Turbidity Barrier for River Dredging Project

Question: Hello, I am interested in your river turbidity barrier. We will be dredging in a river and require floating turbidity control. I am looking for around 3000' of barrier. Which type of floating barrier would you recommend for dredging?

Answer: Thank you for contacting us! For dredging applications in moving water areas, the Triton Type 2 or Type 3 Silt Barrier will probably be best for your location. These barriers are designed to handle moving water and we offter both both a heavy-duty and medium-duty models for appropirate support and turbidity control in your area. Ultimately, the river turbudity barrier you will need depends on unique factors specific to your project such as:

  • Water Location Conditions: Possible conditions include, but are not limited to:
    • Water Velocity (speed and movement of the current)
    • Waves (how high are the waves? how often do they occur?)
    • Tides (variance, etc.)

  • Site & Project Conditions: These include both environmental and some project related factors.
    • Wind (speed, frequency)
    • Project Duration
    • Type of Silt or Turbidity (are these particles contaminated? how much needs to be contained?)

Once these factors are considered, the correct river turbidity curtain can then be chosen to help contain and segregate the area. Not sure which floating river curtain is right for you? See our curtain comparison chart, or call our experts at +1-772-646-0597.

River Turbidity Barrier Design

The construction of Triton Turbidity Barrier are designed to provide you with increased control in your site or location. Triton designs include:

Marine Grade Flotation: Each barrier is equipped with a marine grade flotation that has been installed into the top portion of the barrier. This flotation varies in size (6", 8", 10" or 12"). The size of the flotation device is dependent on the depth of curtain on your unit.

Fabric: The typical fabric used for these barriers is a reinforced PVC. Turbidity barriers are usually constructed with impermeable materials that prevent silt from flowing through, but permeable filter panels can be accomodated to allow water flow through the barrier. Permeable filter panels can be used on barriers that contain a long skirt or are in high flow areas to help relieve pressure on the unit.

Bottom Chain: In order to effectively control the turbidity in your area, these barriers are designed with a bottom steel ballast chain that helps keep the barrier vertical. Although the chain helps keep the curtain in place, anchoring is essential to maintain correct positioning for control under the surface.

Section Lengths: Regardless of your required barrier size, these products are manufactured in section lengths of either 50 or 100 feet. Iindividual sections that link together can be easier to manage and install.

All barriers can be connected via bolt rope reinforced grommet section ties.

Choosing your River Turbidity Barrier:

Determining which type of barrier you require can depend on a wide range of factors including:dredging river barrier

  • Velocity of Water
  • Speed of Wind
  • Height of Waves
  • Type of Turbidity Being Contained
  • Duration of your Project
  • Surrounding Site Conditions
