Повний текст джерелаIt is generally accepted that tree roots can reinforce soil and improve the stability of vegetated slopes. Tree root reinforcement is also recognised in riverbanks although the contribution that the roots make to bank stability has rarely been assessed due to the reluctance of geomorphologists to examine riverbank stability by geomechanical methods that allow for the inclusion of quantified biotechnical parameters. This study investigates the interaction between alluvial soil and the roots of four southeastern Australian riparian trees. It quantifies the amount and distribution of root reinforcement present beneath typically vegetated riverbanks of the upper Nepean River, New South Wales, and examines the effect of the reinforcement on the stability of these banks. The ability of a tree to reinforce the soil is limited by the spatial distribution of its root system and the strength that the roots impart to the soil during shear. These two parameters were determined for the following four species of native riparian tree: Casuarina glauca, Eucalyptus amplifolia, Eucalyptus elata, and Acacia floribunda. The four species all exhibit a progressive reduction in the quantity of root material both with increasing depth and with increasing lateral distance from the tree stem. In the vertical direction there are two distinct zones that can be described. The first occurs from between 0 and approximately 15 % of the maximum vertical depth and consists of approximately 80 % of the total root material quantity. In this zone the root system consists of both vertical and lateral roots, the size and density of which varies between species. The second zone occurs below approximately 15 % of the maximum vertical depth and consists primarily of vertical roots. The quantity of root material in this zone decreases exponentially with depth due to the taper of individual roots. The earth reinforcement potential in terms of both geometric extent and the quantity of root material expressed as the Root Area Ratio (RAR) varies significantly from species to species. E. elata exhibited the highest values of RAR in soil zones beneath it while E. amplifolia reinforced a greater volume of soil than any of the other species examined. The increased shear resistance (Sr) of alluvial soil containing roots was measured by direct in-situ shear tests on soil blocks beneath a plantation. For three of the species (C. glauca, E. amplifolia, E. elata) Sr increased with increasing RAR measured at the shear plane, in a similar linear relationship. The shear resistance provided by A. floribunda roots also increased with increasing RAR at the shear plane but at a much greater rate than for the other three species. This is attributable to A. floribunda’s greater root tensile strength and therefore pull-out resistance, as well as its smaller root diameters at comparative RARs which resulted in a greater proportion of roots reaching full tensile strength within the confines of the test. Tree roots fail progressively in this system. Therefore determining the increased shear strength from the sum of the pull-out or tensile strengths of all individual roots and Waldron’s (1977) and Wu et al’s (1979) simple root model, would result in substantial over estimates of the overall strength of the soil-root system. The average difference between Sr calculated in this manner and that measured from direct in-situ shear tests is 10.9 kPa for C. glauca, 19.0 kPa for E. amplifolia, 19.3 kPa for E. elata, and 8.8 kPa for A. floribunda. A riverbank stability analysis incorporating the root reinforcement effect was conducted using a predictive model of the spatial distribution of root reinforcement beneath riparian trees within the study area. The model is based on measurements of juveniles and observations of the rooting habits of mature trees. It indicates that while the presence of vegetation on riverbank profiles has the potential to increase stability by up to 105 %, the relative increase depends heavily on the actual vegetation type, density, and location on the bank profile. Of the species examined in this study the greatest potential for improved riverbank stability is provided by E. amplifolia, followed by E. elata, A. floribunda, and C. glauca. The presence of trees on banks of the Nepean River has the potential to raise the critical factor of safety (FoS) from a value that is very unstable (0.85) to significantly above 1.00 even when the banks are completely saturated and subject to rapid draw-down. It is likely then that the period of intense bank instability observed within this environment between 1947 and 1992 would not have taken place had the riparian vegetation not been cleared prior to the onset of wetter climatic conditions. Typical ‘present-day’ profiles are critically to marginally stable. The introduction of vegetation could improve stability by raising the FoS up to 1.68 however the selection of revegetation species is crucial. With the placement of a large growing Eucalypt at a suitable spacing (around 3-5 m) the choice of smaller understorey trees and shrubs is less important. The effect of riparian vegetation on bank stability has important implications for channel morphological change. This study quantifies the mechanical earth reinforcing effect of some native riparian trees, thus allowing for improved deterministic assessment of historical channel change and an improved basis for future riverine management.

In this study, a movable bed flume was set up. To make the conditions close to the natural rivers, the channel bank was paved with the cohesive material composed of the mixture of silica sand and kaolinite; the channel bed was paved with the noncohesive material of the silica sand. Several experimental cases with various inflows and angles of channel bank were conducted to investigate the influence of bed scouring to the time and distance of bank collapsing. Moreover, this study adopted a 2D Depth-Averaged Model (Hsieh, 2003) with adding bank scouring formula for cohesive material(Arulanandan et al., 1980) and safety factor of cantilever failure formula (Chiang, 2011) to simulate experiment cases. The simulation results were analyzed and compared with measured data.

This study aims at employing a flume experiment to analyze the influence of river-stage effect on riverbank stability. Mass failure model developed by Chiang et al. (2011) is applied to verify the experimental results. In the beginning, three dimensionless parameters for this flume experiment are derived by dimensional analysis. To ensure the repeatability, a pretest is undergone to examine designed experimental procedure. The mixture of silica sand and kaolinite is selected as experimental bank material, and is measured by sieve analysis and direct shear and permeability test. Essential terms like initial river stage, drawdown speed of river stage, and angle of river bank have been acquired in the designed experiment for analyzing their effects on riverbank stability. Due to the need of cross examination, the above-mentioned model is used to calculate pore water pressure and safety factor of riverbank. Finally, it is confirmed that flume experiment outcomes show good agreement with the result from numerical simulation.

In this study, a model combining Green-Ampt infiltration theory with Boussinesq equation has been developed to simulate groundwater table variation under the condition of interactions between rainfall infiltration and variation of river stage. Depending on the calculated groundwater table, pore-water pressure can be estimated with the assumption of hydrostatic pressure distribution. Subsequently, riverbank stability can be assessed by factor of safety based on limit equilibrium method. The developed model was used to examine the effects of key parameters including various values of soil permeability, rainfall intensity and changing speed of river stage on the riverbank stability. In addition, Cho-Shui Creek during Typhoon Krosa occurred in 2007 was chosen as an application case. According to the simulated results, the riverbank failure is easily to be triggered with high permeability soil under heavy rainfall intensity or with low permeability soil under rapid drawdown.

Due to the global environmental discredits and increasing concerns of ecological conservation, civil work must do more improvements in order to meet the environmental landscape requirements. Especially, the environment impact assessment surveys and investigations must be taken care of in any large development projects and adopted by bioengineering conservations and restoration methods whenever possible. River management should be built by using life plant instead of inanimate concreted structure. Creating a construction is a harmonious project among landscape, ecology, and safety. It should minimize the interruption of artificial and input of exterior energy in order to maintain the system in a steady status. Utilizing both plants’ special characteristics and ecosystem self-organized behaviors to riverbed stability and riverbank protection, and using the suitable techniques under certain limited conditions at right time can provide the best efficiency in bioengineering. In the mean time, it also can solve the trouble of dying rivers facing today — using reinforcement concrete materials in rivers’ structures. Because of lacking information for riverbank stability and planting effectiveness, designers usually have no intention to use bioengineering in their designs. The major goal of this research is to promote and encourage all hydraulic engineering designers to use them in Taiwan, which have been proved by many overseas projects and local flood attacked. It would be very valuable by implementing these successful experiences as a guideline for the future works.
