With climatic changes, access to freshwater resources becomes more limited. Correspondingly, water monitoring methods in sensitive or critical areas in terms of groundwater amount are becoming increasingly important. The monitoring of the water levels in these regions, using appropriate methods and data sets, is highly effective in preventing possible future water crises. This paper aims estimated water storage changes with available tools and data in southeastern Anatolia, Turkey, where hydroclimatological studies are scarce due to limited observations. Data obtained from the Gravity Recovery and Climate Experiment satellite mission and the Global Land Data Assimilation System were used for the analysis of water storage changes in the study area. The results demonstrate that water storage shows a downward trend in all subareas, particularly in high-elevation regions. In addition, climatic changes have both short- and long-term impacts on water storage. Climatic variables (increasing temperature and decreasing precipitation) showed the highest correlation with water storage at 2-month lags. The monitoring of water storage is crucial for the region, and our results confirm the major role of such monitoring in decision-making processes and water resource management.

Przed podjęciem decyzji o modernizacji systemu zaopatrzenia w wodę aglomeracji gdańskiej konieczna okazała się szczegółowa analiza uwarunkowań formalnoprawnych gospodarowania zasobami wodnymi. Artykuł prezentuje najważniejsze wyniki tych prac. Na podstawie wyników, publikowanych i zawartych w hydrogeologicznych dokumentacjach badań, dokonano oceny zasobów wód podziemnych dostępnych do zagospodarowania przez ujęcia miejskie Gdańska i Sopotu. Szczegółowo przeanalizowano różne warianty zaopatrzenia w wodę. Zarekomendowano dywersyfikację źródeł pozyskiwania wody i wykazano zalety takiego rozwiązania.

Detailed analysis of legal acts was done before making the decision of Gdańsk water supply system modernization. The paper presents the main results of this analysis. The groundwater resources exploited by the municipal water intakes of Gdańsk and Sopot were recalculated based on published papers and hydrogeological documentations. Different scenarios of water supply have been developed for the future water management in these cities. A diversified water supply system from many sources is recommended and the profits are presented.

TheWater Framework Directive (WFD) established in 2000 expresses a general EU policy orientated towards protection, sustainable utilization and improvement of the quality of water bodies. Poland signed the accession treaty with the European Union in 2004. It was automatically obliged to comply with tasks specified in existing European directives. It was for that reason that in 2002, when Poland was preparing for accession to the EU, Poland transposed the requirements of the EU Water Framework Directive into the Polish legal document concerning the State’s water policy known as theWater Act. Fulfilment of the WFD’s objectives was defined in theWater Act through works of the Polish Hydrogeological Survey (PHS) established in 2002 within the Polish Geological Institute, following implementation of the Water Act. Since 2007, PHS received new duties resulting from the EU Groundwater Directive (2006/118/EU) on the protection of groundwater against pollution and deterioration (Official Journal EU L 372 from 12.12.2006). There are also hydrogeological obligations that result from another piece of national legislation called the Geology and Mining Act regarding thermal, saline and mineral waters, which are classified in Poland as mining resources. Fresh water resources are within the scope of the Water Act. At present, we observe a significant increase in usage of these resources, especially for geothermal energy and for recreational and therapeutic uses. Nevertheless, even curative waters must be considered in a systematic way, in connection with surface water and shallow groundwater, as their availability is controlled by infiltration from shallow groundwater or directly from infiltrating rivers and streams. Groundwater bodies delineated by the PHS have to be monitored and results of this monitoring are further transposed to river basin action plans. Some groundwater bodies are situated along the Polish boundary zones and these have to be controlled by both sides: PHS and the corresponding services of the neighbouring countries. The most important task for both sides is to achieve good groundwater status for trans-boundary groundwater bodies, water supplies for citizens and water dependent ecosystems. There are legal, organizational and research tasks within the monitoring schemes and water management planning projects, which belong to the duties of the PHS.

The PSH Database Integrator as a sophisticated tool for groundwater management answers the needs of the Polish Hydrogeological Survey. At the first stage it is a functional integration system for all hydrogeological databases existing in the Polish Geological Institute such as those of Groundwater Monitoring, HYDRO Bank and Hydrogeological Map of Poland. The final stage of all kind of analysis involves cartographical representation of the results. Using the PSH Database Integrator in this process reduces labour input and time as well as helps keeping standards. Next stage in the system development will enable internet access for users.

Głębsze systemy zwykłych wód podziemnych, dobrze izolowane, o naturalnym składzie chemicznym i właściwościach fizycznych, stanowiące swoiste pomniki przyrody, wymagają szczególnej ochrony i racjonalnego użytkowania.

Fresh groundwater of apparently natural chemical composition and physical properties, which occurs in aquifer-systems at greater depths and isolated by geological barriers, constitutes simultaneously a unique environmental archive and monument, therefore, it should be protected in a more rigorous way and rationally managed.
