“…Values of root tensile strength decrease with increasing root diameters as studied by many other authors and can be well described by power law equation (Mattia et al, 2005;Tosi, 2007;Abdi et al, 2010b;Burylo et al, 2011). In the power law equation, the parameters depend on the plant species and environmental conditions.…”

“…The fitting curve between tensile strength and root diameter also showed that there is a power law correlation between root tensile strength and root diameter with the highest R square (Operstein and Frydman, 2000;Mattia et al, 2005;Abdi et al, 2010a) and lowest standard error (Abdi et al 2010a). …”

“…Therefore, according to the results of De Baets et al (2008); Mattia et al (2005) andOperstein and Frydman (2000) showed that for the same species in different habitats, Tr-diameter results were different. Furthermore the results of Nilaweera and Nutalaya (1999) compare with the present study showed that for different species in the same habitats also the root tensile results are different.…”

“…As Nilaweera (1994) mentioned, the value of ߙ is between 29.1 and 87.0 and for ߚthe range is between -0.8 and -0.4, which is in agreement with this result.These differences imply that more studies should be conducted about the different species in different environmental conditions to gain more species model. In the research were conducted by De Baets et al (2008), they investigated the tensile strength of some of species similar to the species considered in the study conducted by Operstein and Frydman (2000); Mattia et al (2005). Surprisingly, the results showed that the strength-diameter relationship was different between the same species in different habitats.…”

The purpose of this study is to complement the existing body of knowledge on the root system of tropical plants and their contribution to slope stability. For this reason, four trees of Acacia mangium selected as randomly in rainforest along East-West Highway, Malaysia. Root area ratio (RAR) and tensile strength (Tr) data were collected and analyzed. RAR data were measured with the whole root system and Tr were measured by individual roots. The results showed that there is a power law equation between root diameter and Tr, with an average of 44.11 Mpa (in average root diameter of 0.9mm). There was a wide variation in the RAR in relation to soil depth. Generally, RAR reduced with the increasing soil depth. Similarly, additional cohesion by plant roots conducted by Tr and RAR. In conclusion, in order to assess soil reinforcement by vegetation roots, root distribution and tensile strength data with soil depth in different vegetation and sites is necessary.

“…Riche en protéines brutes, elle constitue une source importante pour le cheptel en matière azotée, essentiellement en période de disette (Abbad & Benchaabane, 2004). Dotée d'une biomasse aérienne et racinaire assez importante, elle constitue un outil efficace et relativement peu coûteux dans la lutte contre l'érosion et la désertification et dans la réhabilitation des terres salés (Mattia et al, 2005). Ces caracté-ristiques font d'Atriplex halimus une excellente espèce pour la réhabilitation des zones dégradées pastorales.…”

Simulating vegetation controls on hurricane‐induced shallow landslides with a distributed ecohydrological model

et al. 2015

The spatial distribution of shallow landslides in steep forested mountains is strongly controlled by aboveground and belowground biomass, including the distribution of root cohesion. While remote sensing of aboveground canopy properties is relatively advanced, estimating the spatial distribution of root cohesion at the forest landscape scale remains challenging. We utilize canopy height information estimated using lidar (light detecting and ranging) technology as a tool to produce a spatially distributed root cohesion model for landslide hazard prediction. We characterize spatial patterns of total belowground biomass based on the empirically derived allometric relationship developed from soil pit measurements in the Coweeta Hydrologic Laboratory, North Carolina. The vertical distribution of roots and tensile strength were sampled at soil pits allowing us to directly relate canopy height to root cohesion and use this model within a distributed ecohydrological modeling framework, providing transient estimates of runoff, subsurface flow, soil moisture, and pore pressures. We tested our model in mountainous southern Appalachian catchments that experienced a number of landslides during the 2004 hurricane season. Slope stability estimates under the assumption of spatially uniform root cohesion significantly underpredicted both the total number of landslides and the number of "false positives," unfailed areas of the landscape that were predicted to fail. When we incorporate spatially distributed root cohesion, the accuracy of the slope stability forecast improves dramatically. With the growing availability of lidar data that can be used to infer belowground information, these methods may provide a wider utility for improving landslide hazard prediction and forecasting.
