In close cooperation with the BfG and its UNDINE portal, the ICPR has developed a low water monitoring system.
With the uniform Rhine-wide low water monitoring system, current low water events can be directly compared and classified and possible changes in the low water discharge can be detected.
The attached report (and its partial update in 2024) present the methodology behind the ICPR's low water monitoring system. The attached explanation report 261 is available in German, French and Dutch. The updates are available in English.
The ICPR low water monitoring can be consulted here in the form of a complete catchment area map of the Rhine with information on the Rhine gauges.
