Performance analysis of reinforced vegetative channel lining systems

Rolled Erosion Control Products (RECPs) have proven to be successful in rei nforcing vegetative channel lining systems and improving their performance in Erosion and Sediment Transport Control (ESTC). Laboratory experiments an d numerical simulation performed in the present study have provided a signi ficant step towards: (1) identification of critical processes and effective mechanisms through which RECPs control and reduce erosion and sediment tra nsport; (2) identification of influential index physical, mechanical and hy draulic properties of RECPs with respect to their ESTC performance; (3) inv estigation of the applicability of existing hydraulic models of turbulent s hear flows over wavy, permeable and moveable boundaries to predict the kine matics and dynamics of flow in open-channels lined with RECPs; and (4) modi fication of the design approach for RECPs, in light of the new findings in this study.
