Sediment Transport

Course Description

Analysis of the interaction between fluids and solids. Mechanics of sediment transport, incipient motion, bed forms, bed load, suspended load, wash load and total load. Practical applications of sediment transport in open channels and reservoir sedimentation.

Course Objectives

To gain a sound understanding of the principles of Newtonian Fluids; to model the spatial and temporal scales of turbulent structures as they relate to pathways of sediment particles. To investigate the incipient conditions of sediment motion (for non-cohesive and cohesive sediments), entrainment of sediment, bed load and suspended load, in gravel and alluvial channels. To study bedforms and their effects on frictional characteristics. To apply the principles of hydromechanics and sediment transport in several sediment entrainment problems (e.g., dikes, secondary flows, mountain streams). To identify sediment source, fate, and impact in natural systems. To understand basic concepts of scaling and their application to physical models. To understand principles of computational river dynamics and to apply the principles to solve governing flow and sediment transport equations. To become familiar with the use of several existing hydrodynamic/sediment transport models including FLUVIAL, SED2D-FESWMS, 3ST1D, SMS-SRH2D. In addition to lectures, movies, laboratory demonstrations and a field trip will be used to visualize and explain various phenomena encountered in natural rivers.

River Mechanics

Course Description

This course explores the rich and complex field of fluid mechanics, sediment transport, geomorphology and contaminant transport pertaining to river mechanics. The emphasis of the course is on river equilibrium, river dynamics, bank erosion and stabilization as well as river training. These topics are introduced and complemented with the application of different open-source and in-house computer simulation models. Students learn how to design several countermeasures to reduce the effects of flow on bank erosion, improve stabilization and maintain suitable aquatic habitat.
