What does this number measure?
The Sorgue rises at Fontaine-de-Vaucluse, a major karst spring. In the Comtat plain, it splits into several branches, notably around L’Isle-sur-la-Sorgue. The 30.4 km reference concerns a conventional river-course length; the branching network cannot be reduced to a single natural ribbon.
This length follows the course adopted by the catalogue. Maps show simplified, sometimes partial courses; an independent bar represents the documented length, distinct from straight-line distance.
Compare the stated dimensions
The comparison uses the number in each fact sheet: altitude, height, diameter, length or distance, depending on the reference. Two values in metres do not necessarily describe the same property.
Source and limitations
The choice of channels and network endpoints changes the length; 30.4 km is a rounded reference value, not a sum of all the channels.
Top view of a simplified geographic course of Sorgue (Vaucluse), based on the available mapped segments. The reference drawing may be partial, and river systems may combine several branches. River width and the textures of water and banks are interpreted; this is not a satellite photograph. Only the lower bar represents the documented reference length; the width of the map above does not measure that length.
