“…The use of NBS techniques has become popular in several areas of Europe, China, and North America [28,29], and more recently also in developing countries [26,27,[30][31][32]. Indeed, the use of organic and biodegradable geotextiles for soil erosion reduction, erosion control, vegetation growth, and slope stabilization is rapidly evolving [33][34][35][36][37][38][39][40][41]. For example, Smets et al [42] demonstrated that palm geotextiles reduce runoff coefficients and mitigate soil erosion in hillslopes, while Gimenez-Morera et al [38] showed that cotton palm may limit soil erosion in Mediterranean climatic conditions.…”

Soil erosion during rainfall events is affected by several factors, such as topography, soil type, land management, and vegetation cover. In this study, a series of tests investigates the influence of selected perennial herbaceous plants with a deep and strong rooting system, called MC1, on runoff generation and soil erosion. The tests on the investigated nature-based solution have been performed in the Cape Fear experimental hillslope with natural and artificial rainfall and for different vegetation heights. For all the experiments, runoff, soil moisture, and erosion data were observed and collected. The results obtained in this study suggest the following conclusions: (1) MC1 is effective in terms of soil erosion reduction already with a minimum vegetation height equal to 30 cm; (2) MC1 maximum efficiency, in terms of soil loss reduction, has been reached for a vegetation height equal to 70 cm; (3) In terms of the eroded material, the use of MC1 allows for a reduction of soil loss up to 300 times higher than the bare soil condition; (4) The use of MC1 allows for a reduction in the runoff coefficient up to 1/3 of the corresponding value in the bare soil condition.

“…Analysis for different root architectures like without vegetation, with semi-spherical vegetation, uniform vegetation and cylindrical vegetation was done and it was observed that rooted soil showed much improved values of factor of safety and shear strength than the soil without root [6]. Roots of the vegetation can reach up to the depths of 3m [4,7,9]. The zone of Soil with roots is represented in terms of root reinforced soil properties with anchors [8,10] and only as root reinforced soil [8].…”

Vegetation plays a major role in terms of slope stability. Roots of grass and trees can increase the strength properties of soil which improves the stability of slope. A natural slope consists of grass and infinite number of trees inclined in different directions along with inclined roots. The aim of the paper is to study the effects of vegetation growth on slope stability for different root reinforced soil depth by varying tree inclination (along with roots), root spread and tree spacing for different slope geometry. The study involves determination of safety factor (FOS) of natural slope existing with and without vegetation growth (such as only grass, grass and trees). GeoStudio Slope/w software with limit equilibrium method was used for stability analysis of different slope inclinations. A tree was modelled as a point load and its roots were represented as reinforced soil properties with anchors and only as root reinforced soil. When compared to the bare slope, it was observed that there was an increase in FOS of slope on both the models of vegetation. Variations in FOS by varying root reinforced soil depth, tree inclinations and spacings were reported for different slope geometry and compared. Considering all these parameters, an empirical corelation for computation of vegetation influenced FOS has been developed. This study provides a mechanical accountability of vegetation cover on the stability of slopes.

“…Several studies in the literature have focused on assessing the effectiveness of biodegradable geotextiles for soil loss and runoff reduction. For instance, palm geotextiles have proved to reduce runoff coefficients and total soil loss in medium and steep slopes (Smets et al, 2007); cotton was showed to limit soil loss to negligible values in Mediterranean climatic conditions (Giménez-Morera et al, 2010); and hyacinth limited life geotextiles considerably reduced soil loss in laboratory conditions (Maneecharoen et al, 2013). Among biodegradable fibers, jute meets most of the technical requirements for geo-technical applications.…”

Biodegradable geotextiles have the potential to significantly reduce soil loss and ensure slope stability in areas at risk. Here, we focus on three biodegradable textiles (namely, jute net, jute mat, and wool mat), and study their response in terms of soil loss to diverse precipitation events (average rainfall intensity from 3.7 mmh−1 to 70 mmh−1 and duration from 0.5 h to 11.6 h). Experiments are conducted in an ad hoc developed outdoor steep slope (more than 60%). Soil loss reduction from the treatments is found to be very remarkable (up to 98%), thus supporting the potential of natural materials for soil conservation. Also, experimental findings confirm that the maximum intensity of rainfall events plays an important role in driving soil erosion.
