    Credits: 3 PDH

    PDH Course Description:

    This course outlines the general description, advantages, and disadvantages for most indirect techniques used in bank stabilization methods. Indirect protection structures extend into the stream channel, and redirect the flow so that hydraulic forces at the channel boundary are reduced to a non-erosive level.  

    Indirect protection techniques can be classified as follows: Permeable dikes, Impermeable dikes, Retards, Permeable retards, Impermeable retards, Other Flow Deflectors, Bendway weirs and Iowa Vanes. Additionally, there is a section ath the end, regarding vegetative methods for erosion protection.

    Topics:

    • Dike and Retard Erosion Protection Structures
    • Advantages and Disadvantages of Dikes and Retards
    • Typical Applications and Design Considerations
    • Permeable and Impermeable Dikes and Retards
    • Uther Flow Deflection Methods
    • Iowa Vanes and Bendway Wiers
    • Vegeatative Methods for Erosion Protection
