“…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].…”

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.

“…The first way is to reduce the runoff generation of the slope to minimize the runoff's erosive force. The second way is to increase the soil's reinforcement capacity on the slope and to reduce the supply of materials to the slope [17][18][19][20]. Combined with the runoff characteristics above, we can see that the W-OH solution is mainly used to improve the slope's soil reinforcement capacity.…”

Ecological restoration is difficult on the red clay highway slopes in the rainy areas in South China that experience severe soil erosion. By using the hydrophilic polyurethane material W-OH to solidify and protect red clay slopes, the erosion control will be substantially improved. We employed simulated rainfall erosion experiments and pot experiments to evaluate the anti-corrosion and growth promotion performances. We found that, (1) in the initial stage of protection, W-OH had the effect of accelerating slope drainage, solidifying the soil structure, and reducing soil loss, with the sediment reduction benefit reaching 37.4–65.3%. (2) The anti-erosion effect was mainly based on soil solidification. (3) The W-OH was affected by rainfall intensity and the W-OH concentration, and the soil erosion prediction equation was constructed according to the observation. (4) W-OH had a promising water retention performance and can promote the germination and late growth of slope plants to reduce the influence of eluviation. (5) The suitable W-OH solution concentration was 3–5% for slope protection herbs and shrubs, which were commonly used in South China. (6) The reduction in porosity was the fundamental cause of water retention improvement. The ecological restoration of slopes is a comprehensive process. Therefore, both anti-erosion performance and later plant growth are necessary. Our research provides a theoretical and experimental basis for applying the W-OH in the ecological restoration of the red clay slopes in subtropical areas and expanding the scope of the W-OH.

La ingeniería de ríos ha proporcionado los elementos teóricos, empíricos y prácticos para intervenir en los cursos fluviales con la finalidad de aprovechar los recursos hídricos o de reducir los riesgos de daño a poblaciones e infraestructuras. Tradicionalmente, el ingeniero hidráulico con especialidad en ingeniería de ríos ha emprendido estas acciones mediante soluciones que se pueden denominar como “rígidas” o “duras”, por los materiales y las técnicas constructivas empleadas, pero también por la filosofía subyacente, que favorece las actuaciones sobre los efectos visibles, antes que sobre las causas. Sin embargo, en las últimas décadas nuestras sociedades han experimentado un cambio en su percepción y relación con el ambiente, el cual propugna como valores fundamentales el buen estado de los ecosistemas acuáticos y una gestión sostenible de los recursos hídricos. Este cambio de paradigma implica una profunda revisión del papel del ingeniero de ríos en la planificación, intervención y gestión de los espacios fluviales, asumiendo un giro sustancial en el enfoque de las actuaciones, así como la necesidad de colaboración estrecha con profesionales de diversas disciplinas. En este trabajo se discute el nuevo papel del ingeniero de ríos y los retos a los que ha de hacer frente en las sociedades latinoamericanas. En particular se hace énfasis en la singularidad ambiental y social de la región, que requiere del ingeniero de ríos nuevas competencias técnicas, pero también compromiso ambiental y social, así como una participación activa como enlace entre expertos de diversa índole, la sociedad y las autoridades.
