abstract = {Decisions to build or remove dams and other large engineered hydraulic infrastructures are always entangled in social and environmental impacts, which are often evaluated formally through bureaucratic processes. In Europe dam removals are relatively infrequent, even though extensive hydraulic infrastructure has degraded biodiversity and water quality. The Wilkówka dam in southern Poland was required to be removed rapidly, primarily due to engineering failures during its construction. Using survey methods, we examine the local community's perceptions of the net environmental and social impacts of the Wilkówka dam removal. In surveying the opinions of households, 62% of respondents expressed that decisions about the removal were taken without sufficient community consultation, and 92% felt that the dam had been removed despite their opposition. Although the dam had been built recently and had failed to operate at design capacity, respondents reported strong attachments to the services they perceived it to provide, including water supply, flood regulation and cultural significance. In spite of the possibility of an environmental disaster and long-term environmental degradation, most surveyed households would have preferred it to have been renovated or reconstructed. In short, the removal of the Wilkówka dam was perceived by local households but also by local officials as bringing about a net loss in socially relevant ecosystem services, despite the urgent need for removal perceived by regional and national authorities. The local community's rapid attachment to the dam despite its potential negative impacts on biodiversity and the local environment were primarily attributable to the high expectations as to the hydrological services that the dam was to provide (water supply; flood regulation and its larger symbolic value as an infrastructural investment in the community). This work provides an empirical demonstration of the importance of understanding the social, ecological and technological context within decision-making processes regarding dam removals, and its implications may improve the planning and implementation of future dam removal projects. © 2024 The Authors.

abstract = {Maintaining the appropriate capacity of a retention reservoir is necessary for the optimal performance of the functions for which it was built, including flood and drought protection. Therefore, to properly manage individual reservoirs and sediments within their catchments, it is necessary to analyze the factors affecting the reduction of the retention capacity of reservoirs. Our study proposes a methodology for conducting a multi-criteria assessment of anthropogenic pressures and natural impacts affecting the reduction of reservoir capacity, such as land use, hydrographic network density, hydraulic development, and land slopes. For this purpose, geospatial analyses were applied to a grid of basic fields (hexagons). The research procedure showed that land slopes in the catchment area are the key factor determining the supply of sediment to the reservoir. Our study focused on the basins of reservoirs located in the southern part of Poland: Goczałkowice on the Vistula, Rozn _ ów on the Dunajec, and Tresna on the Soła. However, our proposed new approach to multi-criteria assessment of reservoirs can be applied to and implemented in other catchments. The application of solutions based on our study may contribute to maintaining or potentially increasing the level of water retention in reservoirs and their catchment areas.

abstract = {In August 2022, the Oder River experienced an ecological disaster, resulting in the extinction of hundreds of aquatic organisms. Mass fish deaths also occurred during that time in the Gliwice Canal, located in southern Poland, which connects to the upper section of the Oder River. The aim of the article was to assess the impact of the waters from the Gliwice Canal on the water quality changes in the Oder River, as expressed by chloride, sulphate, nitrate, phosphate content, as well as its parameters such as conductivity, temperature, and pH. Statistical analyses were conducted based on our own research and a series of data collected by the Chief Inspectorate for Environmental Protection. Below the confluence of the Oder River with the waters of the canal, an increase in sulphates levels and a decrease in sodium content were observed. The other parameters remained unchanged. It was also noted that the magnitude of each parameter was significantly higher in the waters of the Gliwice Canal compared to the Oder River. The research conclusion is that there is no influence of the canals’ waters on the quality of the Oder River waters, both during the ecological disaster and afterwards. The presented research clearly indicates the need for separate analyses of flowing waters (with significantly higher salt and other pollutant dissolution capacity) and stagnant waters in water infrastructure (without water exchange). © The Author(s) 2024.},

abstract = {Study region: The research was carried out in 38 rivers in the Oder and Vistula basins. They are located in various parts of Poland, which are geologically, geomorphologically and anthropogenically diversified. Study focus: The paper deals with the inconsistency and incorrectness of applied spatial data in water management. This is caused due to the lack of a unified method of creation and different data sources. The analysis covered three databases used in Polish water management: the digital Map of the Polish Hydrographic Division (MPHP), the Database of Topographic Objects (BDOT) and the Drainage System Database (EM). The Geographic Information Systems and statistical methods (Pearson's; Kendall's and Spearman's coefficients) were used to study the occurrence and size of discrepancies in Polish databases of surface waters. New hydrological insights for the region: The study showed that in the analysed databases there are discrepancies in the nomenclature (47% cases) and watercourse lengths (geometric and attribute – 97% cases). The examined databases differ in the course and mileage of the same watercourse. The research results showed high consistency of BDOT and MPHP and the highest values of discrepancies when compared with EM. A significant statistical dependence of these discrepancies on land cover with dense vegetation was also found. The research proves that it is important to be careful about the certainty of using these data and shows how this can negatively influence water management system effectiveness. © 2023 The Authors},

abstract = {The following databases contains information on land use with water in Poland: Corine Land Cover (CLC), the Urban Atlas (UA); Database of Topographic Objects (BDOT) the digital Map of Poland’s Hydrographic Division (MPHP); and the Register of Lands and Buildings (EGiB). All these data are referenced in scientific analyses and the Polish water management system, so the results of their processing should be the same (or at least similar); if not, output materials will be inconsistent and unreliable. In the Katowice sample, we checked the quality of this data using multi-criteria analyses, which is based on a grid of equal-area hexagons. Additionally, we applied the Normalized Difference Water Index to check real-time water presence. We detected discrepancies between all the data. The CLC does not reference any flowing water in Katowice. Most data overlapped between MPHP and BDOT, and both databases were similar to UA. However, a lot of uncertainty was also observed in the EGiB, which is considered to be the most accurate of the databases surveyed. In conclusion, we argue that water land cover data should be used with caution, and depending on the scales of analysis, that most actual data could be remote sensed data. We also include a diagram which can be useful in the data selection process. © 2023 by the authors.},

abstract = {Starting from the second half of July, hydrological conditions (low water levels and low flows) and atmospheric conditions (high temperatures; lack of precipitation) contributed to algae bloom in the Oder River basin. The mass extinction of fish in the middle and lower section of the Oder was probably the result of such environmental conditions. Because algae bloom is correlated with an increase in the content of chlorophyll in the river and on its surface, the authors focused on an analysis of changes in the chlorophyll amount in the longitudinal profile of the river. The key data was obtained by soundings carried out at an interval of about one kilometre during the research expedition, which took place on July 16–24, 2022. These data coincided with the values of the NDVI index (normalised difference vegetation index) based on 10-metre satellite images from the Sentinel 2 mission. Imagery from cloudless periods (mainly March; June; July and August) processed using the NDVI index was compared. Regularly elevated chlorophyll levels in the upstream section (occurring in each period) and temporarily elevated chlorophyll values as moving downstream were observed. This article confirms the initial conclusions of Kolada et al. (2022) that the mass fish kill in the Oder River in the summer of 2022 was conditioned by natural environmental pressure causing massive algae bloom and the release of their toxins. The article also proves that the use of satellite images for this type of analysis is the correct approach, but due to low resolution, they cannot be used as reference material. Changes in the hydrobiological parameters of the river, which are a direct indicator of the causes of the ecological disaster, are the data of the multi-parameter probe obtained two weeks before the first mass catches of dead fish. © 2023},

abstract = {Background: Secondary salinity of river water reduces the value of ecosystem services, negatively impacting the entire aquatic ecosystem and reducing the possibility of water use. In Poland, significant anthropogenic salinity of rivers and water reservoirs is usually associated with mining activity consisting of pumping salty mine water into settling ponds or often directly into rivers. However, to assess the reasons for the salinity of the Vistula waters, it is necessary to identify all sources of salt in surface waters, enabling the assessment of the salt load in the waters. Methods: The paper presents four sources of data which have been compiled to propose a valuable method for analyzing the threat of the river. Patrol monitoring was one method of data acquisition, and State Environmental Monitoring data ware also used. Clustering and correlation statistical techniques were used for analysis. Results: Of the 20 physical and chemical parameters analyzed, chloride, calcium sulphate and magnesium ions are important for salinity. Measurements with multi-parameter probes allowed for the identification of increased salinity pressure sites, while flow analyses were required to calculate the load. Conclusions: The Vistula River had the highest concentrations of the analyzed ions in the Silesia Region. The use of patrol monitoring can be highly useful in determining the causes of emerging problems with water quality and supporting State Environmental Monitoring. © 2023 by the authors.},

Therefore, detailed analyses covered mountain reservoirs with varying degrees of capacity changes: Goczałkowice on the Vistula, Rożnów on the Dunajec and Tresna on the Soła, thanks to which reasons for the differences in these changes were determined. For this purpose, data on the volume of the suspended load was used. Diversity in its transport is mainly caused by the presence of damming structures. Correlation of morphological and hydraulic indicators was carried out, preceded by the identification and characteristics of all transverse and longitudinal structures located in catchments upstream of individual reservoirs. Analysis of the geological structure, as well as the structure of land use in the basins of the reservoirs, was also performed. The obtained results allowed for the preparation of recommendations for further work, allowing, among other things, an increase in water retention. The key factors for maintaining the capacity of retention reservoirs were defined, which may be useful in national plans or programs in the field of counteracting the effects of drought or flood protection. © 2023 by the authors.},

Loss of reservoirs’ storage capacity has a significant impact on the management of their water resources, including flood protection and counteracting the effects of drought and the possibility of producing electricity. The paper presents changes in the capacity of 47 reservoirs in Poland that have the status of key objects of protection against floods and hydrological drought. Based on the collected, unpublished data, the changes in capacity from the beginning of the reservoirs’ existence to 31 March 2021 were calculated, which allowed us to determine the total amount of lost capacity and the pace of the processes taking place. From the beginning of operation (average operation time 48 years), the capacity has decreased by about 5%, which means that almost 200 million m3 less water is stored. Detailed analyses of the lost capacity also allowed for an illustrative presentation of forecasts for further changes in the short and long term. The results obtained represent a unique contribution to future national strategies for the management of sediment and reservoirs’ flood reserve and reduction of drought. The presentation of this problem seems to be important also in the context of climate change. © 2021 by the authors. Licensee MDPI, Basel, Switzerland.},

In its history Paprocany reservoir overcame numerous hydrotechnical changes influencing its present functioning. Also, its current state is significantly influenced by saline water from the coal mine (5 g L−1 of chlorides and sulphates) and biogenic elements in recreational area (about 70 mg L−1 of chlorate and to 1.9 mg L−1 Kjeldahl nitrogen) and in sediments (222.66 Mg of Kjeldahl nitrogen; 45.65 Mg of P; and 1.03 Mg of assimilable phosphorus). Concluding, the best solutions to improve the Paprocany reservoir water quality comprise: increasing alimentation with water and shortening the water exchange time, restoration of the 19th century water treatment plant, and wetlands and reed bed area revitalization.

abstract = {Reservoirs are formed through the artificial damming of a river valley. Reservoirs, among others, capture polluted load transported by the tributaries in the form of suspended and dissolved sediments and substances. Therefore, reservoirs are treated in the European Union (EU) as "artificial" or "heavily modified" surface water bodies. The reservoirs' pollutant load depends to a large extent on the degree of anthropogenic impact in the respective river catchment area. The purpose of this paper is to assess the mutual relation between the catchment area and the reservoirs. In particular, we focus on the effects of certain land use/land cover on reservoirs' water quality. For this study, we selected twenty Polish reservoirs for an in-depth analysis using 2018 CORINE Land Cover data. This analysis allowed the identification of the main triggering factors in terms of water quality of the respective reservoirs. Moreover, our assessment clearly shows that water quality of the analysed dam reservoirs is directly affected by the composition of land use/land cover, both of the entire total reservoir catchment areas and the directly into the reservoir draining sub-catchment areas. © 2020 by the authors.

abstract = {A detailed sedimentological study of the Lower-Middle Muschelkalk (Middle Triassic) carbonate succession exposed at the "Stare Gliny" quarry near Olkusz (Krakow-Silesia region; southern Poland) revealed numerous vertebrate remains within its lowermost sedimentary unit. This 7-m-Thick package onlaps a gently-inclined surface of a paleoisland made of the Devonian (Givetian) dolostones, and was deposited during a transgressive phase of the second Middle Triassic transgression onto the southern Poland. The package consists largely of: 1) unfossiliferous dolosiltites and fine-grained dolarenites, the tops of which commonly contain root molds and small-scale karstic forms; 2) breccias (minor conglomerates) with lithoclasts of Givetian dolostones; 3) dolocretes; and 4) dolomitic shales. This lithofacies association represents a restricted lagoon which experienced longer periods of emersion. A minor occurrence of cryptalgal laminites reflects only temporary sedimentation in the intertidal zone of a tidal flat. The bone fragments occur within all types of lithofacies, but the macro- scopically distinguishable specimens have been found exclusively in the dolocretes. The poor preservation and advanced disarticulation of bones hinder unequivocal assessment of their affinity. The small size of hones suggests that they represent prolucertiforms (perhaps juvenile Macrocnemus,) or other small archosauromorphs similar in sizes to Protorosaurus or Czatkowiella whose remains were found in the 1950s within cave deposits, in the same outcrop. Macrocnemus widely inhabited Middle Triassic lagoons and tidal flats across Paleo-Europe and thus seems to fit well to the peritidal setting surrounding the "Stare Gliny" paleoisland. The bone-hearing package occurs 30 metres below the 5-m-Thick oncolitic package that is widely regarded as a correlation horizon over the entire Krakow-Silesia region, and 15 metres below the sequence boundary marking the top of the Gorazdze Beds in the Opole region and the Olkusz Beds in the Krakow-Silesia region. On the basis of these correlations, a conclusion can be made that the vertebrate assemblage is Bithynian/Pelsonian (middle Anisian) in age.},

Both lakes are characterized by largely different physico-chemical regimes; Batur Lake is located in an area that is currently volcanically active, unlike Bratan Lake. The latter is much smaller and shallower than Batur Lake. The concentration of pollutants in the Indonesian equatorial lakes is largely unknown, and the impact of both biological and geothermal processes on their distribution requires attention. This study shows that the concentrations of cations (Na+; K+; Mg2+; Ca2+), anions (SO42-; F-; Cl-; Br-) and trace elements (Li; B; Al; V; Cr; Mn; Co; Ni; Cu; Zn; As; Se; Rb; Sr; Mo; Cd; Sn; Cs; Ba; Pb; U; Be; Ag; Sb; Tl; Bi) differ greatly between both lakes. Most chemical parameters determined in volcanically influenced Batur Lake were tens to hundreds times higher than in Bratan Lake, and in the case of trace metals, the ratios of the two lakes' concentrations reached several hundreds. This study also compared the composition and concentration levels of organic compounds in both lakes, such as fatty acids, halocarbons and esters. On the other hand, the content of organic chemicals in the lakes also results from biological activity by phytoplankton, zooplankton and bacteria. © 2015 by the authors.},

abstract = {Agricultural activity results in water pollution from nitrogen and phosphorus compounds. Increased concentrations of nitrogen compounds pose a threat to animal and human health. The purpose of this study was to determine the impact of agriculture in a catchment basin on the level of surface water pollution from biogenic compounds. Spatial analysis of the land cover was conducted using GIS and was based on data from the Corine Land Cover databases. The study results indicated that high concentrations of nitrogen and phosphorus compounds existed in the surface waters. In the surface water, high concentrations of biogenic compounds occurred in both primarily agricultural catchments and in urbanized drainage areas. Water may be regarded as eutrophicated or at high risk of eutrophication because the majority of the nitrate concentrations at the monitoring sites exceeded a limit of 10 mg·dm-3 NO2- 3. Inadequate farming practices and poor sanitary conditions on farmsteads result in the leaching of biogenic substances into the water. To protect water from biogenic pollutants, it is necessary to adopt a new approach to fertilizer use and to improve the sanitary conditions of agricultural properties, which can be achieved by, among other things, the installation of drainage systems in rural areas. Our recommendations include the protection of river valleys as follows: by stopping deforestation, by preserving natural riparian vegetation, and by reducing the volume of intensified agricultural activity or introducing so-called “precision farming.” © 2015, HARD Publishing Company.

abstract = {Monitoring contamination in river water is an expensive procedure, particularly for developing countries where pollution is a significant problem. This study was conducted to provide a pollution monitoring strategy that reduces the cost of laboratory analysis. The new monitoring strategy was designed as a result of cluster and regression analysis on field data collected from an industrially influenced river. Pollution sources in the study site were coal mining, metallurgy, chemical industry, and metropolitan sewage. This river resembles those in other areas of the world, including developing countries where environmental monitoring is financially constrained. Data were collected on variability of contaminant concentrations during four seasons at the same points on tributaries of the river. The variables described in the study are pH, electrical conductivity, inorganic ions, trace elements, and selected organic pollutants. These variables were divided into groups using cluster analysis. These groups were then tested using regression models to identify how the behavior of one variable changes in relation to another. It was found that up to 86.8% of variability of one parameter could be determined by another in the dataset. We adopted 60, 65, and 70% determination levels (R2) for accepting a regression model. As a result, monitoring could be reduced by 15 (60% level) and 10 variables (65 and 70%) out of 43, which comprises 35 and 23% of the monitored variable total. Cost reduction would be most effective if trace elements or organic pollutants were excluded from monitoring because these are the constituents most expensive to analyze. © American Society of Agronomy, Crop Science Society of America, and Soil Science Society of America.},

abstract = {This article presents hydrological aspects of a renaturization plan for a river valley that has been significantly transformed as a result of human impact. A section of the Szarlejka River valley located at the border of the cities of Bytom and Radzionkow was used for this purpose. The hydrographic conditions of the area under consideration have been significantly altered due to human action. These transformations are the result of systematic residential and industrial infrastructure development, which has been accompanied by industrial waste disposal. Underground coal mining in the area has caused subsidence and discharge of saline mining waters to rivers. The Szarlejka is considered one of the most polluted rivers in Silesia Province (Polish: wojewodztwo ślaskie) and all of Poland. The primary objective of the renaturization plan is to improve abiotic conditions and water status. This plan is based on the analysis of all accessible data, including archival maps and field work. Hydrological and hydrotechnical renaturization actions are proposed for the Szarlejka River valley that cover the elements, structures, and facilities, of which the mere presence brings the waters closer to their natural state (barrages inhibiting erosion; connections allowing for the circulation of aquatic organisms). The proposal also includes building astatic reservoirs, creating oxbow tanks in retained sections of the old river bed, and building a pond with a wetland and an island. The restored structures will affect abiotic and biotic conditions, consequently influencing the water recovery process with the aim of bringing it closer to its natural state. For the purposes of the planned renaturization, a geographic information system (GIS) was created, enabling digital map generation, database creation, and calculations.},

abstract = {The aim of the study is the analysis of runoff and water quality changes in the Upper Oder River Basin above the Krapkowice gauging station (catchment area A = 10 720.6 km2). The issue of water quality is of particular importance to Poland, which has comparatively poor water resources compared with many countries of the European Union (EU). What is more, large pollutant loads in the upper course of the Oder pose huge problems for water consumers and users in its middle and lower course (including Germany) and pollute the Baltic Sea. Changes in 7 indices of water pollution, including BOD5 and COD (synthetic indices), sulphates, chlorides and suspended matter (mineral substances) and nitrates and phosphates (biogenic substances), were investigated for 8 monitoring sites. The study spans the period before and after political transformation in Poland and the Czech Republic, which significantly altered the economies of these countries. In addition, the patterns of runoff changes were analysed at 3 gauging stations: Chałupki, Krzyżanowice and Miedonia, which were also water quality monitoring points. The analysis encompassed 2 periods: 1970-2000 and 1991-2000. The results demonstrated that poor water quality in the Oder improved significantly during the 1990s, as the result of closure of many industries and plants, improvement of sewage treatment and noticeable increases in runoff causing greater dilution of pollutants. As the EU Water Framework Directive is implemented, better water and sewage management can be expected that will contribute to further improvement of water quality in the Oder. However, problems that remain to be solved are the issues of saline mine waters and surface washings and the long-term accumulation of many hazardous substances in bottom sediments in rivers and reservoirs. © 2007.},

abstract = {The research area was the Upper Oder River Basin: from its springs to the Koźle gauge-station. The total area of the territory studied was 9,173.6 km2. Field observations were carried out in the hydrological years: 1996, 1998, 1999 and 2000. In the course of field research in the Polish part of the river basin, 18 springs were chosen for periodical observations which were made at monthly intervals. In the Czech part, the study comprised nine springs, which are part of the Czech Hydrometeorological Institute (CHMI) observation network. Yields of the researched springs vary. From the time series measurement of spring yields, for most of the objects the yield is predominantly influenced by thaw water alimentation, and to a lesser degree by rainwater. Most of the researched springs have the thaw-rain regime. The Upper Oder River Basin is predominated by springs with yields of up to I dm3. s-1.},
