This report provides insight into long-term changes in the position of groundwater table in the upland subregion of the middle Vistula River based on the research conducted in seven 1st order hydrogeological stations of the national groundwater monitoring network. These changes reveal a clear temporal relationship/trend noted in the vertical profile of aquifers even in conditions of their significant mutual isolation. They have been described as an effect of the phenomenon, but without establishing its measurable causes. The report indicates that the dynamic of groundwater pressure needs further studies and discussion of hydrogeologists dealing with this topic.

The aim of the study was to describe how the potentiometric surface fluctuations are able to influence on the concentrations of ions in groundwater. The research based on the data provided by the groundwater monitoring network of the Polish Geological Institute – National Research Institute (PGI-NRI) from the Warta catchment in the period of 24 years of record (1991–2014). In the first stage of analysis the measured concentrations of ions: Cl–, Mg2+, Mn2+, Ca2+, Na+, SO4 2–, K+, HCO3 – were examined in conjunction with the groundwater level fluctuations in 29 monitoring points (in case of confined aquifers “groundwater level” was regarded as the potentiometric surface measured in the hydrogeological borehole). There were found statistically significant correlations between some of the concentrations of analysed ions and the fluctuations of groundwater level. Ions: Mg2+ in the point nr 6 and 226, Cl– and Na+ in the point nr 581 were subjected to further testing because their concentrations showed the strongest linear correlation with the potentiometric surface. In the second stage of study, the classical least-squares regression method was applied to build the linear models for these dependencies. The obtained results show that the fluctuations of potentiometric surface were able to explain from 30 to 56% of the variation of ion concentration.

The paper is a result of experience of the Przedsiedbiorstwo Robót Geologiczno-Wiertniczych sp. z o. o. [The Geology and Drilling Works Company] in Sosnowiec as to implementing a comprehensive IT system supporting the geologic and mining activities of mines. The paper provides a description of the central system for information management, with particular attention paid to the data on ground deformation. Beside, the way of creating hydro-geologic models of mines, as well as a the three-dimensional model of settlements has been described basing on the data stored in the central data base. An analysis of relationship between ground settlements and piezometric pressure changes has been made. Calculation formula have been introduced and procedures allowing independent settlement forecasting by relevant mines' officers described.

Artykuł ten jest wynikiem doświadczeń Przedsiębiorstwa Robót Geologiczno-Wiertniczych sp. z o.o w Sosnowcu w zakresie wdrażania kompleksowego systemu informatycznego wspomagającego geologiczno-górniczą działalność kopalń. W artykule przedstawiono opis centralnego systemu zarządzania informacją ze szczególnym uwzględnieniem danych o deformacjach terenu. Opisano sposób tworzenia modelu hydrogeologicznego kopalń oraz przestronnego modelu osiadań na podstawie danych przechowywanych w centralnej bazie danych. Przeprowadzono analizę zależności między deformacjami terenu a zmianą ciśnień piezometrycznych. Wprowadzono wzory obliczeniowe oraz opisano procedury umożliwiające prognozowanie deformacji samodzielnie przez odpowiednie służby kopalń.
