ABSTRACT

Erosion control is one of the biggest challenges for soil conservation in rivers, channels, agriculture and infrastructure. Soil erosion is a natural process, however accelerated erosion can occur when human activities create disequilibrium in the environment. Soil erosion can cause several problems including decreases in agricultural productivity and eutrophication of waterways. Soil erosion often causes damage to civil infrastructure and accelerates desertification and sedimentation. Among the existing solutions for erosion control, geosynthetics serve as an effective and economical options. High performance Rolled Erosion Control Products (RECPs) are designed for critical erosion control applications in high flow velocity channels, stream banks, and on steep slopes. Double-twist wire mesh can be incorporated within the filaments of geomats during production, enhancing their performance against erosion and providing additional reinforcement. Incorporating double twisted wire mesh into the geomat increases resistance to shear forces, high velocity flow, extended UV exposure, and heavy traffic loading. This product is flexible and easy to install, and it gives a strong protection against erosion while promoting vegetation growth. This paper presents properties, applications and case histories of the geomat with double twisted wire mesh reinforcement.
