WLS Report 17-2: Advance warning and video documentation as part of the construction of an early warning system protecting from debris flow in Wartschenbach, communal Nußdorf - Debant, East Tyrol (second stage of realization), on behalf of the BMLF
Abstract
The debris flows in the Wartschenbach of 1995, 1997, 1998, 1999, and 2000 were triggered by heavy rain showers, which always reached their highest precipitation intensity in another catchment area of the Wartschen stream. At the same time, most of these thunderstorms were accompanied by hail. Thus, both the inclusion of the precipitation scale of the HD Tyrol in the transmission network and the establishment of another precipitation measuring station in the spring stream Wartschenbrunn on the level of the Hotel Binder is considered to be urgent in the course of the second stage of realization. Simultaneously, a hail detector needs to be included in the early warning system. These two locations guarantee an almost full covering of the catchment area, and they make the latter usable for an early warning system that is based on a precipitation sum measurement as well as a precipitation intensity measurement. In addition to the already existing gauging stations, another gauging station will be set up nearby access Wartscher. This station can be used for speed rating, in connection with the gauging point at the Grissmannsperre. There is intended to be an exact on-the-spot documentation to examine the data collected and thus to evaluate the differences of the gauging stations. At the same time, we intend to install a video camera so as to be able to record the debris flow during a possible event at the intake of the Grissmannsperre, in order to document the debris flow visually.
