Water knowledge
Understanding Greuelbach
Greuelbach: this overview puts the available stations and measurements in context. The exact location matters, not just the water body's name.
This overview includes 3 monitoring stations for water level, discharge, and water temperature. Not every station provides every measurement. Track changes at the same station, checking the timestamp, unit and source notes.
Discharge in m³/s is a volume per second, not the speed of the current. Station comparisons must account for location, measurement time and water travel time. A higher reading is neither automatically a flood warning nor an indication that the river is navigable.
