Landslides are widespread in many hilly and mountainous areas of the world and play a key role in the evolution of the landscape. Several studies demonstrate that human induced land cover changes, such as deforestation or afforestation, are known to have a large influence on slope stability. Newly developed highly sophisticated physically based modelling methods exist to simulate the impact of changing environmental conditions on slope stability. However, the applicability and reliability of such modelling results is usually hampered by the availability of crucial spatial input data of required quantity and highest quality. This project strives to counter this much discussed weaknesses of physically based models and the consequent results.
The main objective of this research is to investigate, quantify and assess the spatial and temporal hydrological and geomechanical effects of biomass and biomass related parameters on landslide triggering and activity. The innovative approach will be developed and tested for a study area located in the federal state of Vorarlberg, where landsliding represents a prevalent geomorphic phenomenon and high resolution multi temporal ALS (airborne laser scanning) data exist.
