Summary: The paper shows the analysis results of the catchment area
ofthe karst spring Sv. Ivan. The important problem is to define thedrainage
divide and the drainage area. The undergound watershedhas been determined
by the geological an hydrogeological methods.The control has been performed
by the water budget, by analysisof the spring discharge as the function of
the drainage area, theheight of the rainfall and evaporation. Runoff
coefficients fromthe drainage area have been defined. The spring Sv. Ivan
includesthe springs zone with the main spring and several small springs.The
water in the spring penetrates the flysch layers - marls andsandstones
which limit the maximal values of the springdischarge. That is the reason
why the discharge is fairly uniformin comparisson with other karst springs.
The catchment areaincludes the mountain karst hinterlad with height above
thesea-level from 50 m at the spring itself, up to more than 1000 mat the
boundaries of drainage area. The catchment area has thevalue of 74 km2. The
karst area occupies about 50 km2, and theflysch area 24 km2. The ratio of
the maximal and minimal springdischarge is from 1:10 to 1:12.
