16. Large-Scale Channel Erosion Tested
(ASTM D 6460)
• Non-vegetated over sandy loam
• 30% Slope
• Achieved 24+ psf (shear) & 19+
ft./sec (velocity)
• Both are “+” because ½ inch
of soil loss was never
achieved. TRI Environmental
Testing facility maxed out it’s
capabilities without Flexamat
allowing any erosion to take
place!
