is to be expected to compare these results with future data to improve reliably.

Full textAbstract:
Ökologie und Hochwasserschutz müssen keine Widersprüche sein. Mahner hat es immer gegeben, die daran erinnerten, dass die Flüsse ihren Raum, also ausreichend natürliche Überschwemmungsflächen brauchen. Doch wie ernst haben Verwaltung und Regierende diese Erkenntnisse seit dem sogenannten Jahrhunderthochwasser 2002 genommen? Wo haben sie die Schwerpunkte gesetzt, wofür Steuergelder ausgegeben und wofür nicht? Seit 20 Jahren werden immense Summen für die Wasserstraße Elbe und für die Häfen am Fluss ausgegeben. Die Elbe sollte mehr Verkehr aufnehmen. Welchen Nutzen haben diese Investitionen? Sind die gesteckten Ziele überhaupt erreicht worden? Seit zehn Jahren werden Hunderte Mio. Euro für den Deichbau ausgegeben, damit es nicht wieder wie 2002 zu Deichbrüchen und ungewollten Überflutungen kommt. Aber das Wasser muss ja irgendwohin, wenn es in Massen kommt! Doch nur noch auf 16 Prozent der einstigen Überschwemmungsauen der Elbe kann sich der Fluss im Hochwasserfall ausbreiten. Und so lief das Wasser im Juni 2013 erneut in zahlreiche Wohnzimmer. Als Lehre aus dem Hochwasser 2002 wollte Sachsens Staatsregierung den Flüssen mehr Raum geben. 7.500 Hektar zusätzliche Überflutungsflächen waren damals im Gespräch, insgesamt 49 Maßnahmen. Und was wurde davon umgesetzt? Ganze 1,5 Prozent! Schlimmer hätte die Bilanz des politischen Versagens nicht ausfallen können. Die Folgen des vorwiegend technischen Aufrüstens der Deiche müssen nun andere ausbaden – nämlich die Unterlieger. Sankt Florian lässt grüßen! Sie werden mit noch höheren und schnelleren Fluten bestraft. Eine intelligente, nachhaltige und solidarische Flusspolitik sieht anders aus. Vorschläge, wie künftig anders gehandelt werden muss, bringt die Fraktion BÜNDNIS 90/DIE GRÜNEN im Sächsischen Landtag hiermit in die öffentliche Debatte ein.:Vorwort 4

Full textAbstract:
Sixteeen sets of original laboratory data collected by many investigators for various Cutthroat flume sizes are thoroughly reviewed and organized. Best-fit discharge parameters are obtained by performing the free-flow analysis and the submerged-flow analysis. Then, the transition submergence can be calculated. Afterwards, the unified free-flow and submerged-flow discharge parameter s are developed for each flume size in order to generalize the calibrations for Cutthroat flumes. This is a very tedious process requiring a trial-and-error approach. Finally, comparisons are made of the measured laboratory discharges with the predicted discharges for both free flow and submerged flow using both the best-fit and the unified discharge parameters.
The results proved quite good as measured by the standard deviation for each flume size. In most cases, the average standard deviation using the unified discharge parameters was only slightly greater than when using the best-fit discharge parameters. However, there is a significant difference in the accuracy of free-flow measurements compared with submerged-flow measurements. Using the unified discharge parameters, the mean standard deviation for all of the flumes was 2.1 percent for free flow and 6.5 percent for submerged flow.

Full textAbstract:
As part of a continued research project for the Utah Water Research Laboratory and the State of Utah, a study of flow measurement devices is being conducted throughout the state. Initially the project included only measurement devices associated with high-risk dams, but has since been broadened to any measurement structure of interest for water users in the state. The physical dimensions, relative elevations, and flow accuracy were documented for each included device.
After visiting sixteen sites, it was found that fourteen of the measuring devices had incorrect geometries. Of these fourteen, thirteen of them were originally Parshall flumes. A large percentage of Parshall flumes with geometry inaccuracies was also found from previous data collected for this project. One reoccurring issue was that the flumes had not been well maintained and had damage to the walls or floor. Some of these Parshall flumes did not have a diverging downstream section and are referred to as Montana flumes. In these cases, a standard Parshall rating curve was used to determine flow where it did not apply. Some of the flumes that were tested operated regularly under submerged conditions, and no adjustments were made for submergence.
The objective of this research is to determine if Montana flumes (Parshall flumes without a diverging section) operate similarly to fully constructed Parshall flumes under both free-flow and submerged conditions. Laboratory tests were performed in the Utah Water Research Laboratory to determine corrections for submergence. Flow 3D, a computational fluid dynamics (CFD) software program, was also used to develop corrections for a submerged Montana flume. The laboratory results were compared to the computational fluid dynamics results. By using Flow 3D, a reliable numerical process was developed to determine the flow rate in a submerged Montana flume in an effort to expand the results to other seized flumes.

Thesis (S.M.)--Massachusetts Institute of Technology, Dept. of Earth, Atmospheric, and Planetary Sciences, 2007.<br>Includes bibliographical references (p. 49-50).<br>Laboratory flume experiments are used to examine the role of suspended sediment abrasion in bedrock channel erosion. A range of topographies was used, from a planar bed to a sinuous and scalloped inner channel. Experiments were run separately with bedload (used to form topography) and suspended load at a variety of water flows and sediment fluxes. Sediment samples were collected to determine mass flux and concentration profiles. Erosion was measured between each timestep and erosion rate determined for a variety of conditions. Rouse, Froude, and Stokes numbers were calculated from measured data for various timesteps to determine mode of sediment transport and flow characteristics. Flow was supercritical, and sediment was in suspension. Erosion patterns around imposed topography perturbations (a rock protrusion and a drilled pothole) were briefly examined. A hydraulic jump was used in one timestep to see the effect of the transition from supercritical to subcritical flow. Suspended sediment causes erosion in all bed morphologies. The amount and pattern of erosion are coupled to topography, but are not constrained by it to the same degree as bedload. As in the case of bedload, suspended sediment erosion is strongly coupled to sediment flux.<br>by Katrina Muir Cornell.<br>S.M.

Full textAbstract:
Lors d’une opération de forage, un certain nombre d’événements imprévus par rapport à l’écoulement du fluide de forage dans le puits, peuvent se produire assez rapidement. Des exemples de tels événements sont les afflux de pétrole ("kick") ainsi que les pertes de boue dans la formation. Un "kick" qui augmente en intensité peut entraîner, par ce que l’on nomme, un "blowout" (par exemple l’incident Deepwater Horizon en 2010). Les pertes et les gains sont habituellement détectés en contrôlant l’équilibre de la boue de forage dans le puits, en particulier en contrôlant le débit sortant du puits et en le comparant au débit entrant induit par les pompes. La plupart des méthodes de surveillance, de l’écoulement du puits en cours de forage, est d’utiliser un simple "paddle" (capteur qui mesure la hauteur du fluide de forage avec l’inclinaison d’une pagaie) dans la ligne d’écoulement de retour, ou d’utiliser un débitmètre de Coriolis (débitmètre connu pour sa précision, mais coûteux et nécessite une installation complexe en ajoutant un "by-pass"). Il y a un besoin évident d’un nouveau débitmètre précis, mais facile à installer et peu coûteux. Le canal Venturi a été utilisé comme débitmètre pendant des années dans l’industrie des eaux. Il apparaît comme une solution peu chère mais précise pour mesurer des débits importants. Beaucoup de personnes ont travaillé sur cette solution pour améliorer sa précision et élargir son champ d’application. Ils ont développé des modèles, sur la base d’un processus d’étalonnage, permettant de relier la hauteur en amont au débit. Cela signifie que les modèles actuels, comme ISO NORM 4359 [1], peuvent être uniquement utilisés pour l’écoulement d’eau et pour une géométrie bien spécifique. Comme nous le savons, les boues ont des comportement non- Newtonien, et donc ces modèles établis ne peuvent pas être utilisés avec ce type de fluides. Pour notre application, la forme trapézoïdale apparaît comme un bon compromis entre la précision et la portée des mesures de débit. Ainsi, nous avons développé un modèle capable de calculer le débit en prenant en compte les propriétés du fluide ainsi que les paramètres géométriques du canal. Ce modèle a été simplifié sous forme 1D en utilisant la théorie des eaux peux profondes, et a été complété par un modèle de friction tenant en compte de la variation des propriétés des fluides et de la géométrie du canal. Ce modèle a été validé par une série d’expériences avec les deux types de fluides: Newtonien et non-Newtonien, où nous avons mesuré le débit et la hauteur de l’écoulement à différents endroits le long du canal Venturi. Nous avons également réalisé des simulations 3D, en simulant des écoulements Newtoniens et non- Newtonien le long du canal. Pour généraliser cette étude, cette démarche a été étendue à une autre forme de Venturi plus adapté à un certain design de plate-forme pétrolière. Les corrélations et les modèles développés et validés expérimentalement au cours de cette étude peuvent être utilisés pour étendre l’utilisation des canaux Venturi à tous les fluides Newtonien mais aussi non-Newtonien. Il est maintenant l’occasion pour les industries de proposer une solution, peu chère mais précise pour mesurer les débits dans des canaux ouverts et pour tous types de fluides<br>During a drilling operation, a certain number of unexpected events, related to the flow of drilling fluid in the well, may happen rather quickly. Examples of such events are formation fluid influx (kick) and mud loss to the formation. An uncontrolled kick that increases in intensity may result in what is known as a blowout (e.g. the Deepwater Horizon incident in 2010). Influxes and kicks are traditionally detected by monitoring the drilling mud balance in the well, in particular, by monitoring the flow out the well and comparing it to the incoming flow induced by the pumps. Most methods of monitoring the flow out of the well while drilling consists in using a simple paddle (sensor that measures the height of drilling fluid with the inclination of a paddle) in the return flow line, or in using a Coriolis flow meter (flow meter known for its accuracy but expensive and requires a complex installation by adding a bypass). There is a clear need of a new accurate flow meter, but easy to install and inexpensive. The Venturi flume has been used as flow meter for years in water industry. It appears as a cheap but accurate solution to measure large flow rates. Many people have worked on this solution to improve its accuracy and to expand its scope. They have developed models, based on a calibration process, to relate the upstream height to the flow rate. This means that current models, as ISO NORM 4359 [1], can be used only for water flow and specific geometry. As known, muds have non-Newtonian behavior and water models cannot be used with this kind of fluids. For our application, trapezoidal shape appears as a good compromise between accuracy and range of flow rate measurements. Thus, we built a model able to compute the flow rate with taking into account fluid properties and geometrical parameters. This model is simplified in 1D form by using the Shallow Water theory, and completed by a friction model taking into account the variation of fluid properties and geometry along the open channel. It have been validated by series of experiments with both Newtonian and non-Newtonian fluids, where we measured the flow rate and heights of the flow at different locations along the trapezoidal Venturi flume. It have been also completed by 3D CFD which has been simulated both Newtonian and non-Newtonian flows along the flume. To generalized this study, the work was extended to another shape of Venturi more suited to some rig design. The correlations and models developed and experimentally validated during this research can be used to extend the use of Venturi flume flow meters for any fluids : Newtonian and non- Newtonian. It is an opportunity for industries to propose a cheap but accurate solution to measure flow rates in open channels with any kind of fluids

Full textAbstract:
Test sections in laboratory studies should be fully developed and uniform if they are to be generalized. The objective of this study is to develop a model for predicting the uniform flow development length (Lunif) in a rough laboratory flume as a function of hydraulic parameters and bed particle roughness height (ks). Using an ADV time-averaged point velocity was measured in developing and fully developed turbulent subcritical rough open-channel flows. A series of laboratory tests were carried out in a 6.1-m-long and 0.46-m-wide rectangular channel. Tests were conducted with fine gravel (d50 = 5.8 mm, ks = 3.1d90 = 0.026 m), medium gravel (d50 = 14 mm, ks = 0.068 m), and with fine /medium gravel (d50 = 11 mm, ks = 0.04 m). For each test, longitudinal point velocity measurements were made along the center of the channel at five elevations, and at thirteen longitudinal stations. The study concluded that for flow to be uniform, the flow depth and mean cross-sectional velocity must be constant. In addition, root mean square of the fluctuating component of the velocity, RMS(u'), which is the measure of the turbulence intensity, should be uniform in order for a flow to consider uniform. Thus, RMS(u') is one of the indicative measures for determining the location where the developing flow is fully developed and uniform. The results showed that increasing the bed roughness height decreases the uniform flow development length. Using the dimensional and statistical analyses Lunif was estimated as a linear function of Reynold's particle number and Froude number.

Full textAbstract:
In this thesis, the interaction between flow and sediment in alluvial channels is studied from an empirical approach, for conditions close or pertaining to supercritical flow, and for four types of sediment: sand, gravel and two mixtures with sand and gravel in a relative proportion of 70-30 and 55-45, respectively. The objective is to obtain by means of laboratory experiments a data set with the characteristics of flow, sediment transport, bed configurations and sediment sorting patterns in sediment mixtures, for different conditions within upper- and transitional-regimes. From a practical perspective, the aim of this work is to reproduce similar conditions to those likely to occur in torrential ephemeral streams, common in the Mediterranean coast and known in Spain as ¿ramblas¿.
The experimental work consisted in searching for mobile-bed equilibrium states, for different water discharges and sediment-feed rates. The definitive data set comprises 22 runs, with durations up to 12 hours. Sediment-feed rates were constant during each run, and they were even higher than 1 kg/s. Dominant bed configurations included transitional bedforms and trains of antidunes, coexisting with alternate bars. Antidunes were mostly three-dimensional rather than two-dimensional, and in contrast to the most referred antidunes in literature, the antidunes herein reported moved in the downstream direction and were stable most of the time. Short-crested stationary waves on the water surface accompanied the antidunes.
Characterization of the experimental bedforms allowed identifying the range of Froude numbers in which transitional regime prevails for the studied sediment; also, this characterization allowed assessing the performance of theoretical and empirical diagrams for bedform stability phases. It is here demonstrated that for very coarse sand, fine gravel and mixtures of these two materials, plane bed does not occur in the transition from lower- to upper-regime, and if it would occur, it would be restricted to a very narrow range of Froude numbers. Regarding flow resistance related to bedforms in upper-regime, it has been here probed that for similar geometrical conditions, downstream-migrating antidunes produce less flow resistance than dunes, and more flow resistance than upstream-migrating antidunes.
An important concern in this work has been to investigate the effect of the relative sand content of sediment in bedforms, flow resistance and sediment transport. It is here demonstrated that bedforms in sand beds can be higher and they can produce much more drag than bedforms in gravel and sand-gravel mixtures. Regarding sediment transport, it is here shown that for the high sediment-feed rates tested in the experiments, certain ranges of sand content would affect sediment mobility. Besides sand content, it is shown that the ratio between sand and gravel grain sizes would also be relevant in the mobility of sediment in comparison to well-sorted material. A conceptual model is suggested for computation of sediment incipient motion, which model is based on the variation of bed porosity with sand content and on the relative size between particles.
Some supplementary themes considered in this work include the study of the required conditions for the formation of three-dimensional stationary waves over antidunes; the hydraulic analysis of flow over antidunes and the morphological consequences of such a flow for the three likely regimes of antidune direction of movement; sediment sorting patterns according to sand content, especially bed surface patches of homogeneous sediment; and finally, the analysis of the process by which fine sediment penetrates into a bed composed of particles of diverse sizes.<br>En esta tesis se estudia de manera empírica la interacción entre el flujo y el sedimento en

para diferentes condiciones dentro de los regímenes superior y de transición. De manera
práctica, la intención de este trabajo es reproducir condiciones comparables a las que
pueden ocurrir en ríos efímeros de carácter torrencial, comunes en la costa Mediterránea y
conocidos en España como ramblas.
El trabajo experimental consistió en la búsqueda de condiciones de equilibrio
dinámico en lecho móvil, para diferentes caudales líquidos y tasas de alimentación de
sedimento. 22 ensayos, con duraciones de hasta 12 horas, conformaron el grupo de datos
definitivo. Las tasas de alimentación fueron constantes durante cada ensayo, y alcanzaron
valores de incluso más de 1 kg/s. Las configuraciones de fondo dominantes incluyeron
formas de fondo de transición y trenes de antidunas, en coexistencia con barras alternadas.
Predominaron las antidunas tridimensionales sobre las bidimensionales y, a diferencia de las
antidunas más referidas en la literatura, las aquí descritas migraban hacia aguas abajo y eran
bastante estables. En la superficie del agua acompañaban a las antidunas ondas
estacionarias de cresta corta.
La caracterización de las formas de fondo experimentales permitió identificar el
intervalo de números de Froude en el cual prevalece el régimen de transición en el
sedimento estudiado y también evaluar diagramas teóricos y empíricos para las regiones de
estabilidad de formas de fondo. Se demuestra que en arena muy gruesa, grava fina y
mezclas de estos dos materiales, en la transición de régimen inferior a superior no ocurre el
fondo plano, y si así fuese, estaría restringido a un intervalo muy estrecho de números de
Froude. En cuanto a la resistencia al flujo producida por las formas de fondo en régimen
superior, se ha probado que para condiciones geométricas similares las antidunas que
migran hacia aguas abajo producen menos resistencia al flujo que las dunas y más
resistencia que las antidunas que migran hacia aguas arriba.
De particular interés ha sido reconocer el efecto en las formas de fondo, la
resistencia al flujo y el transporte de sedimento, del contenido relativo de arena en el
sedimento. Se muestra que las formas de fondo desarrolladas en lechos compuestos sólo de
arena pueden ser de mayor magnitud y producir mucha mayor resistencia de forma que las
formas de fondo en grava y mezclas de grava-arena. En cuanto al transporte de sedimento,
se muestra que para las altas tasas de transporte probadas ciertos intervalos de contenido de
arena afectan la movilidad del sedimento. Además de la proporción de arena en la mezcla,
el grado de afectación en la movilidad estaría relacionado con la relación entre tamaños de
la arena y la grava. Se propone un modelo conceptual para el cálculo del inicio de
movimiento de las partículas del fondo, el cual considera la variación de la porosidad en el
lecho con el contenido de arena y la relación de tamaños de las partículas.

Full textAbstract:
Almost all sediment transport equations incorporate the Shields parameter, which is a ratio of the total boundary shear stress as a driving force and the particle weight as a resisting force. Shields (1936) equated particle resistance to entrainment with particle weight, which is proportional to particle diameter, or bed texture. The present work analyses the particle resistance term in the Shields parameter.
As the bed material adjusts to a given flow condition, bed stability increases. The arrangement of particles into more stable configurations is here termed geometric structure, and includes the formation of pebble clusters, and imbrication. After an initial surface coarsening, here termed textural structure, particle resistance to movement is a function primarily of geometric structure. The Shields number for entrainment is thus a measure of particle resistance due to both types of bed structure rather than the conventional notion of particle resistance due to particle weight.
The response of a mobile bed surface composed of < 8 mm diameter gravels to flowing water was explored in a 6 meter by 0.5 meter flume using four different slopes and various water depths. Corrected bed shear stresses varied between 0.05 and 2.79 Pa. Step increases in discharge with a constant slope caused the bed surface to develop a structure which was more stable at the end of a run than at the beginning. Under these conditions, the Shields number for incipient motion was found to vary between 0.001 and 0.066. This variability can be explained by the degree of geometric structure present. Previous studies, including Shields' work (1936), have implicitly included the effects of geometric structure on incipient motion.
Surface coarsening develops with very low flows, but subsequent coarsening in higher flows is minor, with less than 5% increase in median diameter following a 50% increase in bed shear stress. Calculations of Manning's n based on depth, slope, and velocity measurements show an increase in flow resistance as structure develops. The development of a coarse surface layer appears to be limited by flow characteristics near the bed which are in turn modified by the development of structure. Measurements of the area occupied by the largest stones show that they do not cover more than 14% of the surface during maximum coarsening. Froude scaling of the flume data indicates that the time necessary for development of maximum strength is on the order of a month for natural rivers under steady flow conditions. This suggests that gravel river beds are rarely in equilibrium with natural flow conditions.<br>Arts, Faculty of<br>Geography, Department of<br>Graduate

Full textAbstract:
Although deflectors are commonly used in fish habitat rehabilitation projects to create and/or maintain pools, there is a lack of understanding of the complex flow field and scour patterns around these structures. The objective of this research is to quantify the 3D flow dynamics and the bed morphology around various designs of flow deflectors in a laboratory flume over a plain and mobile bed. 3D velocity measurements were taken with an acoustic Doppler velocimeter. After comparing different methods of bed shear stress estimates, it was determined that the turbulent kinetic energy approach was best at capturing the shear stress amplification near the deflectors. Deflectors oriented perpendicular to the flow create the most important disturbance of the flow field, the greatest increase in turbulence intensity and the largest scour hole, followed by upstreamoriented deflectors (135°) and downstream-oriented ones (45°). 90° deflectors would therefore potentially provide the greatest benefit for fish habitat rehabilitation.

Full textAbstract:
Fluvial suspended sediment (FSS) is a measured physical component of
hydrologic and environmental watershed studies. A variety of tools and strategies are
employed to collect a FSS sample that is representative of the source water FSS. The
discrete point-in-time automatic fixed speed pump sampler (DPS) is a commonly used
tool in FSS studies. During May-October 2006, two prototype FSS samplers, a time
integrated passive sampler (TIPS) and a continuous flow proportional variable speed
pump sampler (CPS), were evaluated using an instream flume and a DPS sampler, placed
in a small, low energy, second order stream in the Southern Interior of British Columbia,
Canada. The time integrated passive sampler consisted of a passive instream sampler,
and collected FSS continuously over a 24-hour period from a point in the stream
cross-section. The CPS consisted of a combined instream suction pipe, pressure
differentially controlled variable speed peristaltic pump, removable inclined pipe
expansion, and filter bed system. The CPS pumped and filtered water for FSS
continuously over a 24-hour period from a point in the stream cross-section. The instream
flume consisted of an immersed 1 m diameter by 5 m long half pipe section on adjustable
legs.
Results indicated that all three samplers were correlated in the assessment of FSS
silt/clay (mineral particle size fractions < 53 μm), sand (mineral particle size fractions
> 53 μm), and organic matter based on weight, concentration, and percent proportions.
Regression results demonstrated that there was disagreement between the DPS and the
other two samplers for the assessment of organic fractions. The CPS- and TIPS-measured
blend of percent organic and percent mineral fractions were in agreement, particularly if
the TIPS measured percent sand was less than 35%. The TIPS collected FSS variables
were most responsive to changes in flume flow velocity (log-log relationship),
particularly the measurement of FSS total weight. The TIPS weight variables were
predictors of flume FSS load values when calibrated to CPS or DPS load values.
The study of the TIPS operational characteristics revealed that the inlet velocity
was less than the ambient flume velocity of 400 mm ⁻¹ by a factor of 3.9. The proportion
of inlet FSS retained in the TIPS body was determined by studying the ratio of expelled
to retained FSS proportions (E:R). The E:R ratio was stable at 1:1 for flume velocities
between 300 mm ⁻¹ and 400 mm s⁻¹. The E:R ratio varied predictably (linearly)
according to the flume velocity, but less predictably according to changing proportions of
organic matter, mineral particle size < 53 μm, and mineral particle size> 53 μm.
The TIPS and CPS were capable of collecting enough FSS to assess a mineral
particle size < 53 μm and> 53 μm. DPS assessment was restricted by the collected
sample size to the assessment of organic matter and total mineral fractions only. The
DPS was capable of partitioning the 24-hour hydrograph into 2-hour segments, whereas
the CPS and TIPS collected a time integrated composite sample over the 24-hour period.
The DPS pump speed was fixed, whereas the CPS pump speed was variable, according to
the pressure differential readings on a venturi at the TIPS sampler outlet that responded to
flume flow velocity. The instream flume provided a stable 24-hour sediment supply,
linearized flow and isolated the FSS supply from streambed sediments. The flume was
also a convenient, adjustable working platform above the watercourse.
The CPS and TIPS prototypes represent successful initial steps toward designing
an alternative sampling device to the automatic pump sampler.

Dissegna, Camilla. "Experimental analysis of the MoonWEC floating model in a wave flume." Master's thesis, Alma Mater Studiorum - Università di Bologna, 2020.
Find full textAbstract:
This document aims to show the experiments conducted in order to validate the MoonWEC’s theoretical floating model, together with the description of relative results. The MoonWEC is a wave energy converter prototype designed as a point absorber working as an oscillating body in heave. It’s composed of a cylindrical floating body with a cylindrical hollow inside it which works as a moonpool when filled by water, and from which the device also takes its name. The device exploits the relative motion between the floater and the moonpool for energy conversion and, in order to maximize said relative motion, the two bodies have to resonate synchronously but with opposite phases.
A scale model of the MoonWEC was realized and used for the experiments that were carried out at the LIDR (Hydraulic laboratory of the Alma Mater Studiorum Università di Bologna) with the purpose of studying the floater’s motion and response in terms of degrees of freedom when subject to the action of different wave conditions. The model was placed inside a wave flume equipped with a wave generator, its motion when subject to the action of the different test waves was recorded using a GoPro video camera, while a set of wave gauges recorded the water level variation and a pulsed ultrasound velocimetry device, the DOP2000, sampled the water level and velocity profiles inside the moonpool.
The data collected from these three different instruments were analyzed and compared through MATLAB. The test waves parameters were obtained from the zero-crossing analysis of the gauges data; the surge, heave and pitch responses of the floater could be obtained through a video analysis of the MoonWEC’s motion; and the DOP analysis supplied the moonpool’s water level oscillations. All the signals were then compared with each other both in the time and frequency domains and the response amplitude operator (RAO) was evaluated for each degree of freedom of the floater.

Full textAbstract:
The Utah Water Research Laboratory, in conjunction with the State of Utah, initiated a study to determine the accuracy of a wide variety of flow measurement devices in Utah. The project selected 70 sites with flow measurement devices throughout the state. During the assessment each device had its physical condition and flow measurement accuracy documented.
Although a wide variety of flow measurement devices were tested, the majority were Parshall flumes. Many of the assessed Parshall flumes were not measuring flow to the specified ±5 percent design accuracy. Problems in flow measurement were due to issues with the staff gauge location and incorrect entrance geometry. Laboratory tests were conducted at the Utah Water Research Laboratory in an attempt to provide accurate flow measurement from flumes with these issues. The tests simulated incorrect locations for measuring upstream head with different entrance geometries on a 2-ft-wide Parshall flume.
The flume was tested with three different entrance wingwall configurations, eighteen stilling wells, and two point gauges, allowing water surface profiles to be collected throughout the flume. Corrections for incorrect head measurement locations and entrance geometries were created.
The objective of this thesis is to provide water users and regulators with the information necessary to help improve open-channel flow measurement accuracies. An overview of design accuracies and flow measurement devices is given. In addition, a method to correct for incorrect head readings in Parshall flumes, a widely used flow measurement device in Utah, is presented. It is expected that this information will help water users and regulators monitor their water with the understanding necessary to ensure that water is more accurately measured.

Peloutier, Vincent. "Flume study of the deposition of fine sediment into river gravel." Thesis, University of Glasgow, 1998. http://theses.gla.ac.uk/8485/.
Full textAbstract:
Increased land erosion and drainage, combined with larger impoundments for water consumption needs, result in increased levels of sediments infiltrating into gravel river beds. This can cause a threat to the ecology of rivers and to fish populations. However, the mechanisms by which transported fine sediments deposit, i.e. pass through the surface layer of gravel before infiltrating into the bed pores, are poorly researched. Several investigators have highlighted the needs for further explorations in that field, as it also has direct implications in phenomena such as flood hydraulics sediment transport, armouring and downstream fining. Previous studies have indicated that deposition rates are proportional to sediment concentrations and fall velocities in still water. A preliminary series of experiments was conducted in an 8m-long flume to compare deposition rates of sand through single layers of gravel to transport rates measured 25mm above the bed surface. It was found that the deposition rates Δ are proportional to the near-bed concentration of fine particles Cb. The constant of proportionality has the dimension of a velocity, and represents an average fall velocity through the bed surface layer, or deposition velocity wd. The ratio between the deposition velocity wd and the fall velocity in still water wd*, referred to as the dimensionless deposition velocity Wd*, gives an indication of the effects of the gravel bed surface on the settling behaviour of the sediment particles. Following the preliminary series of experiments, the main series of experiments was aimed at measuring deposition velocities in different hydraulic and sediment conditions to study the physical mechanisms controlling the deposition process. It was found that the deposition velocity generally increases with grain size, but tends to stabilise in the upper size range (i.e. particles transported by saltation). Deposition velocities tend to decrease as bed shear stress and turbulence level increase, particularly in the case of medium-size sand (~300-350µm). Gravel size does not appear to have a significant influence on the deposition velocity of particles coarser than ~200µm. The deposition velocity results of experiments using medium-size sand were, in general, larger than the fall velocity Ws for particles finer than ~200µm in diameter, indicating a phenomenon of enhanced deposition. This phenomenon has already been observed in previous studies (e.g. Jobson and Sayre, 1970). It was not detected in experiments using very fine sand, but the deposition velocity results in this case followed similar variations with grain size to that observed with medium sand. The experimental results suggested a distinction between three ranges of fine sediment: (1) the Stokes' range includes very fine particles, the diffusion coefficient of which is nearly equal to that of the fluid. The depositional behaviour of these particles is directly influenced by the structure of near-bed turbulence. A bursting-based analysis showed that the so-called deposition parameter wd+ = wd u* / (g d) is in this case related to near-bed turbulence and bed roughness parameters, but not to the grain size; (2) the intermediate range, which is influenced by both turbulence and gravity. A dimensional analysis indicated that, under these circumstances, Wd+ increases with grain size; and (3) the upper range, which corresponds to the range of particles transported by saltation. Deposition is, in this case, mainly influenced by the landing angle of the fine particles and the bed surface topography. The experiments also indicated that the deposition process is influenced by turbulence damping, a phenomenon which consists in the reduction of the eddy diffusivity of the fluid by increasing sediment transport concentration and grain size. This phenomenon can be described using van Rijn's φ coefficient. It was observed that the deposition velocity wd tends to increase with increasing turbulence damping. The experimental results were applied to model downstream sorting of fine particles in gravel-bed rivers in 2-D uniform flow conditions. Methods of computation and examples of applications are described.

Full textAbstract:
I detta arbete undersöker jag processen kring att kombinera modern popmusik med sound healing och ASMR. Under arbetet har jag sammanställt ofta förekommande element inom ASMR och sound healing och därefter producerat poplåtar där jag lagt till dessa element. Låtarna skapades utifrån en struktur av modern pop där fokus låg på vocals, production och ”finishing touches”. Arbetet resulterade i tre låtar som enligt mig lyckades kombinera de två världarna. Många artister har på liknande sätt experimenterat med att sammanföra dessa genrer, bland de mest framgångsrika är Björk och Billie Eilish, som båda på sitt eget sätt har varit framträdande i att skapa ett eget och unikt sound genom att använda ljud som går att hitta i ASMR i sin popmusik. Utmaningen i att kombinera genrerna låg i att deras progression och uppbyggnad i stor utsträckning skiljer sig åt samt vilket syfte de är de tänka att konsumeras för. Jag insåg dock under arbetets gång att genrernas olikheter är just det som gör att de kompatibla. Konstnärlighet och teknik gick hand i hand då en stor del av produktionen låg i att hitta eller skapa rätt ljud, samt att producera ett binaural sound. För detta laborerade jag med olika inspelnings -och mixtekniker, såsom att spela in i binaural stereo och prova olika upptagning på mikrofoner, samt att mixa i surround och binaural.<br>In this work I examine from a musicproducers point of view how to combine modern popmusic with sound healing and ASMR. I explored many aspects of the different styles of music and sounds as well as wrote and produced songs that strived to find a balance between the three genres. Atristic choices and the techinal aspect of producing became main focus as I elaborated with different recording and mixing techniques, such as binaural and surround. This empirically based studies resulted in this work as well as compositions created with the intention of musically merging modern pop with traditional sounds.
