Alternatives to Rip Rap - Environmentally-Sensitive Stream Stabilization Methods and Case Studies
8:00 AM - 4:00 PM

In 2005 the Transportation Research Board received a “problem statement” from its member Highway Department DOTs – “Are there any alternatives to the traditional bank and channel protection measures, such as riprap, gabions, cable-tied blocks, or grout-filled bags, that offer beneficial “in-stream functions”, such as: habitat diversity, fish passage, water quality and aquatic habitat?”

 A 3-year research project was awarded to Salix Applied Earthcare to develop a list of environmentally-sensitive methods, such as bioengineering, root wads, large woody debris, bendway weirs, and engineered riffles, intended to protect highway facilities from erosion, incision, and lateral migration. 

This course is presented by the research Principle Investigator who is also a CPESC, fluvio-geomorphologist, and bioengineering practitioner who also, as a Licensed Contractor, has been building and monitoring dozens stream projects that utilize NCHRP Report 544 as “the basis of design”.  

Techniques that are 30% cheaper than riprap and get stronger with time. Not only will the techniques be presented, both before, during and after construction but other topics will be covered also, such as; the use of clean, self-launching (well-graded) stone to facilitate construction with no water quality impacts, the use of re-directive, thalweg management strategies that effectively move the high velocity flow vectors away from the sensitive banks, and the use of biotechnical methods that combine vegetative and structural in a mutually beneficial manner. Methods that grow stronger with time.

The “proof is in the pudding” so this course is packed with documented case studies using photos and Dirttime.tv video clips. See the techniques employed in Alberta, AK, New Zealand, California, and Malaysia.

BMP Selection to Improve Your Watershed
8:00 AM - 4:00 PM

Selecting the right Best Management Practices (BMPs) is crucial for protecting and improving watersheds, but understanding the array of choices and the conditions in which different BMPs are most effective can seem overwhelming.  

This comprehensive workshop guides program managers and engineers through the criteria necessary for selection of the most effective BMPs for a project. It begins with a discussion of pollutant types and their sources, moving into an overview of pollutant removal unit processes, followed by a discussion on regulations for impaired waters, NPDES, TMDLs, and numeric nutrient criteria. The next part of the course addresses the difference between new development BMP design and retrofitting existing development for TMDL compliance. 

A detailed description of dozens of BMPs is given—from ponds, alum injection systems, and constructed wetlands, to various types of media filters, inlet devices, sand filters, hydrodynamic devices, and more. Low-impact development and green infrastructure methods and applications will be demonstrated. A section on selection criteria gives participants a list of factors for making the best choices, including not only pollutant removal effectiveness but also types of pollutants, available space, groundwater level, soil type, and maintenance costs. The workshop also includes discussions of first flush, monitoring of BMPs, and BMP removal efficiency databases. Several computer models and case studies of pollutant loading calculations for TMDL compliance and pollutant removal calculations for BMPs and treatment trains are demonstrated. An in-depth look at BMP inspections and maintenance will also be given, along with a method to track sediment removals from street sweeping and maintenance activities to achieve reductions in TMDL allocations.

Fluvial Geomorphology and Stream Restoration
8:00 AM - 4:00 PM

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. 

Fluvial Geomorphology
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.

Stream Restoration
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.
