Hydrogeochemical and stable isotope properties of the dripwaters in the caves of the Moravian Karst (Czech Republic)

Original language description

The dripwater hydrology and chemical parameters are used to determine water flow paths and reservoir properties of upper karst. This work was aimed to advance previous research in Moravian Karst (Czech Republic) with data on the isotopic composition of the water. The study is focused on the stable isotopic composition (δ18O and δ2H) and hydrogeochemical properties (i.e., EC, T, discharge, pH, alkalinity, Ca2+ concentration or mineral saturation) of samples systematically collected quarterly between fall of 2018 and spring of 2020. The observed stable isotope composition naturally reflects the origin of the dripwater from a meteoric water. The results show higher variability of isotopic composition in seasonal drips with variable discharge, whereas one of the permanent drips shows very low isotopic variability indicating the isolated and well‐ mixed source of water from epikarst. Also, a somewhat similar behaviour of isotopic composition was observed in a drip with anomalous hydrochemical composition (caused most probably by prior calcite precipitation in upper cave levels). Finally, the isotopic composition of the underground river Punkva in the same cave system was studied for comparison and it shows isotopic enlightenment with respect to dripwaters.
