Purpose and Background

Stream Classification and Geometric Determinations for Restoration Projects

Between balancing the complex physical and biological elements and attaining needed improvements, stream restoration can be challenging.  But water resources expert and prolific speaker Dr. David T. Williams is here to help! Join us for this live, educational webinar as Dr. Williams walks through an actual stream restoration project and discusses the important ingredients to a successful project.  Whether new to a stream restoration team or an experienced practitioner, this course provides a comprehensive overview of the stream restoration process from assessing the need for rehabilitation to actual design (with example project construction plans).

Streambank Protection Design: Hard & Soft Techniques & Application

When restoring and protecting the banks of your streams, lakes, excavated channels, etc., there are plenty of vegetative plantings, soil bioengineering, and structural systems to choose from. The challenge comes in what to use when, where, and how.  Join prolific speaker Dr. David T. Williams for this live, educational, webinar to explore the “hard” and “soft” designs, techniques, and applications for streambank protection and how you can best select and apply them to your projects.  We will start with a discussion on streambank erosion, including its contributing factors and key considerations. Williams will then walk us through the available streambank protection solutions and how you can determine those most ideal for specific project conditions. He will outline the applicable hydrology, hydraulics, and soil equations and how to incorporate these into your solution selection.

We will also take a look at design and installation best practices - including how you can combine "hard" and "soft" techniques for maximum protection and an enhanced habitat - and examine solution maintenance and performance assessment.

Benefits and Learning Outcomes

Upon completion of this course, you will be able to:

• Explain the stream restoration process
• Assess the need for rehabilitation
• Apply design to stream restoration
• Apply “hard” and “soft” designs, techniques, and applications for streambank protection
• Explain applications for streambank protection
• Select and apply applications for streambank protection

Assessment of Learning Outcomes

Achievement of the learning outcomes by attendees will be assessed through in-class discussion, case studies, and a short post- test assessment (true-false, multiple choice and fill in the blank questions).
