About the same scale as Giant kelp plant.
Giant kelp plant: Giant kelp is a large brown alga that grows from the seafloor and can form dense underwater forests.
Measurements, assumptions & sources +
Ombla River
The Ombla’s named surface course near Dubrovnik is approximately 30 m from karst spring to ria. Its much larger underground drainage system is excluded, making shortest-river comparisons convention-dependent.

The marked approximate surface-course length is calibrated. Unmeasured illustration details are representative.
Giant kelp plant
A representative mature giant kelp (Macrocystis pyrifera) thallus 30 m from holdfast to longest blade tip. Flexible fronds change shape with current, and a real holdfast anchors to rock rather than forming roots.

Why this measurement?
Why we use 30 m
For comparison, this page uses approximate surface-course length. This is labelled approximate; the central value is useful for comparison, while real values or measurement solutions can vary. The recorded range is 25 m to 35 m.
