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
