24 - Geosynthetics in erosion and sediment control

Abstract

Erosion and sediment control systems have been developed to help satisfy regulations designed to prevent sediments from reaching surface waters. Geosynthetic-enhanced erosion and sediment control systems perform unique and quantifiable functions while introducing ever greater versatility and cost-effectiveness. Geosynthetics are now commonly used along with temporary degradable materials for the enhancement of vegetative establishment; as long-term, nondegradable materials to extend the erosion control limits of vegetation or soil; as primary slope or channel linings; and as components in silt fences and turbidity curtains and an ever-growing array of sediment retention devices. This ever-expanding use has led to industry-wide initiatives to promote the correct specification and use of geosynthetics in erosion and sediment control, along with efforts to facilitate more comprehensive quality systems in manufacturing and better measurements of performance via new and better test methods.
