Workshops - Streambank and Soil Bioengineering Treatments

Synopsis

This course is designed to give the trainee an introduction into riparian ecology, riparian vegetation, and stream dynamics.  With this basic information, the trainee will learn about Streambank Soil Bioengineering Treatments that use vegetation to stabilize eroding streambanks with or without inert material.  During the course, participants will also design a bioengineering project and install various bioengineering treatments in a real stream situation.

Objectives

Upon completion of this workshop, the participants will be able to:

  • Assess the problems that caused the stream to erode
  • Prioritize the sites that need treatment
  • Inventory the eroding sites
  • Develop a restoration plan
  • Design the streambank bioengineering treatments for each specific site
  • Install the various treatments in the design
  • Develop a monitoring and Maintenance plan

Prerequisites

Basic understanding of riparian areas and stream processes including riparian plants and establishment techniques.

Duration

This class is a 3 day course.  The first day and a half is in the classroom where riparian ecology, principles of bioengineering, introductory hydraulics, hydrology, fluvial geomorphology, and sediment transport, riparian plant identification, riparian plant propagation, and streambank bioengineering treatment installation are covered.  The afternoon of the second day is in the field where the students will inventory an eroding stream section, discuss potential bioengineering treatments, and develop a treatment plan.  On the third day, the final treatment plan will be discussed.  Then, the different streambank bioengineering treatments in the plan will be installed by the trainees.  Depending upon site specific conditions and project goals, these may include:  brush mattress, fascine, vertical bundles, willow pole planting, tree revetments, brush spurs, etc.  The students may also collect willows for the various treatments and process them.

Target Audience

Federal, state, and local agency conservationists and professionals, tribal members and employees, landowners, consultants, and contractors involved in river restoration.
