Between balancing the complex physical and biological elements and attaining needed improvements, stream restoration can be challenging. An integral aspect of stream restoration is the ability to see the watershed as an ever-changing landscape that greatly influences the stream restoration methods and design. In this short course, we will go over these two main topics.
In this session, we'll explore fluvial geomorphology and its relationship with watershed, including common terms and watershed elements, stability and instability definitions and conditions, and causes of river instability. Additionally, we'll discuss watershed hydrological classification, channel profile and shape, and limitation of channel layouts for stream restoration projects.
Then we will move beyond river behavior and into the computational tools you can use to determine design features for restoring streams based upon fluvial geomorphologic theories. We'll continue the discussion with various channel forms and their important features, as well as explore the Rosgen stream classification system, guidelines, and best practices for use.
The hydrology of the watershed will be discussed and how to determine appropriate design discharge for use in developing the main channel geometric design and overbanks area. In addition, hydraulics and channel dimensions in relation to the design discharge will be discussed in relation to the main channel width, depth, and slope design.
Additionally, we'll discuss the key elements of successful stream restoration projects and team development. Within this discussion we will outline the best practices in stream restoration needs, including: identification, development of timelines and project objectives, and identification of design team disciplines and expertise requirements. And finally, we'll take a look at how to best interweave these elements in your planning to produce a sound, successful, and sustainable stream restoration project.
