    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 design of small water reservoirs in Slovakia and neighbouring countries has common origins in the middle of the last century. Most of them were an alternative source of water for irrigation of field crops. Nowadays, we have to face new problems, such as the problems with the design of hydrological data and real current discharges, the problems with original and new design of the flood wave for the solution of the safety overflow. All of Q100 flows recorded nowadays are much higher than those which had been designed and built. The safety overflows no longer answer the purpose of the contemporary flows. The problems with the Framework Directive are also important – small water reservoirs are not resolved in the Directive as the water bodies of stagnant water because they have an area of less than 0.5 km2. The same problem is also with the preservation of continuity of the flow and the fact that they should let the fish pass. Unfortunately, the state, administrators of small dams, operators and nature conservationists have different points of view on the above-mentioned problems. The article elaborates these problems and suggests possible solutions to the problems.

    Opis:
    Międzyodrze is an area in Lower Odra Valley, from the fork of the riverbed to Szczecin, with the islands between the Odra River and Lake Dąbie. In the past, it has served primarily as a waterway route and now serves a variety of economic and nature-related functions. This paper presents the historical and present role of Międzyodrze, taking into account the specific natural values of the Lower Odra Valley, hydrography, hydrology and soil conditions. In the area of Międzyodrze, there are basically three types of organic matter and the nature’s point of view, the area is rich in flora and fauna. The current stimulation to activity of Międzyodrze is to take account of the needs of the natural environment, tourism and recreation, while improving the hydrological and retention potential of the area. Exceptional natural values, complicated hydraulic system of canals, the complexity of hydrological phenomena and the specificity of soils make the selection of activities aimed at achieving the objectives of area revitalization requires comprehensive environmental and hydrological analyses as well as economic analyses. The paper outlined the range of difficulties encountered by this assessment.
    Międzyodrze to obszar w Dolinie Dolnej Odry, od rozwidlenia koryta do Szczecina, wraz z wyspami pomiędzy Odrą i jeziorem Dąbie. W przeszłości służyło głównie jako szlak transportu wodnego, a obecnie pełni różnorodne funkcje gospodarcze i przyrodnicze. W pracy scharakteryzowano historyczną oraz obecną rolę Międzyodrza z uwzględnieniem specyficznych walorów przyrodniczych Doliny Dolnej Odry, hydrografii, hydrologii i warunków glebowych. Na obszarze Międzyodrza występują zasadniczo trzy rodzaje utworów organicznych (mada właściwa na torfie, gleba torfowa saprowa typowa, gleba torfowa limnowo-saprowa), a z przyrodniczego punktu widzenia obszar charakteryzuje się bogactwem flory i fauny. Prowadzona obecnie aktywizacja Międzyodrza ma uwzględniać potrzeby środowiska przyrodniczego, turystki i rekreacji, a jednocześnie poprawić potencjał hydrologiczny i retencyjny obszaru. Wyjątkowe walory przyrodnicze, skomplikowany system hydrauliczny kanałów, złożoność przebiegu zjawisk hydrologicznych oraz specyfika gleb sprawiają, że wybór działań zmierzających do osiągnięcia celów rewitalizacji obszaru wymaga wszechstronnych analiz przyrodniczo-hydrologicznych, a także analiz ekonomicznych. W pracy zarysowano zakres trudności w przeprowadzeniu takich analiz.

    Opis:
    Torfowiska, szczególnie torfowiska wysokie, uznawane są za niezwykle cenne przyrodniczo obszary. Dlatego przemysłowa eksploatacja torfu, w praktyce głównie z torfowisk wysokich, poddawana jest silnej krytyce. Za szczególnie szkodliwe uznaje się odwadnianie wyrobisk, które ma jakoby prowadzić do bardzo niekorzystnych zmian stosunków wodnych w okolicy. Pogląd ten w świetle praktyki i wyników badań nie znajduje potwierdzenia. Eksploatowane torfowiska wysokie posiadają autonomiczne warunki hydrogeologiczne i hydrologiczne. Stan ten nie zmienia się istotnie w wyniku eksploatacji, co radykalnie ogranicza jej oddziaływanie na otoczenie. W artykule przedstawione są warunki wodne w różnych torfowiskach wysokich, w zależności od położenia w typowych sytuacjach geologicznych, oraz zmiany warunków wodnych wywołane eksploatacją torfu.
    Bogs, especially raised bogs are recognized as environments of extreme natural value. This is why peat industrial exploitation, in fact mainly from the areas of raised bogs, comes across strong criticism. Drainage of peat excavation sites is considered to affect the adjacent water regime negatively. Such an outlook, in the light of current praxis and results of researches, is not confirmed. Raised bogs possess autonomic hydrogeological and hydrological systems. They are not likely to change during the exploitation which limits the interaction radically. Water regimes within raised bogs are described in this article. Their local geological conditions and water regime variation due to exploitation has been investigated.

    Opis:
    This work deals with the processes of deglaciation occurring in the region of SSSI No 8 (Site of Special Scientific Interests No 8) located on the western coast of the in the vicinity of Polish H. Arctowski Station over the period 1979-1999. The location of the SSSI is shown in Fig. 1. The basis of this work is comparison between the category of the surface of the area on the charts from 1979 (Furmańczyk & Marsz, 1980) and on the chart from 1986 (Battke, 1990) and the ground measurements carried out in that area in 1999 (Battke & Pudełko, unpubl.). The categories of area were computed on maps with the help of a planimeter: - glaciated areas, - non-glaciated areas (formed by mineral grounds), - sea areas. The accuracy of total measurements of the area is not lower than about 0.2 km2. The results of cartometric measurements are given in Table 1. Over the period 1979-1999 the area of SSSI decreased by 0.86 km2 as an effect of regression of icy cliffs both of Ecology and Baranowski Glaciers and due to accompanied abrasion process. At the same time the glaciated area within the borders of SSSI decreased by 6.93 km2 and the ice free area increased by 6.08 km2. In this way the mean rate of deglaciation of the 21-year period reaches about 0.33 km2 per year. Over the 21-year period the ice free area within the borders of SSSI incresed three times (from 2.98 km2 to 9.06 km2) which results in various consequences on the physico-geographical and biological prosesses in the region of the Admiralty Bay. In the period 1978-1986 the processes of deglaciation observed north of SSSI in the region of Ecology Glacier were faster than in other regions. Over the period 1986-1999 much faster decrease in the glaciated area was noted in the south of the area, in the region of Baranowski Glacier and Tower Glacier spatial changes are presented in Fig. 2. The analysis of reasons having influence on so advance processes of deglaciation indicated to two factors i.e. climatic and hydrological that are both responsible for the process. Over the period 1978-1998 in region of the Admiralty Bay the increase in air temperature during the Antarctic summer (period December - February; trend +0.022°C/year, statistically not significant) was noted. At the same time the period in which ablation was observed (warmer November and March) was longer. The annual sums of precipitation in the same period indicate to the presence of statistically significant negative trend (-5.7 mm/year, p < 0.005). This resulted in the change in the glacier mass balance at the level 2 m. above sea level: from -115 g/cm2/year in 1979 to -146 g/cm2/year in 1998 (Fig. 3). The evaluated trend of change in mass balance is -1.56 g/cm2/year and is not statistically significant. The period during which sea ice cover is not observed also lasts longer and the ice conditions there became visibly milder. This enables the thermal abrasion to last longer and causes more active regression of ice cliffs. On the shore of the Bransfield Strait, between the Admiralty Bay and the Maxwell Bay entrance a deep cove was formed in the ice coast over the period 1985-1988. This resulted in the increase in inclination of the southern slopes of ice forming the Warszawa Ice cap and forced the volume of ice flowing towards the Bransfield Strait to increase. In this way the volume of ice flowing down the Warszawa Ice Cap eastward, to SSSI No. 8 area, decreased. The explanation of reasons responsible for the ice conditions becoming milder can be found in large scale changes in sea surface temperature of the Southern Ocean of the sea area located West of the Antarctic Peninsula (a strong positive trend SST is marked in the period from October to January; in December +0.058°C/year) and in changes in atmospheric circulation. Both these factors, i.e. the increase in the negative values of the ice masses balance and the decrease in the volume of ice flowing down on the SSSI No. 8 area act in the same direction, causing that the deglaciation process in that region occurs in an exceptionally intensive way. Due to such great intensity of the deglaciation processes occurring on the surface of SSSI in that area, this area can be regarded as a unique object of ecological and environmental research.
