CEE 6035 Special Topics in Hydraulics: Elements of Sediment Transport
Lecture: TR 11:40-12:55 (Jan 27-Mar 2, 2016) HLS 320
The study of the motion of gravel, sand, and silt in flows of water. Traditional descriptions and more recent mathematical models for sediment transport and related dynamics: rolling, sliding, jumping, collisions, and turbulent suspensions. Instability of the bed and evolution of bed geometry.
Mass and momentum balance in the context of sediment transport and bed geometry; Particle properties, grain size distributions, and fall velocities; Channel hydraulics, turbulence, and bed stresses; Threshold of motion, bed-load transport, turbulent suspension, and wash-load; Mixtures and sorting; Bed geometry and bed-forms. Quantitative model development will include: Incipient motion; Saltation; Collisional interactions; Turbulent suspension; Bed instability; and Bed-forms.
There will be four homework assignments and a take-home project in the final week. The project will be based on the backgrounds and interests of the students. Each assignment will count equally toward the final grade.
