ABSTRACT: A recently developed method of karst spring hydrograph separation, based on iterative solution of several simple exponential and linear equations, was applied on two-year (1987 – 1989) weekly discharge time series of four karstic springs in the Brezovské Karpaty Mts. (Slovakia), built mainly by karstified Middle and Upper Triassic dolomites and limestones. Every spring was described by unique sets of starting discharge Q0 and recession coefficients ? (laminar flow component in exponential equations) and ß (turbulent flow component in linear equations). Discharge components (subregimes) were detected by recession curve analyses of the spring’s discharge time series. Every measured discharge value, Qt, was determined by a representative time, t; i.e., the theoretical elapsed time t from the total maximum discharge value Qmax. Iteration process was used to obtain representative time t for each discharge Qt. Variations in different flow component discharges in a given time were linked to simultaneously measured water quality parameters, in order to obtain the end members of the theoretical mixture. Additional characteristics of end members were calculated, such as groundwater temperature and ?18O content although the method was based on relatively sparse datasets and manual discharge records, and therefore represents a perspective method for future development and interpretations on limited dataset results.
