THE „GESCHIEBEPOTENTIALBAND“ – A TOOL FOR A CONCISE DOCUMENTATION AND DATA STORAGE OF THE PARAMETERS
OF A TORRENT
Michael Mölk1 IntroductionAs a part of the ETAlp-project of the Austrian Service for Torrent and Avalanche Control a standard for the documentation of torrents was developed. With the so called
“Geschiebepotentialband” all relevant parameters of a torrent are to be represented in a graphic solution including a longitudinal section of the torrent. Besides the geometrical parameters necessary for the positioning of the documented parameters, all other input is optional and can be skipped if not considered relevant.
Description of the tool
In addition to the geometrical parameters of the torrent (longitudinal inclination, length of respective section, geometry of cross sections – figure 1) the following parameters can be integrated in the documentation:
Geology (riverbed, slopes, joints, bedding planes ...)
Characteristics of the riverbed (roughness, thickness of bed-fillings, geometry, grain size distribution …)
Existing mitigation measures (type and position) Potential for jamming logs
Indications for debris flow potential (assessment of deposits, debris-flow erosion …) Actual and potential jamming sites
Assessment of tributaries (including their debris-potential)
Debris-potential of slopes (including: disposition in classes, via the input of measurements the volume of the potential mobilisation is calculated automatically) Potential bedload derived from material deposited in the riverbed

To produce an easy to use tool and to improve the acceptance of the method in practice a software-tool with a graphical user interface and an underlying database was developed. This solution now exists as a windows-based program with a well structured input window for each of the different topics.
The assessed parameters are presented finally in a dwg-drawing (figure 3) that is automatically generated by the software. A hierarchical administration of the datasets including a versioning of the assessments is enabled by a freely adaptable folder-structure. As by-product a diagram showing the development of the solid runoff from the uppermost part of the catchment area to the confluence with the collecting stream for all defined scenarios (figure 2). All assessed data can also be presented in report form being automatically generated by the software.
Conclusion
The initial aim of the documentation being a reproducible assessment of relevant parameters as complete as possible including the possibility of a concise illustration and storage of the digital data could be achieved by the out coming result in form of a software tool. In case of an event it is possible to allocate the processes having taken place, to verify the forecasts and to update the assessment in regions where major changes took place. An additional benefit of the tool is a standardized assessment of torrential rivers. Interfaces to export data from the database to other applications such as GIS or modelling tools are possible and foreseen.
