Abstract | The learning unit introduces erosion and instability phenomena on hill-slopes and slopes, evaluating options and constraints of protective effects of organisms against those phenomena. Next, the LU explores the translation of protection requirements into soilbioengineering solutions, and analyses their effectiveness, and their effects on the natural and social environment. |
Learning objective | Understand erosion and mass movement processes on slopes and embankments. Understand possibilities and limitations of the soil retaining and stabilization effects of organisms. Transform erosion and instability control re-quirements into geotechnical/biological concepts (Solution definition process). Analyses of the solution with regard to functional requirements, biological effects, and impacts on the physical and social environment (System Analysis process). |
Content | Erosion and instability phenomena on slopes and embankments. Approaches to influence erosion and instability processes. Effect of vegetation cover. Methods of soil bioengineering. Selection and procurement of plant materials. Engineering methodology (Problem definition, hazard, scenarios, safety plan, solution concept, analysis and evalua-tion. Basics of construction techniques, maintenance and rehabilitation. Case studies. |
