Incipient resuspension of silt-clay deposits in oscillatory and unidirectional flows

Creator:: Talebbeydokhti, Nasser
Abstract:: Incipient motion of cohesive sediment and the role of flow parameters were investigated for separate and combined unidirectional and oscillatory flows. Sediment from Sturgeon Lake, mainly silt and clay with organic matter, was used as bed material In recirculating and wave flumes. Bench-type experiments indicated that when the submerged sediment...

Sediment transport beneath an undular hydraulic jump

Creator:: Broome, Robert
Abstract:: Field observations are made of the formation of backwash ripples on the beachface, formed by undular hydraulic jumps generated by backwash down the beach face colliding with wave bores. Measured ripple wavelengths range from set averages of 48 to 70 cm. Within a particular set of ripples there is a...

Bed material routing and streambed composition in alluvial channels

Creator:: Jackson, William L. (William Longstreth)
Abstract:: A descriptive model of bed material routing was developed for alluvial streams exhibiting sequences of pools and armored riffles. The model assumes that channel geometry, sediment transport competence and the availability of sediments for transport are all non-uniform in the downstream direction. Bedload transport is described as occurring in two...

Sediment transport in a gravel-bottomed stream

Creator:: Milhous, Robert T.
Abstract:: Sediment transport in a gravel-bottomed stream located in the Oregon Coast Range was studied to determine the effects of a single layer of large particles (the armour layer) located at the surface of the bed material. The bed load transport system was studied jointly with suspended sediment transport to understand...

The Effects of the Flow Regime on Stream Channel Form and Processes

Creator:: Hempel, Laura A.
Abstract:: Numerous studies have explored how alluvial channel size and morphology are adjusted to different sediment and flow conditions, yet we still know very little about how and to what degree the flow regime controls channel form and processes. We use the term ‘channel form’ to refer to the size and...

DNS study of Particle-bed-Turbulence Interactions in Oscillatory Flows

Creator:: Ghodke, Chaitanya Deepak
Abstract:: Turbulent flows over rough surfaces are encountered in many engineering and geophysical applications. Flows of this nature, due to their increasing technological interests, have been a subject of rigorous investigation in recent years. Of the particular interest to the oceanographic community is the study of turbulent oscillatory flow over rough...

Observations and prediction of intermittent sediment suspension in the surf zone

Creator:: Yoon, Hyun Doug
Abstract:: In this dissertation the interactions between hydrodynamics, sediment suspension and transport, and morphological evolution in the surf zone was investigated with a large-scale laboratory experiment data, CROss-Shore Sediment Transport Experiment (CROSSTEX). The data set included comprehensive measurements of water surface elevation, fluid velocity, sediment concentration, and morphology for irregular waves...
