Floating Silt Curtain & Water Flow

FAQ: Will the Floating Silt Curtain Stop Water Flow?

Question: Will a floating silt curtain stop water flow? I am going to be installing a floating silt curtain in our river, but I am concerned that it will stop the water flow and create stagnant water. Is this a possibility when using the floating silt curtain? Is there anything that I can do to prevent this from happening?

Answer: In general, turbidity curtains are not designed to act as water impoundment dams. When using this curtain, especially in a significant volume of water, it is not expected to stop the flow of water. As an overview, turbidity curtains are intended to trap sediment and contain it to a certain areas, not halt the movement of the water. Questions regarding this type of water stagnation are common when looking into the use of this curtain. Wondering about the blocking of water is a valid concern, especially when the material being used is impermeable.

Installation of a Silt Curtain

floating silt curtain should generally be installed parallel to the flow

Installation of a silt curtain can also play a factor in determining how the water flows in your location. As a general rule of thumb, the silt curtain should NOT be installed across flow channels. While there is one exception to this rule about Installing Silt Barrier Across Flows, for the most part, curtains should be installed parallel to the flow.

In addition, we also recommend the curtain be at a length that allows for a one foot (1') gap between the bottom of the curtain and bottom of the river. This will allow water to continue moving underneath the curtain, preventing any build-up of materials or water.
