“The Krka River estuary has a total length of 22 km and was formed during the Late Pleistocene – Holocene transgression. Input of terrigenous clastic material into the Krka River estuary is small, with the main input of the particulate material via small Guduča River. The length of freshwater part of Krka River is 50 km and the hydrological situation of the catchment is very complex and not yet fully explained. Tufa precipitates on the entire course of the river, forming several up to 50 m high barriers and cascades and stretching over several 100 m in length. Due to, the biological and geological characteristics of the region, and the picturesque scenery of tufa cascades, lower part of the freshwater river region is protected as a National park.
