Assessment of soil bioengineering and conventional methods used in road side slope stabilisation work in Nepal
In a mountainous developing country such as Nepal, the deforestation of steep slopes for the expansion of agrarian cultivation areas, extensive clear cutting for wood production, as well as roads, railways, artificial dams and mining activities on a large scale, are the most important anthropogeneous causes for soil erosion and landslides. With regard to sustainable technical, ecological and socio-economic strategies, the solution to these problems requires a multidisciplinary approach. For the development of infrastructure projects, various factors have to be considered and implemented by engineers and authorities in the planning and execution. Over the past 20 years, bioengineering has established itself as an alternative and complementary discipline to conventional engineering methodologies for the safety of embankments. Living plants and excipients are used as building material. From the perspective of sustainability, environmental friendliness and socioeconomics, these "living" engineer-biological systems offer many advantages, but have the disadvantage that there is still a high demand for research on the technical standardisation and dimensioning. This project aims at making a contribution to this demand in the context of a field study. The project aims are: 1. Comparison of an engineer-biological method (bamboo wall; supports the embankment body) with a conventional method (gabion) 2. Presentation of the measures carried out as a demonstration project 3. Integration of the local population into the project by means of practical work; increasing the awareness for the possibilities of application of bioengineering in Nepal 4. Design and organisation of a training programme for the application of engineer-biological measures for technicians Further information: University of Natural Resources and Applied Life Sciences, Institute of Soil Bioengineering and Landscape Construction Tribhuvan University
