Opis:
On Earth water is an irreplaceable asset, and an estimate of its resource capacity is necessary. The improper selection of indicators of water resources can lead to the underestimation or overestimation of the actual resources present. Incorrect assessments of water resources contribute to the improper completion of necessary water management tasks, thereby failing to satisfy the needs of different water users such as industry, agriculture and forestry, inland water navigation, tourism and recreation and the general population for the purposes of municipal water use. This article discusses the advantages of utilizing Earth Observation technology for estimating water resources in Poland. Despite the large amount of water on Earth, decades of wrongly pursued water management have led to a critical point in maintaining this valuable resource. According to actual estimations, there are enough fresh water resources in the world; the problem is the uneven distribution and pollution of these resources, especially in the case of surface water. Currently, Poland, in comparison with other European countries, is classified as a country with very little water resources. It is important, however, that a thorough evaluation using the latest measurement technologies is conducted, particularly for groundwater resources in deep layers of the lithosphere. The proper assessment of water resources requires knowledge of the hydrogeological conditions within each of the catchments of the analyzed area. International data sets are mostly incomplete and heterogeneous, which makes the comparison of data of several years difficult and often leads to mistakes. While analyzing Polish water resources several factors should be taken into account, including: the amount of rainfall, the amount of water in rivers, lakes and groundwater, and the above-mentioned factors affecting the measurement of the amount of disposable water resources. This article is an introduction to the broader analysis of water resources in Poland and an exploration of the issue from a different perspective.

The paper presents a hydrological cycle that takes place in nature and addresses the concept of water resources and the methods of their measurement as well as the shortage of water resources. In the ensuing discussion, the paper assesses those conditions by the continents and regions, pointing out the difficult situation in Northern Africa, the Middle East and Central Asia. Further, it presents the investigation of the correlation between the volume of GDP and the particular features of water management within the continents. The results of calculations show differences, yet there is a clear correlation between the number of population, the water consumption and other indexes of water management. The paper ends with the conclusion that there is basically no shortage of water resources within the world economy, yet there is more and more acute crisis in water supply on the regional scale due to the insufficient water supply and sewerage infrastructure, improper economic policy and environmental policy, and poverty among large groups of population.

Potable water is a commodity and basic necessity of life for which metropolitan areas and adjacent areas are to pay. Water from Manila Waterworks and Sewerage System (MWSS) has also become a problem considering the low water supply coming from their sources. Because of El Nino phenomena and other problems of the water system, rationing Metro Manila was implemented. This descriptive study aimed to assess the performance and effectiveness of community water supply management in terms of the quality of water such taste, odor, color, sediments, service and cost and design water safety plan for the community. Purposive sampling was used to determine the participation of the knowledgeable homeowners of Karangalan Village in the province of Rizal. Some interesting insights of the study are: Potable water is the water delivered to the homeowners. However, there are sediments and brownish color observed in the water due to pipe corrosion. In terms of service, the performance of the water system delivered to the homeowners is acceptable based on the volume delivery, accessibility, availability, promptness, and reliability. Homeowners who use potable water are satisfied in terms of its efficiency, effectiveness, user-friendly, promptness and expandability. Water safety plan is an integral part of the whole planning process and helps improve the management of Karangalan village water supply and may be undertaken or updated at any time

Opis:
The main target of this paper is to develop the hypothesis that water intake fees can be an efficient tool for the management of water consumption in Poland. The sample used in the research consists of 600 municipal water operators with a market share over 80% in the municipal sector. The analysis comprises several tasks: firstly – the investigation of the relation between water intake fees and the structure of the costs of water provision; secondly – the investigation of the influence of fees on unit prices and a review of their changes over the last decade; and, thirdly – the analysis of demand elasticity in order to estimate demand reaction. The results obtained give an estimation of possible savings in water usage in Poland that would result from changes in the system of water intake. The analysis includes all the mechanisms of fee reductions, or exemptions for certain purposes, of existing water intake in Poland. This analysis compiles, compares and processes incremental results from several pieces of research led by the author over the last 10 years for the Ministry of the Environment the National and Regional Water Boards and also for the Institute for Meteorology and Water Management. Research was focused on the economic analysis of water usage from a more general view, however, water intake fees are taken into account in these papers, although not as separate targets for investigations.

Opis:
Worldwide, annual water demand has been increased for different uses. This can be attributed to population expansion and the accompanying need to satisfy their water needs for domestic, agricultural, and industrial purposes. The situation has been becoming worst due to vulnerable and inefficient water supply systems. Rainwater harvesting (RWH) has been proved to be a sustainable option in solving the on-ground water shortage to a great extent. India has been facing the wrath of a water crisis for about a decade or two. The potential of RWH in India is more due to its geographical location and landscape. This paper aims at studying the impact of adopting RWH techniques as an artificial recharge option to evaluate groundwater table in the Joda town of India by analyzing the difference in water levels of the township throughout the past decade (2009-19). The study revealed the increase in the underground water level of the study area and established that RWH systems are crucial in arid regions to a large extent.

Water resources are basic condition for survival and development of mankind on certain territory. The quantity of water resources in community depends on geographical location and certain hydro-geological, hydro-logic and hydro-biologic conditions on certain area. It means, that water resources are measurable and strictly defined. Due to consumption of water to different purposes (municipal entrepreneurship, industry, agriculture), the quantity of water resources may be depleted both quantitatively and qualitatively. The local self-government, according to provisions of law has possibility and obligation to pursue a policy of providing ecological security for its citizens. Creation of civic consciousness among the citizens of communities is also an important factor for providing the ecological security.

Opis:
The paper presents the problem of the growing water deficit and the possibility of sustainable development of water resources in rural areas of Central and Eastern Europe (using the example of Poland). It is estimated that the amount of resources in this region is reduced by about 70% compared to the average for Europe. In drought periods it comes to limitation of economic activity, including agriculture. Particular attention was paid to the necessity to extend landscape, underground, and snow retention, as an alternative to dams, which are currently the most popular in lower-order catchments. It has been shown that the construction of small agricultural reservoirs is not always preceded by adequate consultations and pre-design studies, which may result in financial losses and legal problems. Simultaneous use of many alternative forms of retention should be more effective than the implementation of reservoirs. In addition, increasing the hydraulic roughness of the catchments slows down the outflow of products of erosion and contributes to the protection of surface retention structures (maintaining natural and economic usefulness of reservoirs).

Opis:
The availability of water in adequate sufficient quantity and quality is the most important factor in maintenance of life and human activity. Surface water as easily accessible resources per citizen in Poland should not be compared to other countries of the European Union. Podlasie is a lowland region, which is dominated by vast plains occasionally varied by low hills with gentle slopes. Natural lakes occurring sparsely are heavily overgrown or completely restated as a result of moor succession. The storage of natural hollows which store water resulted in the construction of artificial dam reservoirs, allocated primarily to water accumulation. Lowland development of small retention mainly consists of increasing the retention capacity and prevention of drought and floods, while maintaining and supporting the development of the natural landscape. This article presents the characteristics of selected major small water reservoirs in Podlasie. Characterized and evaluated the susceptibility of dam reservoirs degradation: Czapielówka, Korycin, Otapy-Kiersnówek, Repczyce, Zarzeczany. To evaluate the susceptibility of degradation there was applied Schindler factor, which is the ratio of the accumulated surface water reservoir and its catchment area to the volume of the reservoir. In addition, the influence of development of catchment management and the degree of degradation has been evaluated. Realising aware of the limitations of the size of the water resources is suggested to take appropriate action to alleviate the degradation of artificial reservoirs.

Od 2016 r. Najwyższa Izba Kontroli przeprowadziła kilka kontroli dotyczących zasobów wodnych i odprowadzania ścieków, wskazując na liczne nieprawidłowości i zagrożenia związane z nieprawidłowym gospodarowaniem w tym obszarze. Racjonalnemu wykorzystaniu wody, a także jej ochronie w Polsce miały sprzyjać w ostatnich latach liczne inwestycje. W 2020 r. nakłady na środki trwałe służące gospodarce wodnej wyniosły łącznie 2666 mln zł, z czego najwięcej przeznaczono na ujęcia i doprowadzenia wody, budowę i modernizację stacji uzdatniania oraz zbiorniki i stopnie wodne. W ostatniej dekadzie odnotowano poprawę w dostępie do wody pitnej oraz usług sanitarnych, jest ona jednak najbardziej odczuwana na terenach miejskich. Dostrzegając wagę efektywnego gospodarowania zasobami wodnymi, zwłaszcza w sytuacji słabiej rozwiniętej infrastruktury wodociągowej i kanalizacyjnej na terenach wiejskich, Najwyższa Izba Kontroli przeprowadziła badanie, którego ustalenia wskazały na problemy w gospodarowaniu przez przedsiębiorstwa wodociągowe oraz niewystarczające działania podejmowane w celu minimalizowania strat i zapewnienia właściwej jakości dostarczanej wody. Szczegóły przestawiono w artykule.
A decrease in the level of water safety has been observed in recent years. Changes in climate (that have, for example, resulted in drought), insufficient water retention, demographic changes and activities in many areas of economy affect the availability of water resources. In the light of the limited size of these resources, steps taken to use them practically play an increasingly vital role. The importance of proper management of water resources is underlined in the context of sustainable development. Disparity between urban and rural areas in terms of progress in achieving the goals of sustainable development (related to water resources management), or less access to water supplies and sewage infrastructure in villages, reflect the need to assess the adequacy of actions taken by water companies. The Supreme Audit Office carried out an audit of the effectiveness of water resource management in rural areas. Its results show numerous irregularities and neglects resulting in significant water losses and problems in terms of water quality. The article highlights the most important findings of the audit in the context of the protection of water resources.

Opis:
The exceptionally high spatial-temporal variability of the river runoff and the significance of its transboundary component considerably worsen the problem of the water supply of the republic. Due to the disadvantageous geographical location in the lower reaches of transboundary river basins, the Republic of Kazakhstan is largely dependent on water economy activities taking place in neighbouring countries. In the article the modern change of the resources of river runoff in Kazakhstan, taking into account climatic and anthropogenic influences is considered. For the assessment of the impact of economic activities on the river runoff and changes in climatic-related runoff, the complex of integral methods was used, and appropriate methodologies were developed. The obtained results of the modern influence of a complex of factors, as well as their significance for the future (till 2030), can be used for the development of scientifically based solutions for sustainable management and protection of water resources. An assessment of the anthropogenic activity of this study shows that the water resources of the river runoff of the Republic of Kazakhstan have decreased by 16.0 km3∙y-1. According to our forecasts, there will be a further decrease in the water resources of the republic due to the expected decrease in transboundary flow to 87.1 km3∙y-1 by 2030, in dry years less than 50.0 km3∙y-1. We propose a set of measures to prevent the negative impact of possible reduction of river runoff resources in the future in the water basins of Kazakhstan.

Opis:
The objective of this work is the agroecological substantiation of the use of treated wastewater for irrigation of agricultural land. As the result of the experimental research, it was established that the soil microflora plays an essential role in strengthening or weakening the biological activity of soil. Therefore, with an irrigation rate of 250 m3/ha of wastewater, a 1.5 times increase in the number of microbiota colonies is observed on average both in hog farms and cattle breeding complexes; with a rate of 350 m3/ha – a 2-fold increase; with a rate of 450 m3/ha – a 3.5–4-fold increase. An increase in nitrifying soil features has also been observed. Thus, if the value on the control in the soil layer from 0 cm to 60 cm is 27.2 mg of nitrate per 1 kg of arid soil, in the version with wastewater irrigation it reaches 46.7 mg. According to the research results, the use of defecate, the waste of sugar production, in the treatment of wastewater of livestock farms does not have a negative agroecological impact on the soil. Therefore, the method of wastewater treatment of pig-breeding complexes and farms can be recommended for use in irrigation reclamation, which includes treatment of wastewater with burnt defecate in the dose of 50–200 mg/dm3, with the pH value varying in the range of 7.5–8.5. After settling-out of the obtained mixture in settlers, it is divided into a transparent liquid fraction and the sediment, i.e. an organomineral fertilizer. Afterwards, the fluid body is fed to irrigation of agricultural land, and its excess is discharged into waterways and reservoirs. The sediment is fed to the vortex layer equipment with mobile ferromagnetic particles or thermolized, where their complete disinfection takes place.

Opis:
Both China and India are suffering from a set of grave water crises involving water scarcity, imbalance in both space and time, low water use efficiency and rampant water pollution. Sino-Indian relations might suffer due to a 'concern' over the so-called 'diversion of the Yarlung Zangbo' and water resource development in Tibet. However, the two neighbours need to cultivate sincere water cooperation covering joint research in hydro-technology and water policy, business-to-business engagement and international cooperation on water issues. This will effectively help address the water challenges of both countries. The paper aims to outline the major water security challenges inside both China and India as well as potential conflict over water between them on the one hand, and to explore possible water cooperation between the two neighbours on the other. The major hypothesis is that domestic water security challenges for both China and India are real and severe, while the so-called water conflict between them is largely a played-up story. In this sense, the paper rejects the zero-sum realist framework and calls for a non-zero-sum liberalist approach for a better understanding of the water dynamics between China and India.

Opis:
The study covered water resources of two mountain streams in the Polish Carpathians. These were the Biała Woda and Czarna Woda streams, the catchments of which are adjacent to each other. Water flows in both streams were measured during the hydrological years from 2006 to 2020. Next, water outflows from the catchments were calculated. The study aimed to determine differences in the water resources of those catchments in a very small mountainous area. The study showed quantitative similarity in water resources in the entire multi-annual period but at the same time large differences in shorter periods. Instantaneous and daily outflows showed the largest differences, but differences in annual outflows of up to 20% were also recorded. Therefore, hydrological data from operational cross-sections to assess water resources of neighbouring uncontrolled watercourses should cover multi-annual mean values. It was found that during periods of increased runoff (from melting snow or precipitation), the outflow from the Biała Woda catchment was much larger, while during rain-free periods, the outflow from the Czarna Woda catchment prevailed. All short-term flood like outflows were at least several tens of per cent higher in the Biała Woda catchment. The higher retention capacity of the Czarna Woda catchment can be attributed to the land use (mainly forest areas). The results can be used for modelling catchments of similar parameters and determining their retention capacity.

In this sense, the knowledge of the morphometric parameters of the river takes on special importance. Morphometric analysis helps in understanding the geo-hydrological characteristics of a river basin. Various authors point out that the morphometric analyses of a drainage watershed demonstrate the dynamic equilibrium that has been achieved due to the interaction between matter and energy. The analysis of morphometric parameters also facilitates and helps to understand the hydrological relations of the basin. This paper deals with the morphometric analysis of sub-basins in the Klina River basin which is located in the northeastern part of the Dukagjini depression. To determine the morphometric parameters in the Klina River basin, the digital relief model from the Advanced Land Observation Satellite (ALOS) platform with a resolution of 20 × 20 m and the ArcMap 10.5 software were used. The results reveal that the total number of streams is 753 of which 602 are 1st order streams, 119 - 2nd order, 23 - 3rd order, 6 - 4th order, 2 - 5th order, and 1 - 6th order streams. The mean bifurcation ratio is 3.81, drainage density is 1.52 km∙km-2. The data and information presented in this study will be helpful and interesting in the plan of the management of Klina River basin which covers an area of 477 km2 within which is estimated to live about 100,000 inhabitants.

Opis:
The main purpose of this study is to determine the optimum water consumption for achieving water savings and obtaining good yields in cotton production, which has been expanding in Central Asia and Turkmenistan since the 1960s. In the last few decades, water resources in the region have been difficult to access, due to the expansion of agricultural activity and population growth. The oscillation of the amount of water released from dams of the Amudarya River to obtain energy for the upper countries in the winter season has been causing crises in countries of Central Asia. An experiment was carried out in an agricultural field at a cotton research centre in the Yolöten district of Turkmenistan. The experiment led to the observation that it is possible to achieve higher efficiency and lower water consumption in cotton production. At the same time, the water savings that can be achieved as a result of using the drip irrigation method in cotton production throughout the country have been calculated. The calculations have provided the basis for recommending irrigation as a solution to the problems in question.

Opis:
Stosunki hydrologiczne w cieku Jeziorka, położonym w dolinie Odry, są kształtowane warunkami fizjograficznymi i meteorologicznymi oraz stanami wody w Odrze. Koryto Odry poniżej jazu w Brzegu Dolnym charakteryzuje się systematycznie postępującą w dół rzeki erozją liniową, co oddziałuje na stany wody w rzece i przepływy w Jeziorce. W pracy przedstawiono ocenę zasobów wód Jeziorki na odcinku Głoska-Brodno 1 w latach 1971-1989 i 1995-2010. Analiza zależności przyrostu przepływów ΔQ na odcinku Głoska-Brodno 1 od różnicy stanów wody ΔH w Odrze i Jeziorce wykazała, że dla różnicy stanów ponad 2,0 m średnie roczne i półroczne przepływy w przekroju dolnym (Brodno 1) są mniejsze niż w górnym (Głoska).
Hydrological conditions in the Jeziorka stream situated in the Odra River valley are shaped by physiographic and meteorological conditions and the water levels in the Odra River. The Odra below the dam in Brzeg Dolny is characterised by steadily progressing downstream linear erosion chich affects water stages and flows in the Jeziorka stream. The paper presents an assessment of water resources in Głoska-Brodno 1 section of the Jeziorka stream in the years 1971-1990 and 1995-2010. Analysis of the relationship between flow increments in the section Głoska-Brodno 1 (ΔQ) and the differences of water levels in the Jeziorka and the Odra Rivers (ΔH) showed that for ΔH › 2.0 m, mean annual and semi-annual flows in the lower cross-section (Brodno 1) are smaller than those in the upper one (Głoska)

Opis:
Climate change has been observed for many years, being a worlwide source of concern. Reoccuring droughts and changes in precipitation in some regions of the world prompted research into the influence of climate change on the drying up of water. The following study analyses the dependencies between climate change and the drying up of rivers. In the introduction a history of climate change is presented followed by an analysis of global water reasources: their availability, changes in precipitation and their causes and effects. The third chapter deals with the influence of the observed changes on the availability of freshwater in the world. The study ends with the conclusion that the impact of climate change on the drying up of water remains unclear, with the bigger problem being the impact of these changes on the reduction of the quality of water, a fact that may lead to many global problems.

Opis:
The amount of water required to support a river ecosystem in proper condition are of particular importance in the areas of high natural value. The hydrological threats for the protected areas are region-specific and vary from region to region. The local hydrological conditions depend largely on the temporal and spatial variations of the hydrologic cycle, of the main components and physiographic conditions on site. Future climate change is projected to have a significant impact on the hydrological regime, water resources and their quality in many parts of the world. The water-dependent ecosystems are exposed to the risk of climate change through altered precipitation and evaporation. Investigating the current climate changes and their hydrological consequences are very important for hydrological issues. This analysis may be a very important foundation for determining the causes observed in the recent period of anomalous growth – both hydrological and climatic. The aim of the research is to assess the effect of projected climate change on water resources in lowland catchment the Narew River in Poland. The hydrological reaction to climate warming and wetter conditions includes changes in flow and water level. This paper describes the directions of changes climatic and hydrological conditions and the impact of climate change on the Narew River. The data such as: daily air temperature, precipitation obtained from the Bialystok climate station located within the Narew river and hydrological data such as water flows and water states observed in water gauges were used for the analysis of climate variability and their hydrological consequences. The results show a significant decrease in winter outflows in river, as well as a delayed increase in the spring melt flow. It has also been observed that this is the initial phase of changes in maximum water levels and maximum flows.

Opis:
The purpose of the paper is to analyze the spatial variability of precipitation in Poland in the years 1981–2010. The average annual rainfall was 607 mm. Precipitation in Poland is characterized by high spatial and temporal variability. The lowest annual precipitation was recorded in the central part of the country, where they equaled 500 mm. The highest annual precipitation totals were determined in the south, equaling 970 mm. The average precipitation in the summer half-year is 382 mm (63% of the annual total). On the basis of data from 53 climate stations, maps were made of the spatial distribution of precipitation for the period of the year and winter and summer half-year. The kriging method was used to map rainfall distribution in Poland. In the case study, cross-validation was used to compare the prediction performances of three periods. Kriging, with exponential type of semivariogram, gave the best performance in the statistical sense. Their application is justices especially in areas where landform is very complex. In accordance with the assumptions, the mean prediction error (ME), mean standardized prediction error (MSE), and root mean-square standardized prediction error (RMSSE) values are approximately zero, and root-mean-square prediction error (RMSE) and average standard error (ASE) reach values well below 100.

Opis:
W kopalniach, oprócz tradycyjnie wydobywanych surowców mineralnych, występują jeszcze inne zasoby, tj. wodne i energetyczne, które w ogóle nie są wykorzystywane, lub też mają praktyczne zastosowanie w niewielkim stopniu. Pozyskiwanie wymienionych zasobów mogłoby poprawić efektywność ekonomiczną kopalń czynnych lub przedłużyłoby okres aktywności kopalń zamykanych. W artykule omówiono potencjalne możliwości wykorzystania zasobów energetycznych, pozostających poza sferą podstawowej działalności górniczej, związanej z wydobyciem złóż węgla kamiennego, ale także z eksploatacją różnorodnych surowców użytecznych. Podjęto również aspekt szerszego zagospodarowania kopalnianych wód podziemnych. Nawiązano do skutków likwidacji kopalń węglowych, na przykładzie Wałbrzyskiego Zagłębia Węglowego. Podkreślono ważność i aktualność podjętej problematyki. Przedstawione propozycje mogą stanowić wkład w urzeczywistnienie zasady zrównoważonego rozwoju, poprzez koncentrowanie się na trzech jego wymiarach – ekonomicznym, ekologicznym i społecznym. Jednocześnie byłby to sposób na zrównoważone zarządzanie środowiskiem wodnym na obszarach antropopresji, na terenach przemysłowych i post-przemysłowych, dla celów pozyskiwania wody, poprawy jej jakości oraz skorzystania z lokalnych źródeł energii, takich jak: ciepło i energia związana z potencjałem wodnym. Ponadto wskazano na możliwość magazynowania energii, co jest niezwykle ważne w dobie intensywnego rozwoju niekonwencjonalnych źródeł energii elektrycznej (farm wiatrowych, źródeł solarnych, elektrowni wodnych etc.), określanych wręcz jako źródła chimeryczne, gdyż ich cechą jest nieregularna praca.
In addition to the traditionally mined mineral resources, water resources and energy are still present in the mines. Those resources are not used at all, or are intended for practical use, but to a lesser degree. The acquisition of these resources could improve the economic efficiency of active mines or prolong the period of activity of the closed mines. The article discusses the possibilities of using energy resources which are outside the sphere of the core business of mining and have taken a broader aspect of the development of underground water from mines. The proposals constitute a contribution to the implementation of the principles of sustainable development by focusing on three of its dimensions - economic, environmental and social. At the same time it would be a way for the sustainable management of the water environment in the areas of anthropopressure, in industrial and post-industrial areas, for the purpose of collecting water, improving water quality and the use of local energy sources, such as heat and energy associated with potential water. The possibility of energy storage, which is extremely important in the era of an intensive development of unconventional sources of energy (wind farms, solar sources, hydroelectric, etc.), the characteristics of which are irregular, referred to simply as chimeric sources, also exists.

Opis:
The paper examined water resources insecurity arising from climatic change and variability, coupled with increased population and economic development in in Yewa basin, with a view to understanding the relationship between climatic variables and hydrological parameters operating within the basin. Thus, the study entails assessment of the effects of climate change and variability on water resources and its implication on both the physical environment and the hydrological regime, using the water evaluation and planning (WEAP) system model. Data employed included water supply and demand for Domestic, Commercial, Industrial and Agriculture, as well as climatic data (rainfall and Temperature) and runoff. As revealed by the Scenario fabrication, 45.24% of the annual water requirement within Yewa Basin is not met, with water potentials of Annual mean discharge of 3682.46 m3/s (±830.1) and Annual mean rainfall of 1106.26m (±475.25), and with coefficients of variation of 40.88 and 73.73, respectively. This deficit calls for an appropriate water resources management mechanism to be put into use in Yewa Basin.
