Fluvial Geomorphology and Natural Channel Design
Cory L. Horton, P.E.
This ten hour
online course provides guidance for design of stream restoration projects using
Natural Channel Design. After completing the course the student will have a
greater understanding of when, where, and how to implement Natural Channel Design.
The course content is based on the North Carolina State University Stream Restoration
Institute's publication Stream Restoration A Natural Channel Design Handbook
(128 pages). This publication introduces the reader to fluvial processes, stream
assessment procedures, classification methods, and methods for the design of
stream restoration projects.
This course includes a multiple-choice quiz at the end, which is designed to enhance the understanding of the course materials.
the conclusion of this course, the student will understand the following concepts:

is a complex process. The foundation to a successful stream restoration project
is recognizing the processes that create a channel with dynamic equilibrium
- one that maintains its morphology over time. Natural channel design takes
is an alternative approach to traditional engineering. Natural Channel Design
focuses on the reestablishment of the natural stability of the channel as well
as restoring the structure and function of ecosystems, rather than just the
efficient conveyance of water. Fluvial geomorphology is the study of the processes
that create channels. Knowledge of fluvial geomorphology allows for the understanding
of the underlying problems causing channel instability. Stream assessment, classification,
and survey methods are critical for evaluating degraded channels. Stream assessment,
classification and survey methods are also needed for setting as target restoration
levels (reference reaches) and for monitoring changes to stream systems. Stream
restoration projects using Natural Channel Design can produce long-term dynamically
stable channels, increase wildlife habitat value, improve water quality, and
The purpose of this course is to provide guidance on the design of stream restoration projects using Natural Channel Design. You will be directed to the North Carolina State University Stream Restoration Institute's website to study Stream Restoration a Natural Channel Design Handbook (2003 edition, 2.7MB 128 pages, PDF file format).

processes that govern sediment transport and fluvial geomorphology are vital
to success of any stream restoration project. Stream degradation caused by human
activities is often difficult to reverse. Stream restoration using natural channel
design mimics what the system needs to obtain long-term stability. The methods
taught in this course present a means to create a channel that maintains its
morphology over time while restoring the channel ecosystem to its best state
