    Opis:
    The groundwater of the Nida valley was investigated to assess the quality of water source and monthly variations of the physicochemical parameters. A total of 70 water samples were collected from 7 sampling sites during a 10 months period from June 2021 to March 2022. Sampling frequency was once per month. The parameters such as temperature (T), electrical conductivity (EC), dissolved oxygen (DO), pH, total dissolved solids (TDS) were measured in-situ by using handheld device. Meanwhile, total nitrogen (TN), total phosphorus (TP), chloride (Cl – ), sulphate (SO42– ), manganese (Mn), iron (Fe), zinc (Zn), cadmium (Cd), lead (Pb), copper (Cu), chemical oxygen demand (COD) were analysed in the laboratory. According to the classification of Ministry of Marine Economy and Inland Navigation in Poland (2019), some investigated parameters are classified as unsatisfactory quality waters (class 4) and poor-quality waters (class 5) for a few specific months. Such as, TP concentrations obtained in June and January are classified as class 4, SO42– concentrations corresponded to classes 4 and 5 in June, July and August, and Mn concentrations (except in January) are settled in class 5. The high values of Fe in November are arranged in class 5 and in June, July to September and March are classified in class 4. Statistical methods were used as: Shapiro-Wilk test (α = 0.05), ANOVA test and post-hoc Tukey test (α = 0.05), Kruskal-Wallis test and Wilcoxon (Mann-Whitney) rank sum test (α = 0.05) estimated the significant differences in sampling months. Pearson correlation analysis (α = 0.01 and 0.05), principal component analysis (PCA) and cluster analysis showed correlation between the parameters and sampling months.

    Opis:
    The aim of the study was to determine the trophic state of the Vistula Lagoon in 2007–2009. The analysis of various trophic state indices, abiotic parameters and different water classifications indicated the eutrophy and even advanced hypereutrophy of the lagoon waters. The composition, abundance and biomass of phytoplankton likewise reflect the eutrophic nature of this water body. For this lagoon, Reynold’s functional groups of phytoplankton were used as an indicator of eutrophication for the first time. The dominant phytoplankton organisms in the surface waters belong to 8 functional groups: S1, X1, F, J, K, H1, LO, M. Some key concepts of the EU Water Framework Directive were implemented in this study.

    Opis:
    The use of polluted water bodies for recreation poses a risk of infectious diseases. This fact necessitates taking into account bacteriological indicators to determine the danger of recreational water use. The aim of the article was to develop a new method for assessing the potential risk to population health during recreational water use. A new method for assessing the potential risk to population health during recreational water use has been proposed, which combines the identification of potential risk according to chemical and bacteriological indicators. A new classification of water hazard levels according to the values of risk to population health has been developed. The value of the potential risk to the population health during the recreational use of 6 beaches in the urbanized territories of the city of Kharkiv and its suburbs (Ukraine) was obtained. It was established that bacteriological contamination has the probability of a very large impact on public health (hazard class 5). To compare the methods of assessing the risk to population health during recreational water use, the hazard index (NI) was determined according to the chemical indicators of the quality of water bodies in the city of Kharkiv. The use of the assessment of the potential risk to population health for the environmental regulation of the discharge of pollutants into a water body with wastewater is justified.

    Opis:
    The Pakoski reservoir .was created in 1975 as a result of damming the lakes located within the Western Valley of the Noteć River. This reservoir operates in rearly cycles with water level fluctuations of up to 3.6 m. The researches carried off by the author in the years 1998-2003 indicate that the thirty-year exploitation period has not ended the intense reshaping phase of the shore zone of the reservoir. Both intensive shore abrasion and various accumulative forms support the above statement. These forms include the small ones of distinctively initial character, such as accumulative spurs or berms, as well as the complex ones whose shaping process has almost finished and the area of which exceeds a few hundred square metres. Due to constant lowering of the water level, accumulative forms occur within the entire width of the shore-platform which is being dried. In most cases these are whole groups of smaller forms related to one another. A beach can constitute a good example, as it predominantly combines a few, most often 5 to 6, adjoining beach ridges separated with small lagoons.

    Opis:
    From a management perspective, water quality is determined by the desired end use. Water intended for leisure, drinking water, and the habitat of aquatic organisms requires higher levels of purity. In contrast, the quality standards of water used for hydraulic energy production are much less important. The main objective of this work is focused on the development of an evaluation system dealing with supervised classification of the physicochemical quality of the water surface in the Moulouya River through the use of artificial intelligence. A graphical interface under Matlab 2015 is presented. The latter makes it possible to create a classification model based on artificial neural networks of the multilayer perceptron type (ANN-MLP). Several configurations were tested during this study. The configuration [9 8 3] retained gives a coefficient of determination close to the unit with a minimum error value during the test phase. This study highlights the capacity of the classification model based on artificial neural networks of the multilayer perceptron type (ANN-MLP) proposed for the supervised classification of the different water quality classes, determined by the calculation of the system for assessing the quality of surface water (SEQ-water) at the level of the Moulouya River catchment area, with an overall classification rate equal to 98.5% and a classification rate during the test phase equal to 100%.

    Opis:
    The post-glacial areas are characterized by favorable conditions for the formation of wetlands as a result of the widespread occurrence of depressions without outflow - center for the development of wetlands. The studies of morphogenetic conditions of the wetland development in Volhynian Polissia within the territory of Ukraine and the formation of their water regime reveal several features of their distribution and typological variety. The location of wetlands were characterized in reference to the shape of base/subsoil and its lithology. The typical structure of post-lacustrine, paludificational, riverside and spring peatlands of the Volhynian Polissia were shown and their development were also discussed. The wetland evolution under the influence of the postglacial landscape degradation leads to disappearance of the depression wetlands in glacial forms, increase of the peat bog trophicity and the level of peat dissolution. The supply conditions and characteristics of water regime are determined for separate peatlands. According to the origin and water flow/supply four types of wetland were extracted: ombrogenic, topogenic, soligenic and fluviogenic. It was found that the reasons of the high marshes areas (21%) in Volhynian Polissia are the geological and geomorphological conditions retaining/stopping the runoff and also local groundwater circulation system.

    Opis:
    The aim of the research described in this paper is to classify groundwater level patterns in pine stands of forest fresh sites. The approach has been employed with the view to facilitate explaining interactions between physiographic characteristics and groundwater dynamics in prospective research. The methods which have been employed so far for explanation of groundwater level dynamics interactions with local physiographic conditions do not let to draw firm conclusions. The classification of groundwater dynamics patterns requires employing more sophisticated methods, because of a relatively extensive range of groundwater dynamics site-to-site variability expressed, e.g., by amplitude and cycle period. The methods of groundwater patterns classification proposed in the literature focused either on hydrogeological criteria or, if related to forest ecosystems, focused on water balance elements in forest habitats. The area selected for investigation represented typical features for the Northern European Lowland forests defined by soil and form of terrain pattern shaped by the last glacial period (Vistulian glaciation) and dominant share of Scots Pine (Pinus sylvestris L.) in stand species composition. The research period covered the 2002-2007 hydrological years. The measurement used in analysis covered 35 sites equipped with measurement wells.

    Opis:
    Estuaries are transition zones between the land and the sea which form aquatic ecosystems, often referred to as marginal filters. Numerous classifications of estuaries are based on such criteria as: geomorphological structure, the character of water circulation and stratification, the ratio between freshwater and marine water and the type of energy flow. However, not all estuaries fall into one of the above categories. Some of them represent an intermediate type, while the type of others may change depending on the season and related changes in water inflow rate. Fisheries, including bi-valve mollusks, depend on the high productivity of estuarine areas, which can be also used as ports or sites of recreation and industrial activities. Estuaries play a fundamental role in maintaining an ecological balance in the biosphere.
    Estuaria to tereny przejściowe pomiędzy lądem a morzem, które tworzą wodne ekosystemy, często nazywane „filtrami brzeżnymi”. Liczne klasyfikacje estuariów oparte są na takich kryteriach, jak: struktura geomorfologiczna, charakter cyrkulacji i stratyfikacji wód, stosunek dopływających wód słodkich do morskich oraz typ przepływu energii. Nie wszystkie estuaria można zaliczyć do jednej z przedstawionych kategorii. Niektóre z nich stanowią typy pośrednie, inne zmieniają typ z jednego w drugi, w zależności od pór roku i związanych z tym zmian tempa napływu wód. Wielka produktywność estuariów może być wykorzystana przez człowieka do produkcji żywności w formie hodowli ostryg, małży i rybołówstwa; mogą służyć jako porty, rejony rekreacyjne i ośrodki przemysłowe; mają również ogromne znaczenie ekologiczne dla zachowania równowagi w biosferze.
