    Opis:
    Water resources are essential for sustaining life forms, food production, socio-economic development, and for general well-being. Water is intrinsically linked with several perspectives of human rights like right to life, right to food, right to self-determination, right to adequate standard of living, right to housing, right to education, right to health, right to take part in cultural life, right to suitable working conditions etc. Yet, human rights to water remains imperfectly defined. Global water consumption is doubling every 20 years, more than twice the rate of human population growth. The growth in water consumption is highest in the agricultural and industrial areas, where the resources to buy water are readily available with rich farmers and industrialists. Potential human right issues can arise from lack of safe water. Construction of dams can lead to ecosystem imbalances and degradation of the quality of human life, specially the livelihood of the indigenous and tribal populations. To solve the growing water crisis, one of the possible solutions that has been proposed and has been implemented is water privatization, which majorly considers water as a profitable commodity. Water pricing and privatization will inevitably increase the price of the major crops and vegetables all around the world, which, in turn, can adversely affect food security. Community based water management policies such as rainwater harvesting, check dam construction, sustainable watershed management, integrated river basin management and irrigation efficiency can be sustainable solutions of water crisis, which also can respect the human right issues as well.

    Opis:
    The aim of the article is to present the importance of building dams and water reservoirs in the politics of the last Emperor of Ethiopia, Haile Sillasie I. The article concentrates on the propaganda aspect of this activity. The article presents the problem in a broader historical context, also referring to the periods after the fall of the Empire, thus trying to prove the continuity of the importance of the problem of water in Ethiopian politics. The main source used is ‟Ethiopian Observer”, published during Haile Sillasie’s reign, which promoted a positive image of the changes taking place in Ethiopia during this period.

    Opis:
    In recent years, a significant growth in the population of the European beaver Castor fiber L., both in Poland and around the world, has been observed. Beavers significantly transform the natural environment around the sites where they occur. Therefore, it is important to accurately recognize the colonization patterns of new territories by the European beaver and to gain knowledge about the longevity of populations in already occupied areas. This applies especially to areas of natural value, including protected areas. Fieldwork carried out in the spring of 2021, provided information on the distribution of the European beaver and number of individuals in the Magura National Park (MNP) in the Beskid Niski, an arboreous mountain range in southern Poland. The collected data were compared with similar mappings conducted in this Park in 1996 and 2010. This allowed us to characterize the change dynamics of the beaver population in the MNP area and to describe the changes in spatial distribution of sites inhabited by beavers. During the period of 1996-2021, the population of the European beaver increased from 23-26 to 64 individuals in the study area, with a maximum of 68 in 2010. Beaver colonization of ever smaller watercourses draining higher-located catchments and a change in the characteristics of beaver-inhabited sites have been observed. The average number of dam structures within one site as well as site length have increased. Furthermore, the dominant dwelling type has changed from burrows and open-water lodges to bank lodges, which combine characteristics of the two former. We estimate that the period when beavers migrated further up along the watercourses in the studied area was in the years 2010-2021.

    Opis:
    The last four decades weather forecasting data marks the precipitation declination and increase dry years, in addition to the desertification migration on the west and northwestern Mosul city. This led to studying the Al-Shor Wadi area to try to make use of the karstic spring water flow through it and to harvest the rainfall flow water. These need to select the best site to construct a dam taking into consideration the geological and geotechnical characteristics of both dam site and lake behind. The dam site appears to be appropriate relying on the large thickness and frequencies of the marl bed, the restriction of gypsum bed thicknesses and frequencies as well as, of the approximate nill karstification.

    Opis:
    Over the last two decades, geodetic surveying has seen significant advancements with terrestrial and unmanned aerial vehicle (UAV) laser scanning, alongside automatic observations being increasingly utilised throughout the construction process. In the context of dam structures, periodic geodetic displacement measurements are a compulsory component of control measurements and safety assessments. In Poland, however, control measurements have largely remained rooted in traditional techniques such as classic linear and angular measurements and precise levelling. These methods are typically carried out within distinct control networks, i.e. without dual-function observation points and targets. Furthermore, network points (pillars, targets) have often not been renewed since their installation several decades ago, and glass discs, used for crown measurements in the baseline method, frequently face damage. Changes in property ownership and modifications in environmental regulations are compounded by these issues, which often impede the proper upkeep of the sight line. The article proposes the adaptation and reconstruction of control networks to incorporate automatic observation techniques, including linear and angular measurements. This approach includes activities aimed at reconstructing and supplementing damaged network structures, modernising the geodetic process of determining structure displacements, and enhancing the accuracy, credibility, and reliability of geodetic displacement measurement results. The article presents the findings of an inventory assessment conducted on the existing control network infrastructure, focusing on the analysis of displacements for structures with diverse constructions and functions - a concrete dam (class I) and a water damming weir with a water intake. Furthermore, it presents practical conclusions regarding the efficient organisation of geodetic control measurements.

    Opis:
    Economic and political stability in Southeast Asia has led to a surge in Mekong dam development and construction in the 2010s. But, not only has the logistics of dam construction changed dramatically in the 35 years since Mekong hydroelectric development began; the public discourse surrounding hydroelectric development in the region has also expanded and diversified. The Mekong, while still seen by some throughout the region as a source of untapped economic opportunity, is also a source of growing concern for states who are losing control of the dams’ ecological impact. Both of these visions of the river are framed in the public imagination of various states by their respective media's chosen depiction of the issue of dam development. Through an examination of the discourse surrounding Mekong hydro development in the four Mekong River Commission (MRC) states, this paper explores the divergent interests of states currently engaged in a complex water diplomacy. Themes drawn from the English-language press coverage in Laos, Thailand, Cambodia, and Vietnam are compared to determine how the unique geographic and economic positioning of each state shapes their media's depiction of Mekong dam development. Shared concerns about environmental damage, MRC weakness, and economic futures are also explored.
    Ekonomiczna i polityczna stabilizacja w południowo-wschodniej Azji doprowadziła po 2010 r. do podjęcia decyzji o budowie zapór na rzece Mekong. Od czasu, gdy 35 lat temu rozpoczął się rozwój energetyki wodnej na rzece Mekong wiele się zmieniło i to nie tylko od strony logistycznej, także dyskusja publiczna odnosząca się do przyszłości hydroenergetyki w regionie uległa rozszerzeniu. Rzeka nadal postrzegana jest przez wielu jako potencjalne źródło ekonomicznego wzrostu, zarazem jest przedmiotem rosnących obaw dla krajów, które wydają się nie być w stanie utrzymać pod kontrolą ekologicznych konsekwencji budowy zapór. Oba podejścia trafiają do obiegu publicznego w poszczególnych krajach dzięki doniesieniom medialnym. W niniejszym artykule dokonano przeglądu dyskursu wokół rozwoju hydroenergetyki na rzece Mekong w czterech krajach należących do Komisji ds. rzeki Mekong (Mekong River Commission. MRC), ukazano rozbieżności w preferencjach poszczególnych krajów, zaangażowanych w skomplikowaną dyplomacje wodną. Porównano treści publikowane w anglojęzycznej w Laosie, w Tajlandii, Kambodży i Wietnamie, w celu ustalenia, w jaki sposób unikalne położenie geograficzne i gospodarcze każdego państwa kształtuje obraz ich mediów w kontekście budowy kolejnych zapór na rzece Mekong. Omówiono również wspólne obawy dotyczące szkód wyrządzonych środowisku naturalnemu, słabości komisji MRC i konsekwencji tego stanu dla przyszłości ekonomicznej regionu.

    Opis:
    Increased seepage processes, including leaks and resulting internal erosion processes, are among the main threats to the safety of dams and levees and to the safety of deep excavations and nearby buildings. These processes can significantly affect the cost of exploitation of damming structures and the costs of construction of underground parts of buildings. One of the basic methods currently used indetecting and analysing these processes is the thermal monitoring method. This method has been used successfully for several decades, particularly in Western Europe and has evolved substantially in the last decade. Currently it is being implemented in pilot applications in Poland. The paper describes the risks and consequences of leaks and internal erosion processes for a damming structure and deep excavation. The authors present the basic issues concerning the method of thermal monitoring based on their professional experience in numerous applications of thermal monitoring methods in both hydraulic engineering and geotechnics. The paper shows examples of thermal monitoring application in the analysis of dams and deep excavations.
