The investigated area is located on the southern border of the Ljubljana moor, where we are dealing with peculiar hydrogeological occurrences, the so-called mire pools. These shallow springs in the shape of circular hollows can mostly be found on the border between gravel deposits of the Iška river and the low permeable lake sediments.
In the thesis, the estimates of spring discharges at the edge of the Iška river are given. I have investigated the following watercourses: Ložca, Jevšnik, Strahomerska okna, Brest and Retja. The research covered fieldwork, flow measurements and computer data processing. I have analysed the connection between the spring discharge and the precipitation at the Črna vas precipitation station, as it is the closest to the researched spring. I found out that the springs Jevšnik and Strahomerska okna, located in the northwestern part of the Iška alluvial fan, have a higher yield than the other three streams originating from the Holocene part of the aquifer.
I compared the data of the performed measurements with older data. I only had the measurements taken from Strahomerska okna and the Jevšnik canal. I have discovered that the original discharges at Strahomerska okna are comparable with the values between 1974 and 1980. On the other hand, the average discharge at the time of the measurements, that I have taken, was much higher.
