for bare and for root-permeated topsoil samples with predicted erosion rates under the same flow conditions using the erosion equation of EUROSEM. Through backwards calculation, transport capacity efficiencies and corresponding soil cohesion values can
be assessed for bare and root-permeated topsoils respectively. A scenario analysis shows that the contribution of roots to soil cohesion is very important for preventing soil loss and reducing runoff volume.
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
