The paper presents the result of the study of 16 springs in the Julian Alps and Karavanke, where the measurements of the water chemistry and measurements of oxygen, carbon and hydrogen isotopes were carried out in order to estimate the hydrogeology of the alpine aquifers. The results showed that aquifers in the Julian Alps are more vulnerable due to shorter retention times and thiner soil layers.

In this study we observed how in-stream gravel extraction affects hyporheic invertebrate community, the hyporheic geomorphology, physico-chemistry of the interstitial water and biofilm activity. Invertebrate densities and taxonomic richness recovered relatively fast, while it took 5-7 months that invertebrates recover by means of community composition. The impact of fine sediments ((0.1 mm) on biofilm activity and hyporheic invertebrate density and taxonomic richness was strongly confirmed in this study.

During the in-stream gravel extraction the invertebrates are removed from their habitat, partly with gravel and partly they drift downstream. In this study we measured drift during the gravel extraction and observed how invertebrate drift change with the distance from the excavation and over the time.
