Description :
In this study, the effectiveness of 3 biological geotextiles in reducing soil losses during concentrated flow is investigated. Runoff was simulated in a concentrated flow flume, filled with an erodible sandy loam on 3 slope gradients. Treatments included 3 biological geotextiles (borassus, buriti and bamboo) and one bare soil surface. The highest resistance against soil detachment was observed for the borassus covered soil surfaces. Overall, biological geotextiles are less effective in controlling concentrated flow erosion compared with interrill erosion.
