Floating Silt Barrier Height
How High are the Silt Barriers Above the Water?
Question: Good morning, My question is regarding the height of the floating silt barriers. How high are they generally above the water? I'm looking at the Type 2 Silt Barrier, heavy duty. I am just looking at specifications at this time as I write an Erosion and Sedimentation Control Plan for a hydroelectric power plant project we are going to be licensing over the next 2-3 years.
Answer: Thank you for contacting us! The Floating Silt Barrier Height will depend on the depth of your curtain and the height of your float. In order to effectively control silt and turbidity in your location, the float height is sized based on the depth of barrier skirt.
Turbidity Curtain Flotation Sizing
In general, skirt depths anywhere from 3 to 10 feet will feature an 8" top flotation device. Skirts longer than 10 feet will typically feature a 12" top flotation to help balance out the skirt depth. In order to determine the best option for your location, we would need to know some information regarding your project, such as water conditions, project length, and required turbidity curtain length and depth. For more information on these turbidity curtains, please check out our Type 2 Floating Silt Barrier.
Additional Erosion Control Information
In addition to the silt barrier, we do also offer several other erosion control products that may be able to help with your project planning. Please check out our Erosion Control Products site for information on erosion control coir logs, erosion control matting and more.
