Under considerable flow conditions, a type III floating turbidity curtain may be used when flow is less than how many feet per second?

A type III floating turbidity curtain is specifically designed for use in situations with moderate to high water flow. In the context of sediment and erosion control in Florida, these curtains help to contain and filter out suspended particles in water to mitigate environmental impacts.

When considering the maximum flow condition for effective use of a type III curtain, it is commonly established that it should not exceed 5 feet per second. This threshold ensures that the curtain can effectively function by maintaining an adequate barrier against the flow of water and preventing sediment from dispersing beyond the containment area. Exceeding this flow rate may compromise the integrity of the curtain, leading to potential failure in sediment control, resulting in more pollutants entering the waterbody.

This specification is important for practitioners in stormwater management to understand, as it helps them select the appropriate control measures based on site-specific conditions.
