The paper presents an analysis of the content of the PIG-PIB databases in terms of information on discharges of springs in Poland. In general, the information covers about 87 springs. They are compiled in two databases: the Quantitative Monitoring Database (MSI) and the Central Hydrogeological Data Bank (CBDH). The measurement series concerns the period 1973-2016, and there are 41 springs still monitored. Most of the observed objects are small springs (class VI) with the average discharge of only 0.33 dm3s-1. Unfortunately, the biggest problem is the lack of series synchronization. Their length ranges from a few months to almost 40 years, but 39 outflows is observable for less than a decade. Most of the springs (57) represent Paleogene Carpathian flysch sediments, 27 Sudetic rocks, 2 karst springs are in the Cracow- Częstochowa Upland, and only one is located in Pomerania. The lack of data synchronization makes it difficult to conduct some analyses, but does not exclude the use of other quantitative characteristics of springs, e.g. in the research of seasonal and long-term discharge variability. The variety of selection of objects can also help in an evaluation of the impact of environmental factors on the spring outflow.

Potok Bukowy jest prawobrzeżnym dopływem rzeki Brennicy, a zlewnia leży w granicach administracyjnych gminy Brenna. W zlewni potoku o powierzchni 2,76 km2 zidentyfikowano 15 źródeł, w których w 2014 r. wykonano kilka serii pomiarów wydajności. Otrzymane wyniki umożliwiły klasyfikację źródeł pod względem ich wydajności w odniesieniu do wartości podawanych w literaturze. Ponadto uzyskane wyniki umożliwiły określenie wielu parametrów, wśród których można wyróżnić: zmienność wydajności źródeł, stopień uźródłowienia terenu, wydajność źródeł w oparciu o klasyfikację Meinzera oraz na podstawie prowadzonego monitoringu przepływów wody w przekroju zamykającym określono współczynnik drenowania zlewni. Prowadzone równocześnie pomiary przewodności elektrycznej i temperatury wody w umożliwiły wyodrębnienie zbiorników alimentacyjnych dla poszczególnych źródeł.

The Bukowy stream is the right-bank tributary of the Brennica river, and the river catchment is situated within the administrative borders of Brenna commune. In the stream’s 2,76 square kilometer catchment 15 springs have been identified, in which several series of discharge measurements were made in 2014. The results allowed the springs to be classified according to their discharge capacity in relation to the values existing in scientific literature. Moreover, thanks to the results, it was possible to define numerous parameters such as: variability of spring discharge, degree of springs occurrence in a given area, capacity of springs according to Meinzer’s classification; and basing on the monitoring of the water discharge in the cross-section closing the catchment its draining rate was determined. The simultaneous measurements of electrical conductivity and temperature of water allowed to separate maintenance tanks for given springs.

The long-term characteristics of the discharge regime in European springs are not well known yet. In presenting the springs, stress should be laid on their discharge variability and seasonality. The paper presents mean monthly discharges in 86 springs from four countries: Austria, the Czech Republic, Germany and Poland, measured over a period of several years. The analyses were based on discharge variability coefficients (V R, CV) and Markham's seasonality parameters: seasonality index and time of concentration. The results were interpreted with reference to three basic types of hydrogeological outflows: in karst, fissure and porous springs. The regime of most investigated springs is complex (57% of all springs), and nival supply clearly dominates over precipitation supply (49% vs.8 %). Nival supply dominates also among the springs with simple regimes, as a culmination of the discharge in 35% of these outflows was observed in the spring months. In the karst spring, characterized by higher seasonal discharge, it occurs on average about three weeks later than in the fissure springs. The seasonality index of the porous outflows is several times lower, and the discharge concentration time occurs at the beginning of May. Seasonal spring discharge wasfound to be correlated with the spring elevation; the discharge of springs located at higher elevations is characterized by greater seasonal variability and later concentration date.

The paper presents the 12-years discharge variations of the three springs located within the Pieniny National Park. The background was the observations of the water table variation in the springs and seasonal measurements of the springs discharge, which made the possibility of calculation of the rating curves. Generally, the Pieniny springs are characterized by low discharge. The mean discharge of the springs studied for the period 2003–2014 was as follows: spring of the Potok pod Wysoki Dział – 1.66 dm3s‒1, spring of the Kotłowy Potok – 0.26 dm3s‒1, seasonal spring of the Kirowy Potok – 0.10 dm3s‒1. Variations of the springs discharge are different due to the fact that particular spring drain separate, and relatively small groundwater reservoir. First of all, the influence of the many-years variation in the sum of atmospheric precipitation as well as the amount of infiltrating meltwater can be observed. Observations with monthly distribution showed the characteristic shift between maximum discharge of the spring and the sum of atmospheric precipitation (about 1 month shift) as well as the thawing period (1–3 months shift). Presumably, during dry seasons the springs have mainly the thawing regime, in the normal (balanced) seasons – the thawing-precipitation regime is dominant, and during the wet season – the precipitation-thawing regime prevails. In the years 2012 and 2013 the sudden decrease of discharge of the Kotłowy Potok and Kirowy Potok springs have been observed which is in well agreement with the hydrogeological drought identified in Poland.

Spring water discharge and physicochemical properties were investigated in four springs of the Szreniawa catchment. The catchment is located in the western part of the Miechów Upland and is composed of Cretaceous marls and limestones. Spring discharge was measured in two-week intervals from February to November 2011. The water was being sampled for chemical composition once a month. The aim was to determine discharge changes in the springs and physicochemical properties of water. Relationships between the properties of water in the years 2000–2011 have been also analyzed. All the examined springs are characterized by a steady discharge. According to the Meinzer’s efficiency classification, most of the springs belong to class III. The total average spring discharge is about 496.4 dm3 · s–1. According to the Shchukarev–Priklonskii classification, these waters represent the HCO3–Ca type. The samples are characterized by a relatively high mineralization of water in most springs exceeding 500 mg · dm–3. The springs located nearby can be very different in terms of chemical composition of water, which is controlled by the variations in aquifer rock lithology and local groundwater horizons. The total dissolved solids, concentrations of Ca2+ and HCO3 measured in 2011, were always higher than in 2000. It may indicate an increase in the aggressiveness of the water.

W artykule przedstawiono hydrogeologiczną charakterystykę źródeł w zlewni rzeki Pławnej na tle budowy geologicznej i geomorfologii obszaru, określoną na podstawie kartowania hydrogeologicznego, okresowych obserwacji wybranych źródeł oraz analizy fizykochemicznej wód źródlanych. Uzyskano wartość wskaźnika krenologicznego równą 1,33, a moduł odpływu krenologicznego określono na 0,69 l/s×km2. Na podstawie analizy regresji wydajności źródeł obliczono współczynniki regresji zawierające się w przedziale od 0,010 do 0,028 oraz potencjały zasobności badanych stref wodonośnych w granicach 2,42–10,12 tys. m3.

The paper presents hydrogeological characteristics of springs in the Pławna river catchment against the geological background and geomorphology, based on hydrogeological mapping, periodical spring observations and physicochemical analysis of spring water. Spring density index is equal to 1.33. Total spring discharge comes up to 0.69 l/s×km2. On the basis of springs discharge regression analysis, regression coefficients (0.010–0.028) and capacity potentials of examined aquifers (2,420–10,120 m3) were estimated.
