Erosion

Reclamation

Water & Earth Technologies, Inc. (WET) specializes in designing plans to control surface runoff and erosion. We use erosion and sediment control models, including RUSLE and SEDCAD, to design these plans and to demonstrate their effectiveness. Our Team 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 implementation and effectiveness of Best Management Practices (BMPs).

BMP Categories

runoff/run-on collection
soil stabilization
slope stabilization
seeding and revegetation
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 at the mine, and to track BMP effectiveness trends. This information has proven to be extremely useful in developing and adjusting BMP application and use in subsequent mining and reclamation activities.
