In Realp (canton Uri, Switzerland) inundations can take place if the river Reuss has a high water level (> HQ50, depending upon sediment discharge). Such situations can happen rather fast and unexpectedly. In order to prevent inundations, temporary safety measures for buildings are installed.
For the monitoring of the water level of the river Reuss and the alerting of the task forces, different measuring instruments were installed. For preliminary warning in the catchment area, precipitation and temperature measuring points were built.
The measuring data are transferred by means of light wave cables and/or GSM connection to a computer in the train station of Realp. Beside the automated evaluations, visualizations and alerting on location, the data will be led to the specialist department of the canton in a later project phase. Thus both local as well as superordinate decision makers are supplied with the relevant flood data in the demanded time intervals, relevant for them.
