Technology in Action

1st Place:
Erosion control blankets were installed to avoid sedimentation from reducing the capacity of the drainage system in Minas Gerais, Brazil.

2nd Place:
Following the Angora fire near Lake Tahoe, Calif., erosion control blankets, wattles, silt fence and mulch were deployed to prevent erosion and sediment damage.

3rd Place:
Early sproutes of vegetation are growing through a Recyclex TRM-V matrix after a rain in Rice Lake, Wis. This application was engineered for low to medium flow channels and slopes requiring permanent vegetation reinforcement. The TRM indicates fibers made from 100% recycled ?EUR??,,????'?????< Submitted by Kurt Kelsey, American Excelsior Co. Photo: Michael Nelson, Oct. 2009.

2nd Place:
Hydraulic mulch was clearly not the proper BMP for this roadside slope in Wiggins, Miss.

3rd Place:
A combination of design mistake and absence of superficial protection promoted huge gullies at this project in Minas Gerais, Brazil.

Before and After

1st Place:
Bioengineering stabilized this slope at Butter Hill in Camacari, Bahia, Brazil. Imagine this dirt street after a copious rain before vegetation took hold on the cliffs.

BEFORE

2nd Place:
Before (below): This slope in Des Moines, Iowa is pictured shortly after erosion control blankets (Curlex CL) were installed. (Above) The after image is three weeks after laying the blankets.
