Erosion and Sediment Control

 

 

WET specializes in designing plans to control surface runoff and erosion. We use erosion, sediment, and disturbed-land reclamation models, including SEDCAD, RUSLE and Natural Regrade, to design these plans and to demonstrate their effectiveness. WET has developed and implemented programs for disturbed and reclaimed areas to evaluate erosion potential and sediment production, stream dynamics (of both natural and altered stream channels), and the effectiveness of Best Management Practices.

BMP Categories

  • Runoff/run-on collection
  • Soil stabilization
  • Slope stabilization
  • Seeding and re-vegetation
  • Overburden handling
  • Range management
  • Sediment runoff

BMP Design

  • Terraces
  • Diversion channels
  • Check dams
  • Sediment ponds
  • Downdrains
  • Riprap
  • Silt fences
  • Grass filters
  • Culverts

We have established practical BMP implementation standards and performance effectiveness criteria for each of these categories, including methods for conducting on-site erosion inventories, BMP field inspection, and BMP performance evaluation and effectiveness ranking to numerically assess the level of effectiveness attained, and to track BMP effectiveness trends. This information has proven to be extremely useful in developing and adjusting BMP application and use in subsequent program activities
