Karst, travertine and waterfalls – multimedia films for innovative teaching

 

The Public Institute of Krka National Park has made three new educational films of five minutes each on the phenomena of the protected area. They are intended for use in formal and informal education.

New technology today is an unavoidable part of life and can also be considered a tool that enables a different approach to learning. Karst, travertine and waterfalls, as the components that make up the phenomenon of Krka National Park, are the themes of these films. Each film shows stunning scenes of nature, with short information on the importance of what is being shown, over a relaxing musical backdrop. The films can be used as a supplement to individual teaching units, or independently when discussing the Krka River. This manner of education attracts pupil attention and enables between understanding and absorption of the content, and is ideal for supplementing field studies in the park itself.

Karst, travertine and waterfalls have an unbreakable connection with the hundreds of thousands of years needed for the processes to create the unique beauty that today we protect as Krka National Park. Water destroys and changes the form of the rock and the appearance of this area. First the plateau was created, and then the river carved a canyon deep down, and later the travertine barriers were raised around which the entire ecosystems of the present day park were formed. For this reason, the video on the travertine barriers is the first in the series to be presented.

When the great and powerful Krka River calmed its waters, the seven travertine barriers rose up from the deep. The first, Bilušića buk, is pressed into a canyon, 16 km downstream of the source and 9 km downstream of Knin. The entire flow of the Krka River flows over this barrier, and in the film you can see how it once looked, before it was partially blasted to reduce flooding of the surrounding areas. Following this are the barriers Brljan, Manojlovac, Rošnjak and Miljacka, aquatic gems in the dry and karst upper course of the Krka River. Brljan is surrounded by dense forest vegetation, Manojlovac is known as the tallest waterfall on the Krka River, and Rošnjak the smallest. In terms of the number of moss species, Miljacka is by far the richest waterfall, and can be considered a hotspot of moss diversity. In the very middle of the river’s course, lie a series of travertine cascades, which the people call the Necklace. When the water passes over them, it then falls over the wide fan of Roški Slap, crashing down into the lake. Before the Krka drains into the sea, the combined waters of the Krka and Čikola Rivers spill over the 17 steps of the best known and most visited waterfall on the Krka River - Skradinski buk. Even though the waterfalls appear like monuments, as exceptional works of art, they are in fact living organisms that grow and change, shaped by processes invisible to the naked eye.

Each of the films ends with the message that it is necessary to protect and preserve these sensitive conditions needed for the process of travertine-building, in order to ensure the survival of the entire Krka River basin. The Public Institute of Krka National Park is dedicated to this aim, and holds a number of educational workshops with children, to teach them about the area in which they live and the importance of its conservation, for the benefit of us all.
