Investigating alpine grass patches for their susceptibility to erosion
Abstract
General: Alpine areas above the timberline which are grazed or exploited for tourism purposes frequently show little or no superficial signs of erosion. But heavy rainfall may nevertheless cause erosion damage of large sheets of land. Methodology: A survey of the vegetation aims to determine whether the vegetation cover shows signs of slope instability. This offers an opportunity to test SCHAUER's hypothesis (1975, 1996) that a uniform root layer is the main cause of soil erosion.The second stage investigates whether a scientific analysis of the field soil can help determine the risk of erosion. This work is based on DOMMERMUTH's hypothesis (1996) that certain soil parameters are indicators of erosion risk.The third stage is an evaluation of soil bioengineering measures taken for future and improved erosion protection.The analyses are made in the Sellrain valley and Karwendel mountains in Tyrol, in the Meran 2000 erosion area in South Tyrol, along the Grossglockner Mountain Road in Carinthia, along the Felbertauern Road (Salzburg/Tyrol) and at the Galina stream in Vorarlberg. The object of the research project is to develop a quick and simple test to determine susceptibility to erosion of a given area by surveying the vegetation and soil.
