Course content

This two-day seminar is intended to provide an opportunity to share some common problems and potential solutions with a wide range of individuals involved in the post-flood restoration challenge. It will also provide a forum for consultants, agencies, land owners, and entities responsible for restoration efforts to get to know one another, "neighbor-up", and initiate a dialog to assist in a coordinated and integrated approach that utilizes many disciplines. Most importantly, this dialog should help direct and coordinate efforts to be consistent with commonly shared objectives.

Dave Rosgen will present the fundamental principles and post-flood applications using a Natural Channel Design approach for River Corridor Restoration. Participants will have ample opportunity for open dialog to ask specific questions throughout the seminar.

Day 1 – All day lecture that will cover a broad range of topics, including:

  • Common problems and solutions following floods
  • The concept of a "master plan"
  • The ten phases of natural channel design
  • The use of stream and valley types to develop reference reach (stable river) data for extrapolation and scale adjustment to impaired river systems
  • The extrapolation of proposed typical design scenarios for widespread and rapid application under time and financial constraints
  • Recommendations for post-flood restorations and case examples of past projects

Day 2 – All day field visit to observe and discuss various post-flood impacts involving typical impaired reaches, including:

  • Irrigation diversion structures
  • The urban river reach
  • Bridges, culverts and road impacts
  • The aggrading reach
  • The degrading reach
  • Accelerated streambank erosion
  • Hillslope processes contributing sediment
  • Conceptual restoration design recommendations presented at each reach representing various processes and impacts.
