Water knowledge
Understanding Melera
Melera: this overview puts the available stations and measurements in context. The exact location matters, not just the water body's name.
This overview includes 1 monitoring station for water level. Not every station provides every measurement. Track changes at the same station, checking the timestamp, unit and source notes.
A gauge records water-surface height at its location, not depth throughout the river. Centimetres on a local gauge and metres above sea level use different reference points. Discharge in m³/s cannot be derived without the station's specific relationship between level and discharge.
