The previously mentioned mechanical and chemical dissolution processes are regularly occurring natural phenomena.
A unique process occurring at the Plitvice Lakes, however, is the sedimentation of water-bound chalk at certain places.
With regard to other similar phenomena in the world, at Plitvice Lakes the sedimentation of chalk and the formation of tufa happens dynamically all along the watercourse and in various forms (fluviatile sedimentation).
It is thus not a static phenomenon occurring at only single places.

Another unique and distinctive feature are the natural factors, particularly the influences of the vegetation in the process of sedimentation.
While passing the vegetation, barriers are being created by foaming water.
These naturally created barriers decelerate and dam the waters, thus forming lakes.
At Plitvice, this constant interplay between water, air, rock and vegetation can easily be observed.
The foaming water creates ever growing and impressive waterfalls.
The thresholds grown up above the water level, create cataracts.

About 30 km (18.64 mi) north of the lakes at the conflux of the Korana and Slunjčica rivers, right in the center of the town of Slunj, similar phenomena occur.
This part of the town, called Rastoke, is often being referred to as "the Small Lakes of Plitvice."
