Abstract:
For hazard zoning or planning of control measures the identification of the hydrogeomorphic key process is an important step to determine the recurrent design event. The present methodology for the identification of potential hydrogeomorphic key processes is a practicable tool for experts assessing homogeneous sections of running waters (torrents, mountain streams and low-lying rivers) by means of certain parameters. Filling in the developed matrix from your desk and reviewing the results with field surveys on site, the potential key process is rapidly identified for each homogeneous area, as the evaluation of 12 sample streams in Carinthia shows. Further on this method is a useful tool concerning sediment management concepts according to the National Watercourse Development Plan or financial supporting of control measures at stakeholder waters at the field of competence of the Austrian Flood Control Management.
