Characterizing Sediment Retention Devices with ASTM Methods

By Joel Sprague and Jay Sprague – Sediment retention devices include silt fence, wattles, filter logs, compost socks, and various types of stormwater inlet protectors. They are a widely used best management practice (BMP) to remove sediment from stormwater runoff as water passes through the BMP. However, SRD performance varies greatly with regard to flow rate and filtration efficiency. The body of performance data related to the flow rate and filtration capabilities of SRD products based on recognized standard ASTM test procedures is limited but growing. Here at TRI, we regularly conduct standardized SRD tests to help private companies, project owners, and the overall field build its understanding of and confidence in the selection of sediment retention devices.

Hydropower Project Realizes Huge Savings with Reinforced Soil

The newly constructed Arkun Dam hydropower facility on the Çoruh River (Turkey) would have been considerably more expensive if conventional concrete walls were used along the edges of the power station. NAUE Geosynthetics profiles the project and the reinforced earth option that was selected and which saved 40% on the cost for this portion of the project.

Sustainable Development Goals and Geosynthetics

This April, Geosynthetica is promoting 30 Days of Earth Day (#30DaysEarthDay). Each day we will publish stories on the intersections between geosynthetics and environmental...
