SedSpec Introduction• SedSpec (a WWW-based tool) provides the
necessary calculations to provide approximate sizes and costs of hydrologic and erosion control structures• Channels (grassed, open, riprap, concrete)• Culverts• Sediment basins• Terraces• Runoff diversions• Storm water detention basins
SedSpec Introduction
• SedSpec utilizes TR 55 or the Rational Method to compute peak rates of runoff.
• Database holds rainfall depths
• User provides data in a web form
SedSpec BMP Introduction
• Provides information about construction and maintenance
• Experience reports
Rational Method
• Estimates peak rate of runoff
• Simple, widely used
• Requires land use, soil, flow length, slope
