Results of simulation revealed that the main effects of slope gradient and geotextile on the different parameters investigated were found to be highly significant. Regardless of the intensity of rainfall applied, significantly higher sediment concentration, sediment yield and soil erosion were observed at slope gradient of 35 degrees. Except for sediment yield, lowest sediment concentration and soil erosion were noted at the lowest slope gradient of 10 degrees. On the other hand, the different geotextiles used as ground cover greatly affected all the parameters being evaluated. Irrespective...
