2. 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

3. 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

4. SedSpec BMP Introduction Provides information about construction and maintenance Experience reports

6. Rational Method Estimates peak rate of runoff Simple, widely used Requires land use, soil, flow length, slope
