The source area (headwaters) of the river Tiebel consists of over 40 sources (some say 60 to 100), and is therefore with a constant average water capacity of approx. 660 litres per second, the second largest source region of Carinthia.
The quantity of water flow is equally high all the year round, independent for the most part of snow melt and precipitation.
The temperature (about 7 ° C) at the outlet of the spring is also virtually constant, so the sources, but also the river Tiebel itself, never freeze, even when temperatures are extremely low.
Where does the water come from?
The Tiebelquellen , on the one hand, are composed of seeped water from the river Gurk and groundwater flow from the upper Gurktaler fed on the other hand, which comes to light through sources, arranged on different levels, a few months later.
How it all began:
A glacier that spread from lake Ossiach to the Prekowa dammed the river Gurk and forced it into a new river bed flowing in a northeasterly direction through the "Enge Gurk" - its present course.
When the glacier retreated, erosion tapped the aquifer of the upper Gurktal and the Tiebelquellen were created.
To gain permission to log, please answer the following questions:
Question 1: What hydrogeological feature of the Tiebel sources is unique in Europe?
Question 2: How long is the retention in the soil before the water escapes from the source?
( To prove that you have been at the location, go to the header coordinates and tell us which creature is sitting on the trunk, and since when? )
The prove has gone - victim of the nature, so ... of course, a beautiful photo in the log is always welcome too :-)
