摘要

In this study, runoff erosion control performance of different coir and jute geomeshes is studied at different slope angle, rainfall intensity, and soil-infiltration conditions using a runoff erosion control tester (based on ASTM D 7101). It is observed that the erosion control percentage under soil-infiltration conditions is lower at higher slope angle and rainfall intensity, due to the higher water flow velocity, and because of the same reason runoff volume under zero-infiltration conditions is higher. It is also observed that the geomeshes with higher weight per unit area results in lower runoff and higher culmination, due to the higher storage volume and restriction offered by larger diameter weft yarn of higher weight geomesh.
