“…First, the size of woody vegetation ranges from twigs (slender terminal branches) and saplings to mature trees. The size influences the biomechanical characteristics of plants [e.g., Sutili et al ., ], but a model representation allowing the same parameter values to be used for vegetation of different sizes would be desirable. Second, the key factors governing the flow resistance depend on the scale of investigation, which varies from plant stands to single foliated specimens or leafless stems, foliage, and individual leaves.…”

Modeling the flow resistance of woody vegetation using physically based properties of the foliage and stem

[1] Both the foliage and stem essentially influence the flow resistance of woody plants, but their different biomechanical properties complicate the parameterization of foliated vegetation for modeling. This paper investigates whether modeling of flow resistance caused by natural woody vegetation can be improved using explicit description of both the foliage and stem. For this purpose, we directly measured the drag forces of Alnus glutinosa, Betula pendula, Salix viminalis, and Salix x rubens twigs in a laboratory flume at four foliation levels, parameterized with the leaf-area-to-stem-area ratio A L /A S . The species differed in the foliage drag but had approximately equal stem drag. For the foliated twigs, increasing A L /A S was found to increase the reconfiguration and the share of the foliage drag to the total drag. The experiments provided new insight into the factors governing the flow resistance of natural woody vegetation and allowed us to develop a model for estimating the vegetative friction factor using the linear superposition of the foliage and stem drag. The model is novel in that the foliage and stem are separately described with physically based parameters: drag coefficients, reconfiguration parameters, and leaf area and frontalprojected stem area per ground area. The model could satisfactorily predict the flow resistance of twig to sapling-sized specimens of the investigated species at velocities of 0.05-1 m/s. As a further benefit, the model allows exploring the variability in drag and reconfiguration associated with differing abundance of the foliage in relation to the stem.Citation: V€ astil€ a, K., and J.

“…This research efforts are showing important results that change consolidated perspectives in fields such as the hydraulic behavior of plants (e.g., Sutili, Denardi, Durlo, Rauch, & Weissteiner, ; Weissteiner et al, ), but are also stressing the need for further approaches to the use of vegetation as an important contribute to the regulation of natural processes such as the retention of superficial runoff, that can be an important contribution for hydrological regulation and erosion prevention and correspondent hydrological services.…”

This paper analyzes the concept of nature‐based solutions as instruments to turn anthromes more nature compatible, efficient, causing less degradation, and developing new biodiversity hotspots. It is mainly focused on solutions using living organisms (in particular plants and microorganisms) to perform functions such as those of soil‐ and water‐bioengineering interventions in order to ensure the safety of human infrastructures and constructions in contexts of conflict between natural processes and human needs. Further, it handles the problematic of reintroducing natural processes and functions in the built environment (urban, industrial, infrastructures, etc.) in order to recover, recreate, or reinvent nature in humanized landscapes and developing a more creative relation between humans and natural elements, processes, and functions. It presents, furthermore, the contribution of natural solutions to a wide variety of decontamination processes and prevention and recovery of degraded land and natural resources. Finally, we discuss the way these solutions can be implemented and the cultural, organizational, administrative and governance, paradigmatic, and practice changes it implies. Examples are given on the different issues presented as well on the possible implementation solutions.

“…The G. schottiana species has already been successfully used in SWBE studies in Southern Brazil (Durlo and Sutili, 2014;Kettenhuber et al, 2017;Maxwald et al, 2020), especially for streambank stabilization, due to its functional traits and will therefore be used in this study as a reference species. This species is classified by (Marchiori, 2000) as a hygrophilous species, having flexible branches that are very resistant to breakage (Sutili et al, 2012) and good resistance to uprooting (Dewes et al, 2019), which makes it able to resist the force of water during floods and suitable for protecting and stabilizing streambanks. This type of propagation enables using native local or regional species harvested from surrounding areas of the intervention site which are more adapted to the local edaphoclimatic conditions, and the production of a large number of seedlings in a shorter time and with reduced costs (Kettenhuber et al, 2019;Díaz-Páez et al, 2021).…”

Soil and water bioengineering (SWBE) is a feasible, economical and ecologically friendly alternative to restore the riparian forest areas affected by the Brumadinho mining tailings dam rupture. We evaluated the vegetative propagation capacity by cuttings and initial development of nine native riparian species of the Paraobepa River for use in SWBE techniques. From the results it is possible to separate the species into two distinct groups, namely those that can resprout and produce roots from their cuttings (group 1: Acnistus arborescens (L.) Schltdl., Croton urucurana Baill., Gymnanthes schottiana Müll.Arg., Indigofera suffruticosa Mill. and Sesbania virgata (Cav.) Poir.) and are suitable for use as live cuttings in SWBE techniques; and those which were only able to produce shoots (group 2: Casearia decandra Jacq., Chrysophyllum marginatum (Hook. & Arn.) Radlk., Inga vera Willd. and Schinus terebinthifolia Raddi) and should only be used in seedling form to increase the diversity of the interventions.
