CIVL 455 River Engineering Units: 4.00
A course in the basics of river engineering including the study of alluvial processes, the prediction and consequences of sediment transport, the design of measures to control erosion and accretion, and the design of dams, spillways and diversions. Cristical aspects in the design of river engineering structures and assessment of environment impact of river engineering projects are discussed. The use of physical and numerical models in the practice of river engineering is illustrated. The principles of natural channel design, stream restoration, and bioengineering in river environments are also addressed.

Course Learning Outcomes:
- Gain knowledge of a river as an object with a movable boundary and a conveyor of a two-phase flow (water = liquid phase; sediment = solid phase).
- Gain knowledge about the mechanical properties of flow, including shear stress and velocity distributions, and the physical properties of sediment and sediment mixtures.
- Understand the mechanics of sediment transport, and learn to quantify bed-load and suspended-load sediment transport rates.
- Gain knowledge of river morphological features (ripples, dunes, bars, meandering and braiding), their dynamics and implications of their occurrence.
- Gain knowledge about common river engineering problems and solutions, including prevention of undesirable bed and/or bank erosion and deposition, prevention of stream incision, techniques for stabilization of river course, techniques for modification of river course, and principles of stream restoration and renaturalization.
- Gain knowledge about mathematical models commonly used in river engineering practice for the simulation and prediction of river flows and their physical and environmental impacts.
