CONTAMINATED SEDIMENT CONTROL

2015-2016

Engineering and Design Challenges:

  • Loading on System

    • Large enclosed tidal volume

    • Smaller available geotextile filter area, especially at mid to low tide

  • Achieving Adequate Filtration

    • High flux rates (flow per unit area)

  • Transitions:

    • Interface of TRB with SPW top

    • Connections between full-depth barrier and SPW section

  • Barge Gate Design and Operation

Solutions:

  • Robust anchoring elements

  • Custom filter composite

  • Durable transition interfaces

  • Innovative access features

Outcome:

  • Compliance achieved – monitored daily at six water quality testing locations

  • Design aspects adjusted and addressed during installation and commissioning period due to quick/shorter design period
