Landfill final covers and soil loss from water erosion
- HDR Engineering, Dallas, TX (United States)
Federal Subtitle D rules require that landfill final covers be designed so as to {open_quotes}minimize erosion{close_quotes} and {open_quotes}be capable of sustaining native plant growth.{close_quotes} The Universal Soil Loss Equation (USLE) has been recommended by the EPA as the most appropriate means for evaluating the suitability of landfill final cover designs with regard to soil loss from water erosion. Since the introduction of the original USLE, two predictive tools have been introduced that are more appropriate for determining soil loss from water erosion. The Revised Universal Soil Loss Equation (RUSLE) model, the intermediate product of erosion research since the development of the original USLE, and the Water Erosion Prediction Program (WEPP) are presented. These models are improved estimating tools that better account for landfill final cover design variables such as slope length, steepness, and non-agricultural cropping and management scenarios than the outdated USLE. The regulatory premise for requiring erosion design and erosion control planning for landfill final cover systems and their practical implementation is also discussed.
