DenverDownsResearchFacility

TRI/Environmental (TRI) is a leading, accredited geosynthetic, plastic pipe, and erosion and sediment control product testing laboratory. TRI’s large-scale testing facility in the upstate of South Carolina at the Denver Downs Research Farm (DDRF) currently focuses on erosion and sediment control testing and expands on our industry-leading index and bench-scale erosion and sediment control testing capabilities. DDRF is a 300+ acre research farm affording plentiful access to various sloping terrain and water from four ponds. Additionally, DDRF has numerous unused structures which are available to house covered research and testing and for material and equipment storage. Earthmoving equipment is also readily available. DDRF is located just a mile off Interstate 85 about 25 miles southeast of Greenville, in Anderson County, SC. A large selection of hotels and restaurants are available within 1 mile of the site. The facility began operating in the third quarter of 2006.

ASTM D 6459 Determination of Rolled Erosion Control Product (RECP) Performance in Protecting Hillslopes from Rainfall-Induced Erosion. This is full-scale simulated rainfall on 3:1 slopes with bare and RECP-protected soil, including:

Rainfall Intensities = 50, 100, 150 mm/hr @ 20 minutes each;
1 control + 3 replicate slopes;
Inclined (3:1) slopes, 40-ft long and 8-ft wide;
18-inch compacted soil veneer;
Simulated rain system with 14-ft drop height & up to 6+ inches/hr capacity.

ASTM D 6460 Determination of Rolled Erosion Control Product (RECP) Performance in Protecting Earthen Channels from Stormwater-Induced Erosion. This is full-scale channel flow with RECP-protected soil, including:

Increasing Shear Levels psf @ 30 minutes each;
3 replicate test sections;
Rectangular (flume) or Trapezoidal cross-section with 5 and 10% slope;
Rectangular cross-section has 2-ft width and 2-ft high side walls;
Trapezoidal cross-section has 2-ft bottom and 2H:1V side-slopes;
12-inch compacted soil veneer;
80-ft total length;
Flow capacity up to 30cfs for 30 minutes = 54000 ft³ = 13,500 gpm.

ASTM D 7208: Determination of Temporary Ditch Check Performance in Protecting Earthen Channels from Stormwater-Induced Erosion. This is full-scale channel flow (3 cfs) in a trapezoidal channel with check structure(s) installed.

ASTM D 7351: Determination of Sediment Retention Device Effectiveness in Sheet Flow Applications. This is full-scale sediment retention device (SRD) exposure to sediment laden runoff equivalent to a 100-ft long slope and a 4” rainfall.
