Abstract
A reinforced silt retention material with a variable sieve capability is provided for use in soil erosion control applications. The reinforced silt retention material includes a sheet of water permeable filtering material having varying apparent opening sizes at a series of filtering zones defined along the sheet, which allows varying amounts of runoff water to pass through the sheet but resists the passage of silt and debris therethrough. The silt retention material further includes one or more reinforcing elements that provide additional support to the sheet to protect against tearing and/or undue movement of the sheet, as well as provide attachment points for fasteners used to fasten the sheet to support members for proper positioning during erosion control applications.
