The content of the PGI-NRI databases in terms of research on discharges of springs in Poland.
A b s t r a c t.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 dm3·s–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.
