Things Required to Complete Any Task: 1. Time 2. Energy 3. Tools 4. Knowledge (data, experience, common sense)

Ways to gain knowledge: Read all you can, SUBSCRIBE TO FREE MAGAZINES {Road & Bridge, Landscape Architect & Specifier News, etc) take classes and attend workshops and conferences, hang out with smart people (listen and ask questions), walk as many streams as possible, keenly observe nature, and when touring a completed project ask a member of the design team what they would do differently.
CLASS GOALS
• One of my goals is to have YOU say “I will never look at a stream the same again”
• Using the conceptual thought process, let’s break down complex problems into manageable units, & think the problem through to a goal-based solution.
• Your job is to think about what I (and other teachers in other classes) teach and decide whether it applies to either your situation, or situations you might encounter in the future
And my daughter, Dana Derrick (age 17) says
“You have to have that brain thing going on.” Actually she was talking about our basset Cleophus figuring out how to climb up on the bed, but hey, it applies here too!! THINKING HARD
HERE!
And rivers meander too, these are natural river functionsIf you can, let your
river be a river!! Let it breathe and
have some freedom!

Let’s straighten this stream just like Grandad did, that worked for the last 50 years, & get that gravel for the driveway too!!!
STEPS IN A PROJECT• Initiate
• Plan & develop goals
• Gather data & analyze
• Conceptually develop how water should flow through the project
• Develop conceptual designs
• Analyze and develop the final design (P&S)
• Construction & Inspection: Original design team members should be involved in construction oversight
• Monitoring
Need To Propose & Refine Project Goals during the Planning Phase
The project goals should clearly define the intent and requirements of the project, specify measurable objectives (range of acceptable DO levels for instance), set parameters for project performance, assist with the design of a long-term monitoring plan, and assist with analysis of long-term project effectiveness.
Both short and long range goals should be set and can include:• Project justification (why built, benefits, drawbacks).• What the project will do (expected performance, safety, accessibility, multiple uses).• What physical parameters of the stream (or surrounding area) will be affected (slope,
sinuosity, thalweg location, substrate type and size, bank shapes, cross-sectional area, riparian corridor effects, etc.)?
• Impacts to the environment (construction impacts, WQ, terrestrial and aquatic habitats (improve, degrade), long term effects (reduction in diversity of habitat, etc.), ways that possible adverse effects can be mitigated).
• What the project will not do (vertical stability or possible adverse effects downstream not addressed, etc.).
• Estimated project life, and the amounts of monitoring and maintenance needed to ensure a productive project life.
• GOALS WILL GUIDE FLOW VISULIZATION, STABILIZATION TECHNIQUES USED,AND MONITORING ANALYSIS REQUIRED
GOAL: a broad statement that reflects a desired outcome
OBJECTIVES: are specific statements that state GOALS in measurable terms
PERFORMANCE CRITERIA: values, or a range of values used to evaluate the functional performance of a project

Purloined from Gerry Hester, Southern Nevada Water Authority
Stabilizing a stream is sometimes kind of like grabbing a snake in the middle!
Luxuries We Like To Have• The “Luxury of Space”• The “Luxury of Time” (nature
strengthens the project over time)• The “Luxury of Monitoring”• The “Luxury of Adaptive Management”
Think conceptually regarding functions, use Derrick’s “LAW OF EXTREMES” to understand how things work. Example-ditch narrow & deep, or 5 ft wide & 1 inch deep
The First Site Visit• Is always the most important site recon.• The best decisions are usually made in the field during the first site visit.• All project shareholders, interested persons, and agency personnel who will
comment on the permit should be present. Experienced personnel should be involved. THINK INCLUSIONARY, NOT EXCLUSIONARY!!!!
• One facilitator (without an agenda) should EXTRACT goals (both long and short term) and knowledge from the group. Understanding and hopefully compromises should be reached on conflicting goals.
• Existing flow and erosion processes should be analyzed. How water needs to flow through the project (related to project goals) and what functions need to be restored, should be discussed in a conceptual manner.
• Conceptual designs should be formulated so as to make water behave as required (what structures/plantings are needed?)
• The effects of the proposed project on the stream and riparian area should be analyzed (near field, far field, upstream and downstream). Future changes in the stream system and their effects on long-term project performance should be examined.

Engineering:When in over your head, go get
help! Dr. Biedenharn says that at the end of this
workshop, “the class participants should have a higher level of confusion, similar to the level of
confusion currently experienced by the instructor(s)”!
IF ANYONE SAYS THEY HAVE ALL OF THE ANSWERS, THEY DON’T!!!
NO SURPRISES!! *NO DRAMA! *NO BACKING UP!!PROJECT MANAGEMENT
• First thought from regulatory ….. Avoidance & minimalization….
• List all alternatives – not just your best plan. Show how U have minimized already.
• Regulatory folks are 99% biologists, emphasize the effects of the project on the planet. Hint: roughness = habitat…
• Regulatory wants it done correctly, once!!
PERMITS - get regulatory involved early
Never be something that you are not!!
Teamwork is key!!
THINK INCLUSIONARY
NOT EXCLUSIONARY
Results of Monitoring • Determines if project goals were accomplished
• Detects the need for maintenance or repair in a timely fashion.
• Provides a basis for designing repairs, if needed.
• Detects changes in stream characteristics.
• Provides valuable insight into stream behavior, & long-term performance and effects of stabilization works
• After appropriate analysis, design criteria for future stabilization works can be improved.
From Charlie Elliott
Levels Of Monitoring EffortLevel 1: Visual observation of the site with written report.
Level 2: All activities performed during a Level 1 monitoring effort plus a permanent photographic and\or videotape record of the project area. Photos should be shot from fixed and marked locations (GPS).
Level 3: A Level 2 effort plus some physical measurements of the site (possibly using the typical low-flow water surface elevation as a datum).
Level 4: Level 3 effort plus a comprehensive survey of the stream.
Level 5: "The Whole Tamale". Level 4 monitoring effort plus any additional data deemed relevant, including, but not limited to: sediment size and gradation; water quality; roughness and conveyance analysis; fish habitat and biomass analysis; etc.
NOTE: Monitoring should also take into account the pre-project history of the site and whether project goals and functions were achieved. Some members of the original design team should be on the monitoring team.
Maintenance Considerations• Even properly designed works require some maintenance eventually.
• The ability of the designated agency to perform maintenance needs to be assessed during the design phase.
Why is Maintenance Required?• Was damage due to conditions that are not expected to recur?
• Was the original design criteria not conservative enough?
• Is the method itself at fault?
Aftercare
You will never get everything correct the first time around
• If you do it was a miracle
• Or you are the luckiest person on the planet
• Or it has not rained yet
• Or the project is overbuilt
• All projects should take two years to construct. Build it, monitor over the first year, then repair & apply adaptive management as required (based on project goals), then monitor some more.
TOP 6 REASONS THAT I SEE STREAM PROJECTS FAIL
• Inadequate keys!!! Not vegged & do not go far enough up the hill
• Project goals and functions not thoroughly thought out• Start and end points wrong (project did not go far enough
upstream or downstream, or both)• Scour at the toe, or foundation failure of foundation –
dependant stabilization methods• Inappropriate use of redirective methods• Folks simply did not understand where water was going
and what was guiding it. YOU HAVE TO THINK LIKE WATER AND SEE WHAT WATER SEES!!!
