Soft-armor alternatives for storm water management
Northeast of Columbia (USA), in an area commonly referred to as the Sandhills, the South Carolina Department of Transportation (SCDOT) planned a widening project for the Clemson Road route. In this region, the sandy soil, three rivers, an average annual rainfall of 1.3 m, and water in the ground made the erosion of channels and ditches a serious issue. In order to preserve the natural order of the ecosystem, SCDOT decided they needed some type of turf reinforcement. The most economic and environmentally friendly choice for the project was a high performance turf reinforcement mat (HPTRM, Pyramat from SI Geosolutions Inc.). The woven, three-dimensional construction provides long-term survivability, strong geobotanical reinforcement, tensile strength and sheer stress resistance. The HPTRM serves the SCDOT's need for environmental preservation by promoting the growth of vegetation. It intertwines with the natural roots and shoots of plant life to create a stabilization matrix that keeps soil in place while allowing vegetation to flourish. Research has shown that vegetated channels can capture as much as 700 % more sediment than channels lined with hard armour. The Clemson Road project concluded successfully in 2001. The installation is still holding its ground. Erosion has not occurred, and vegetation has flourished, especially on the bottom of the ditches.
