CCE 59700 – Physical Aspects of Stream Restoration
Credits and contact hours
3 credits
Lecture meets 3 times per week for 50 minutes per meeting for 15 weeks
Specific course information
Catalog description: As this course is still considered experimental, there is no description as yet in the catalog. It however discusses basic hydrological, hydraulic, sediment-transport, and fluvial geomorphical aspects related to stream restoration, including concepts of bankfull quantities, regional curves, scaling, water and sediment conveyance, stream classification, and channel stability.
Prerequisites: CCE 34000 or equivalent with minimum Grade of C-
Course status: Elective course
Specific goals for the course
Student learning outcomes - Upon successful completion of this course the student shall be able to understand and apply the basic physical concepts arising in stream restoration problems, including:
estimating design discharges for gaged and ungaged streams
applying regional curves for hydrology and hydraulic geometry
analysis of streambank stabilization, and designing riprap as well as other bio-engineering and flow-redirection approaches
the application of the analytic approach to the design of stable channels
Relationship of course to program outcomes
Outcome 1: An ability to identify, formulate, and solve complex engineering problems by applying principles of engineering, science and mathematics.
