2011 Short Course
Assessment and Sediment-Based Design of Stream Restorations
Participants will learn assessment and design techniques that have been implemented by the University of Louisville Stream Institute in several Kentucky stream and wetland restorations. In these restorations, floodplains and stream channels were reconstructed to reestablish the historic surface and subsurface processes that would have occurred at the sites prior to human-imposed changes to the watershed’s hillslopes, valleys, and stream channels. These self-sustaining restorations have the capacity to adjust to changes in the watershed; they are able to maintain grade control and stable habitat without being constrained to a fixed form that would be necessitated by structures commonly installed to direct flow through the channel. Other objectives addressed by these techniques have included
- Increase in volume and duration of groundwater storage in the valley, surface water storage in the floodplain, and base flow in the channel
- Re-creation of dynamic hydroperiod of floodplain inundation
- Facilitation of hyporheic flow around and under the channel
- Attenuation of flood flows
- Increase in potential for reduction in TMDL pollutants (e.g., through nutrient processing and storage of fine sediments)
- Reduction in delivery of fine and coarse sediments to downstream reaches
- Improvement of habitat for rare, threatened, or endangered species
- Facilitation of aquatic organism passage
- Colonization of riparian area by volunteer wetland vegetation species
The 10-day course will be delivered in three parts:
Part 1: Assessment of Sediment Loads and Habitat Impairments. Part 1 will be offered Monday through Thursday, April 4 -7, 2011. This 4-day segment will provide an introduction to the design concepts to be covered in Parts 2 and 3. Lectures, class exercises, and fieldwork will illustrate techniques for assessing sediment sources and loads and for identifying important geomorphic processes occurring on a watershed scale and their impact on stream stability, bank erosion, sediment supply, and stream habitat. At the conclusion of this segment, participants will develop conceptual design alternatives.
Parts 2 and 3: Sediment-Based Design of Stream Restorations. Parts 2 and 3 will be delivered over two 3-day periods: Tuesday through Thursday, June 7-9, 2011, and Tuesday through Thursday, July 12-14, 2011. Completion of Part 1 is a prerequisite for Parts 2 and 3. These two parts will cover techniques for completing detailed assessments (bed material load, site geotechnical characteristics, and groundwater and channel hydrology) and using them for design. Students will also be introduced to the application of two-dimensional flow modeling to floodplain and channel design. Lectures, class exercises, and fieldwork will guide participants through the development of design alternatives and important components of a detailed design for a section of a stream and floodplain restoration.
Who Should Attend
The course is intended for professionals involved in conceptual design, detailed design, or review of stream restorations. Likely participants include environmental consultants; representatives of non-profit agencies; and government agency personnel. Previous completion of other short courses is not required; the course content will be significantly different from most other available restoration courses. Due to the technical content of the course, however, a working knowledge of engineering concepts and methods is recommended but not required.
Dr. Art Parola, PE, Director of the Stream Institute and Professor of Civil and Environmental Engineering at the University of Louisville, will lead the course along with specialists in the fields of geomorphology, characterization and transport of sediments, natural channel forms and design, and water quality.
The registration fee will be waived for government employees. For all other registrants, the fee for the course will be $1795 and will include tuition, course materials, and transportation to field sites.
Meeting and fieldtrip locations will be primarily in or near the central Kentucky cities of Frankfort, La Grange, Lexington, and Louisville.
Participants will be eligible for 70 professional development hours. A certificate of completion will be provided only to those who attend the entire training.
Enrollment will be limited to 30 participants who can commit to attending the full 10-day course (Parts 1-3). Go to http://louisville.edu/speed/civil/si/2011course/apply to submit an application by December 1, 2010.
Applicants will be notified by December 20, 2010, of their acceptance. Registration forms and payment will be due by February 1, 2011.
