How Do You Choose A Bank Protection

Method? A delicate balance is

required, as demonstrated here by Roundman

Chosen method (or combination of methods) must meet the 3 E's:

• Economics

• Engineering

• Environmental

Determining the Best Method(Need To Rank and Assess Possible Choices)• Cost

• Level of protection• Degree of confidence in method• Identify other benefits in addition to bank stabilization (environmental,

aesthetics, accessibility).• Is upstream reach stable?• Effects of bank protection upstream and downstream of project. Will this

project blend with future bank protection projects?• Do you have the “Luxury of Space”?• Do you have the "Luxury Of Time"? Can you try a minimal approach that will

strengthen over time.• Practicality, constructability. Is specialized equipment needed? Is the

contractor familiar with the techniques?• List other design considerations (endangered species (both aquatic and

terrestrial), boating, fishing, swimming, and other recreational impacts, etc.)• Is the method experimental? If so, inform all parties !!

(From Charlie Elliott)

Goal and Function-Based Design will determine what you will use for your project

(WHAT IN THE WORLD ARE YOU TRYING TO ACCOMPLISH?)

Page 6: How Do You Choose A Bank Protection Method? A delicate balance is required, as demonstrated here by Roundman Chosen method (or combination of methods)

What If The Bank Protection Fails?• What effects will failure have?• Perform risk analysis of failure modes for protection

techniques involved. Are protection techniques foundation dependent?

• What will be threatened if failure occurs?• What will effects of failure be upstream and

downstream?• What will it take to fix it? • How much money will be needed for repairs?• How much time will be needed to repair?• Can you get back to the project? Access?????

Each Streambank Erosion Problem Is Unique, And Will Therefore Require A Unique Solution!

• There are no "cookbook" solutions in river and stream stabilization!• There is a time and place for most every type of stabilization method.• Do as much for mankind & our planet as possible (multi-functional

design is preferred). Think early in project of other benefits and uses.

• Multi-disciplinary design team approach works best, learn from other professionals, bounce ideas around (brainstorm). Use common sense, look for nearby successful projects.

• Think in angles, look where water is going, see what is guiding and controlling water (bank angles, kickers).

• Thoroughly think proposed plan through. Work within your strengths, know your limitations! Get help when needed!!

• Identify maintenance needs, monitor project (even informally) • Learn from what you do. When touring a project ask the design

team what they would do differently.

Be careful with transitions-good one here, Hickahalla Cr. Senatobia, MS.

All transitions must be smooth, note gradual transition from low LPSTP to full bank paving protection

DEMONSTRATION PROJECTS

• From a research/demonstration project point of view there are typically two things to prove: that a given untried innovative bank stabilization method will in fact work on a specific river or stream and/or specific energy environment, and some of the demo project should fail to some degree so as to determine exactly what the minimum effective effort should be. In other words what is the lower limit? The project should be weaker/lower in the downstream direction.

• There should not be anything of value on the bank or in the near vicinity so when partial or total failure does occur valuable commodities (infrastructure, park facilities, natural resources) are not threatened.

What If You Have No Money? Or Too Much!(The Stream Is Falling Apart, What To Do?)

• Focus on a relatively short reach, or reaches, undergoing severe problems. Need to sell folks on the importance of the project. There is usually money available somewhere (landowners, demo money, Fed funds, etc.).

• Use expert assistance to analyze problems and recommend cost-effective solutions. This might be your only chance, at least part of the project has to be successful.

• Put something in the ground - call it a demo project, training exercise, etc. Get landowners or agency personnel to help (hands-on training workshops).

• If possible, use several variations of a few different methods. • If funds are really limited spend money at the toe. Use materials that can

adjust. Allow nature to strengthen project over time.• Monitor. Repair if needed. Publicize results.• Once you can show what works for your stream, then go about securing

funding to fix the remainder of the stream
