“…Bioengineering techniques take advantage of the natural properties of plants to stabilise the bank with the combined effects of roots and canopy cover [Gyssels et al, 2005]. These actually very old techniques [Evette et al, 2009;Anstead et al, 2012] present many advantages: they are low-cost treatment [Watson et al, 1997], they have a small carbon footprint compared to riprap [Von Der Thannen et al, 2017], they support biodiversity and ecological functions in the riparian aquatic and terrestrial habitats created [Anstead and Boar, 2010;Cavaillé et al, 2013;Evette et al, 2013;Cavaillé et al, 2018], they can increase the resilience of riverbanks against the effects of climate change [Anstead et al, 2012;Lavaine et al, 2015], and overall, they can resist very aggressive flow conditions: for instance, fascines were observed to resist shear stress up to 250 N/m² [Lachat, 1994;Gerstgraser, 2000]. These qualities make them an ideal candidate for the restoration of low-cost rivers in remote areas [Tamrakar, 2010;Dhital et al, 2013;Tamrakar et al, 2014;Dhital and Tang, 2015] or in highly urbanized areas where green solutions are welcome [Ng et al, 2011;Zhang and Chan, 2012;Zhu and Zhang, 2015].…”
