Efficacy of Jute Geotextiles (JGT) in hill slope management stands substantiated as a result of its unique attributes such as its bio-degradability, hydrophilic properties, and ability to moderate temperature extremes have few parallels among ecofriendly natural fibres. The mechanism of containment of top soil erosion is the resultant effect of velocity of surface run-off propelled by gravity, ground friction, hydraulic conductivity of the slope fill, absorption of a portion of run-off by jute yarns of open weave JGT, and barrier effect posed by them on the other. JGT also acts as mulch creating a microclimate that fosters quick growth of vegetation on biodegradation. JGT plays an important role in bioremediation of slope-erosion problems. The paper delineates climatic factors, types of JGT used, and the prevailing site conditions of various trial sites, with an attempt to analyze the mechanism of functioning of JGT in low temperature zones.
