摘要:The thesis deals with the hydrological analysis of the Malenščica karst spring and its catchment.The analysis comprises the results of a water balance method, hydrograph analyses, the basic descriptive statistics of different hydrological time series as well as of the correlation and multiple regression analysis of hydrological parameters.The principal methodological approach used in the research is the statistical analysis of the time series of daily and hourly hydrological data acquired and measured in the relevant hydrological years 1975, 2008 and in the sequence of five hydrological years 1997-2002, comprising an univariate and bivariate correlation and spectral analysis of data on discharges, precipitation and the physical-chemical characteristics of the discussed spring as well as other springs and watercourses in its catchment and its vicinity.Valuable additional information on water circulation in the catchment of the discussed spring was provided by a combined tracer test conducted in May 2008, when two different tracers were injected into the ponors of two contributing branches of the common catchment of the Unica and Malenščica karst springs (the Postojna Cave, the Mala Karlovica cave).
