  • Fish Passage and Screening Design

    Credits: 4 PDH

    PDH Course Description:

    Fish passage and screen facility design is often a significant component in stream restoration and water resource management. A wide variety of issues often arise regarding passage and screening design, depending on the project region and species of interest.

    This course provides an overview of fish passage and screening design approaches that incorporate biological considerations into the hydraulics of commonly used structures; guidance on site assessment and operations and maintenance (O&M) of fishways and screens; an overview of assessment and design approaches for fishways and screens, ladders, culverts, tidegates, and floodgates; and finally, an example design is presented.

    Topics:

    • Passage barrier and screening overview
    • Biological design considerations
    • Migration type and schedule
    • Fish passage and screening design
    • Site assessment
    • Hydrologic analysis overview and hydraulic models
    • Concrete fishways and ladders
    • Weirs, orifices and gates (flow controls)
    • Concrete ladder pools
    • Entrance, exit, and attractors
    • Rock fishways
    • Roughened channel fishways
    • Engineered channel
    • Culvert modification and design
    • Tide gates and floodgates
    • Fishway operation and maintenance
    • Fish screen and bypass
    • Maintenance and operation
