“…Afterwards the discharge, Q, was estimated by the velocity -area method, which was derived from Q = VA, where, V is the measured average velocity and A, being the cross sectional area. Then Manning's roughness, n, in Tables 3 and 4 were calculated using Manning's equation (6), which, although developed for conditions of uniform flow in open channels, may give an adequate estimate of the non-uniform flow which is usual in natural channels. The Manning equation states that:…”

“…What was thought successful in the past is being reevaluated in context of impacts resulting from excessive and rapid urbanization, and public awareness of these new environmental issues. Increasing failures of traditional channelization and armoring techniques are generating questions as to whether traditional practices are appropriate in every setting [6]. The interest in natural techniques called biotechnical engineering was raised, and the benefits and advantages of biotechnical engineering were gradually reexamined [7].…”

Abstract. This study focuses on employing channel lining materials that includes Turf Reinforcements Mat (TRM) and Erosion Control Blanket (ECB) as bioengineering techniques for erosion control. Hydraulic characteristics of flow through these materials were determined in terms of flow velocities and shear stresses. The experimental results indicated that the average velocity for TRM ranges between 0.6 to 3.5 m/s, while that of ECB varies from 0.7 to 4.1 m/s. Also, TRM has shear stress values of 1.950 N/m 3 for bed and 1.575 N/m 3 for bank respectively of test channel when the flow depth was 15cm. While ECB has shear stresses of 2.138 N/m3 for bed and 1.721 N/m 3 for bank for same flow depth of 15cm. However, when the flow depth is 5 cm, TRM has values of 0.972 N/m 3 for bed and 0.769 N/m 3 for bank, and ECB gives 0.957 N/m 3 for bed and 0.766 N/m 3 for bank of test channel. Hence, the greater the flow depth, the higher the velocities and shear stresses respectively. Conversely, lower flow depths lead to velocities and shear stresses that are within the allowable standards for designing a stable channel. Generally, TRM performed the best for having higher shear stresses compared to ECB.

“…An alternate approach is to restore more naturalized instream flow patterns to allow recovery through natural recruitment and growth processes (Molles et al, 1998;Richter & Richter, 2000;Rood et al, 2003). According to Li & Eddleman (2002), traditional engineering methods for streambank stabilization that were once thought successful in the past are being re-evaluated in context of impacts resulting from excessive and rapid urbanization, and from the public awareness of these new environmental issues. These restoration strategies are very costly, may require perpetual effort, and often fail.…”

“…In fact, the development of trees is also to be avoided in order to maintain access for towing and other riverbank activities (Evette et al, 2009). Soil bioengineering techniques to stabilize streambanks and shorelines are as effective, and sometimes more effective, than traditional engineering treatments (Li & Eddleman, 2002). Techniques to stabilize streambanks work by either reducing the force of the flowing water, by increasing the resistance of the bank to erosional forces, or by a combination of the two.…”

“…Live staking, live fascines, brush layers, and branchpacking have been current listed as soil bioengineering techniques that use stems or branch parts of living plants as initial and primary soil reinforcing and stabilizing material. Based in Li & Eddleman, (2002) and USDA-NRCS (2007), we listed some of the most important biotechnical streambank stabilization techniques in Table 4. Fig.…”

This study proposes a new methodology for estimating the additional shear strength (or cohesion) exerted by vegetation roots on slope stability analysis within a coupled hydrological‐stability model. The mechanical root cohesion is estimated within a Fiber Bundle Model framework that allows for the evaluation of the root strength as a function of stress‐strain relationships of populations of fibers. The use of such model requires the knowledge of the root architecture. A branching topology model based on Leonardo's rule is developed, providing an estimation of the amount of roots and the distribution of diameters with depth. The proposed methodology has been implemented into an existing distributed hydrological‐stability model able to simulate the dynamics of factor of safety as a function of soil moisture dynamics. The model also accounts for the hydrological effects of vegetation, which reduces soil water content via root water uptake, thus increasing the stability. The entire methodology has been tested in a synthetic hillslope with two configurations of vegetation type, i.e., trees and shrubs, which have been compared to a configuration without vegetation. The vegetation has been characterized using roots data of two mediterranean plant species. The results demonstrate the capabilities of the topological model in accurately reproducing the observed root structure of the analyzed species. For the environmental setting modeled, the effects of root uptake might be more significant than the mechanical reinforcement; the additional resistance depends strictly on the vegetation root depth. Finally, for the simulated climatic environment, landslides are seasonal, in agreement with past observations.
