Streszczenie:

Turbidity currents are one of the primary means of transport of sediment in the ocean. They are fast-moving, destructive fluid flows which are able to entrain sediment from the seabed and accelerate downslope in a process known as `ignition'. In this thesis, we investigate one particular model for turbidity currents; the `Parker model' of Parker, Pantin and Fukushima (1986), which models the current as a continuous sediment stream and consists of four equations for the depth, velocity, sediment concentration and turbulent kinetic energy of the flow. We propose two reduced forms of the model; a

Streszczenie:

Turbidity currents are large-scale natural phenomena that consist of suspended sed- iment travelling over an impermeable underlying boundary. We employ a shallow- layer approach to model their dynamics, taking advantage of the fact that their streamwise length is much larger than their vertical height. We frequently consider flows initiated by the instantaneous release of a finite volume of stationary material, known as a 'dam break' configuration. New complete analytical solutions of dam-break flows into a layer of quiescent fluid, or 'tailwater', are found. The tailwater's presence introduce

Correntes de densidade são fluxos gravitacionais gerados pela diferença de densidade entre dois fluidos. Correntes de turbidez fazem parte de uma sub-classificação das correntes de densidade, na qual o fluido mais denso tem, na sua composição, partículas em suspensão. Muitos trabalhos numéricos já estudaram a dinâmica das correntes de turbidez, mas, nenhum dos encontrados aplicou mudanças de relevo concomitantes com a simulação, causadas pela sedimentação das próprias partículas da corrente e nem alterou o relevo após a passagem de cada evento em um domínio tridimensional.

Deposits of turbidity currents - turbidites - commonly exhibit upward-fining grainsize profiles, reflecting deposition from flows with simple rapidly-waxing then progressively-waning velocity structures. However, turbidites with patterns of multiple cycles of inverse-to-normal grading are not uncommon. Such deposits are interpreted as being deposited under the influence of repeated waxing-waning velocity cycles within multi-pulsed turbidity currents and are termed "multi-pulsed turbidites". Multi-pulsed flow can be initiated by sequences of retrogressive submarine failures in which each slumpi

Turbidity currents are significant due to their role in dictating reservoir sedimentation, the safety of deep sea facilities and the formation of submarine morphological features and turbidites. Interactions exist between turbidity current, sediment transport, bed topography and deformation. However, existing mathematical models have ignored these interactions either partly or completely. Therefore these models can be referred to as decoupled or partially coupled models. Uncertainties arising from these simplifications remain unclear. To help address this, the present study advances modelling

Stream surface albedo plays a key role in the energy balance of rivers and streams that are exposed to direct solar radiation. Most physically based models assume that stream albedo lies between 0.03 and 0.10, based primarily on measurements from low-gradient streams with low suspended sediment concentrations. Albedo should depend upon solar elevation angle, suspended sediment, aeration, and fraction of direct vs diffuse radiation. However, there is no model available for predicting the dependence of albedo on these factors. This study quantified the dependence of albedo of mountain streams on

Flow-bed interaction caused deformation and erosion of the beds and changed the flow structure of the turbidity currents.

<p>Turbidity is an important measurement of water quality, considering it describes water clarity and is an indirect indicator of light transmittance in the water column. Turbidity may impact fish that rely on vision to forage by affecting ability to search for prey. Largemouth bass (LMB; Micropterus salmoides) is a visual predator that may have lower foraging success resulting in reduced growth, reproduction, or survival under conditions of high turbidity. I conducted a field experiment in Wolf Lake, Mississippi to assess impacts of turbidity on diet and distribution and a laboratory experime

One billion of the poorest people in the world today do not have access to improved drinking water. Without treatment, fecal contamination results in an overwhelming disease burden. A long term best practice solution will take decades to implement. In the meantime, approximately 5 million children under five die each year from gastrointestinal diseases. This tragedy can be alleviated by household water treatment. Household Water Treatment and safe Storage systems (HWTS) provide an interim solution. While many low cost and simple technologies exist, none of them are effective against high su

Thesis (M. Eng.)--Massachusetts Institute of Technology, Dept. of Civil and Environmental Engineering, 2009.<br>Includes bibliographical references (leaves 126-131).<br>Unsafe drinking water is a major cause of water-related diseases that predominantly affect people living in developing countries. The most prevalent water-related disease is diarrhea, estimated to kill 1.8 million children every year and the second largest cause of childhood death. Today there are many technologies available to treat unsafe water; however, most of these are suited for use with low turbidity source water. The tr

碩士<br>國立成功大學<br>水利及海洋工程學系碩博士班<br>101<br>Due to fragile geology and steep topography, extremely high turbidity, 10,000NTU or higher, water is frequently observed during a storm event. This extremely high turbidity water could lower the efficiency of water treating process in a water treatment plant or even shut down the water supply. To reduce the turbidity, two types of coagulants can be legally used in a water treating process: (1) inorganic coagulants, and (2) polymer coagulants. The former shows lower efficiency for treating high turbidity water. The latter may introduce healthy risk. There
