| Popis: | Geomeshes made up of coir fibers are a possible great alternative before vegetation establishes itself, and provides immediate soil erosion control on different types of slopes. In this study, coir geomeshes structure has been modified for better erosion over different soils. Different structurally modified coir geomeshes are tested for runoff erosion control, culmination discharge over loamy sand, silt loam, and silty clay loam soil at different slope angles. Lowest erosion control is observed over loamy sand due to higher amount of sand percentage. To know the overall effect of geomeshes, germination tests are also performed. It is observed that twill weave of coir geomeshes provides better erosion control due to the higher float length at the backside which reduces the water velocity. Twill weave geomeshes also provide better germination than plain and satin woven geomeshes. Overall, twill weave geomesh is preferred over loamy sand, silt loam, and silty clay loam at lower and medium slope angles. |
