Promoting Climate Resilient Rural Infrastructure in Northern Vietnam: Final Workshop - Overview of the TA 8102-VIE outputs and introduction to working session

530 views

Published on

The ADB Capacity Development Technical Assistance project Promoting Climate Resilient Rural Infrastructure in Northern Vietnam is demonstrating how non-conventional engineering solutions can strengthen rural infrastructure, resisting the hazards associated with climate change and providing opportunities to enhance community livelihoods. The project focuses on bioengineering as a low-cost alternative to conventional slope stabilization and protection techniques

  12. 12. TR-17: Technical Guidelines for Slope Protection Concise guidance to the selection of appropriate bio-engineering and associated engineering options for the surface protection of inland roadside and riverside slopes. This guidance is aimed primarily at the rural infrastructure but its principles may be adapted for use in other slope protection environments.
  13. 13. General Description Fascines are linear bundles of live hardwood cuttings tied together and laid in shallow trenches with wooden stakes across a slope and used to catch slope debris, and to armour, and reinforce the slope. After burial in trench they put out rots and shoots, forming a strong line of vegetation. Maximum slope about 45°. The option provides immediate and increasingly strong protection and reinforcement through the development of roots and subsequent plant growth. Key Design and Resource Requirements  Long straight flexible branches (1.5-2m long by 20-25mm diameter) tied in bundles 150-300mm in diameter laid in shallow trenches across the slope. Tips and basal ends should be evenly distributed through bundles.  Design input should include slope angles, soil type and depth as well a grading, pH, soil chemistry.  Planting should be by experienced agricultural labour with general supervision. Principal Uses and Advantages  A useful method of rapid vegetation establishment on slopes on roadside and riverbank slopes. Act as a scour check; if undermined they can bridge gap and still thrive. Can be installed before busy rainy season. Shoots more vigorous than palisades or cuttings. When cut from appropriate species and properly installed with live and dead stout stakes, fascines will root and immediately begin to stabilise slope surfaces. They may place an angle on wet slopes to induce drainage.  Fascines are used to provide erosion and sedimentation control by increasing infiltration, slowing run-off and trapping seed and sediment. They can protect slopes from shallow slides (0.3-0.5m depth), Capable of trapping and holding soil on the face of the slope, thus reducing a long slope into a series of shorter slopes. Principal Concerns Stabilisation of shallow instability only. For live fascines to function properly, it is vital that they develop proper growth. Best if bundles can be installed on day of harvest. Require a large amount of cutting materials. May encourage infiltration and saturation of surface and lead to shallow sliding in soft or weak materials. Not suitable on soft or loose materials.
