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
