Participants….
Stream Restoration or Naturalization
• The return of an impaired or degraded river corridor ecosystem to a close approximation of its remaining natural potential (as defined by habitat quality, quantity, species richness/diversity)
• Not to its original or undisturbed condition
Habitat degradation often is driven by stream channel degradation and instability
How does one become an effective practitioner in Stream Restoration?
Fluvial GeomorphologyThe processes controlling river channel form and river channel change, their causes and stimuli, and their time and space scales
River EngineeringThe geotechnical and hydraulic corrective measures designed to create a dynamically stable, multifunctional river corridor
Aquatic EcologyThe biogeochemical interactions between species and their environment, including ecosystem assessment and integrity
Social and economic context
Goals of Lectures
• Provide an introduction to the main topics in fluvial geomorphology
• Academic and applied approaches– Stress physical processes– Blend of earth science and engineering
• Mix of classic and emerging trends in fluvial geomorphology
Working knowledge of river processes and forms, river channel change, and critical concepts of river restoration
Categories of Lectures
Basic principles in fluvial geomorphology and river mechanics
Case studies of river corridor assessment
Topical seminars on fundamental and applied aspects of river process and form
Tools and technology available to assess river processes and river channel change

Additional Activities
• All registered graduate students will be asked to do additional work to satisfy their course requirements
• There will be two (2) early evening “jam” sessions (M & W), additional players, singers, rock stars, and groupies are welcome (affinity for classic, southern, and blues rock is desirable)

Conclusion
• Ecosystem or water quality impairment in rivers often is intimately associated with stream channel (dynamic) stability
• Effective practitioners in stream restoration meld fluvial geomorphology, aquatic ecosystems, and engineering solutions
• Here we will examine the basic principles of fluvial geomorphology, complemented by case studies of river corridors, topical seminars, and tools and technology
