Abstract
A sediment control roll includes a threshold member having large apertures therethrough, a hollow sediment collection chamber, and an outflow filter having small apertures therethrough. The sediment control roll can be used to collect sediment in runoff from a construction site, or to reduce removal of sediment from an existing mass of soil, sand or other sediment. The sediment control roll can for example be made by rolling up extruded polymeric netting with filter cloth attached thereto.
