Opis:: Rainfall in the Lake Tana basin is highly seasonal and the base flow contribution is also low resulting in the need for reservoirs to meet the agricultural demand during the dry season. Water demand competition is increasing because of intense agricultural production. The objective of this study is to develop water balance models. The Mike Basin model has been selected for water allocation modelling and identifying potential changes needed to the existing water allocation scheme to reduce the stress due to increased water demand. The study considers baseline and future development scenarios. The construction of new dams results in two competing effects with respect to evaporation loss. The first effect is increased evaporation from new reservoirs, while the other is reduced evaporation from the Lake Tana as a result of a decreased surface area of the lake and reduced inflow of water to the lake. Once a dam is built, there will be an additional free water surface area and more evaporation loss. In dry months from January to May, the irrigation water demand deficit is up to 16 Mm3. It is caused by reservoirs built in the basin, which reduce the inflow to the Lake Tana. The inflow varies between wet and dry months, and there is more water flow in wet months (July, August and September) and reduced flow in dry months because of the regulatory effects produced by the reservoirs.

Abrămuţ Basin
Opis:: Detailed lithostratigraphic data from a borehole in the Abrămuţ Basin, located in the northwestern part of Romania, has revealed the presence of turbiditic deposits containing several layers with tuff/tuffaceous materials in the lower Badenian. The age of these deposits is determined by the presence of the foraminifera Praeorbulina glomerosa and Orbulina suturalis. Detailed quantitative and qualitative X-ray diffraction data (XRD) on 10 different tuff layers situated at depths between 2450 and 2640 m show a mineralogical association comprising analcime, quartz, volcanic glass, smectite, mica, calcite, K-feldspar, glass and minor quantity of chlorite and albite. The presence of analcime suggests that the albite isograd for the interval studied has been never reached and the maximum temperatures have been lower than c. 125degrees C since the early Badenian.

Opis:: Elemental and mineral composition of Gold Basin and El Hammami meteorites discovered in 1995 and 1997 have been studied by analytical electron microscopy and optical microscopy. It was established that the main meteorite minerals: olivines, pyroxenes, kamacite and taenite as well as troilite identified in the samples represent extraterrestrial minerals typical of the ordinary chondrites. Feldspars represented by plagioclase, orthoclase, magnetite, calcite, chromite and silica have been also present in the studied samples. Chemical and mineral composition, iron content, petrologic types of chondrules, their abundance and sizes, the presence of troilite veins and abundance of nonoxidised iron phases confirm H class of El Hammami chondrite, i.e.. olvine-bronzite class, and L class of Gold Basin, i.e. olivine-hyperstene class.
Badano skład chemiczny i mineralny meteorytów Gold Basin i El Hammami. Zanalizowano chondry i ciasto skalne. Obecność chondr oliwinowych, chondr piroksenowych, żył troilitowych oraz faz żelazo-niklowych: kamacytu i troilitu świadczą o pozaziemskim pochodzeniu badanych skał. Oprócz minerałów najbardziej rozpowszechnionych w meteorytach takich jak: oliwin, piroksen, kamacyt, taenit i troilit wykryto także plagiklazy, magnetyt, kalcyt, chromit, ortoklaz i krzemionkę. Zgodnie z uprzednią klasyfikacją Gold Basin jest chondrytem klasy L o niskiej zawartości żelaza, a El Hammami chondrytem typu H zawierającym dużo żelaza.

Opis:: Water-table levels in the Kamienna River drainage basin, SE Poland, are presently measured at 14 observation points within the groundwater observation-research network of the Polish Geological Institute – National Research Institute, included in the monitoring programme during the period 1979–2007. They exhibit multi-year changes in groundwater storage near the observation points. The best documented cycle is that for the period 1982–2002, observed in the wells monitoring water in fractured-karstic formations, where the amplitude of the water-table level was 45 m at that time. The retention balance in the cycle was negative. At the beginning of the cycle, the water table in the fractured-karstic aquifers was 1.40 to 1.94 m higher than at the end. Further observations of the multi-year changes in retention will be the basis for possible corrections to calculations of groundwater resources in this drainage basin, as well as for model predictions of resources, performed for water management in connection with potential climate change.

Opis:: The Shaximiao Formation (Sichuan Basin, China), and the corresponding Chuanjie Formation of the neighboring Yunnan Basin (Sichuan-Yunnan Basin), representing continental Mesozoic strata, are distinguished from other Chinese Mesozoic units because of the large area over which they are distributed, their lithological characteristics and their abundant vertebrate fossils. This paper analyses and summarizes the dinosaur fossils from the Shaximiao Formation and compares them to other vertebrate groups of the same or similar ages, both in China and abroad. For the first time, this paper presents the viewpoint that the upper member of the Shaximiao Formation is of Middle Jurassic age (Bathonian–Callovian). Furthermore, we claim that the entire Shaximiao Formation is of Bajocian–Callovian age (middle-late part of Middle Jurassic). This conclusion is supported by the age inferred from invertebrate fossils and radiometric dating (165–178 Ma). The composition, evolution and geological age of the vertebrate fauna (particularly dinosaur fossils), as well as their comparison to the dinosaur fauna from the other parts of the Sichuan-Yunnan Basin (Chuanjie Fm.) is discussed. Middle Jurassic dinosaur assemblages from China show marked differences compared with other dinosaur assemblages in the world, and this is explained by geographical isolation.

Opis:: The Late Cretaceous to Oligocene strata of the Dukla Nappe, which is a part of the accretionary wedge formed in front of the Carpathian orogen, record a history of the basin development from remnant to foreland basin stages. The lower part of the succession indicates the first stage of basin evolution characterized by turbidite systems fed from the E (NE) to W (SW). The system encompasses deposits of the Łupków and Cisna formations deposited in a channel-lobe transition (Łupków Fm.) and in sandstone-rich channelized lobes (Cisna Fm.) The transitional phase is represented by deposits of the Submenilite Formation derived from two different sources (SE and N) and deposited in a submarine slope/ramp environment. The third stage of basin evolution is marked by the advancing front of the Carpathian orogen resulting in peripheral foreland basin development. Increased tectonic activity led to a switch in sediment source from the SE to the NW, more complex topography of the basin and a change in sediment distribution. The initial phase of this stage is characterized by low-density turbidites and suspension fall-out sediments of the Menilite Fm. Discrete tectonic pulses are recorded by the thick Cergowa sandstones, mostly deposited by hybrid flows and high-density turbidity currents. A decrease in tectonic activity is suggested by heterolithic deposits of the Krosno Fm. capping the sedimentary succession.

Opis:: The Vistula is the largest river in Poland, which flows from the south to the north. Its mouth is on the Baltic Sea. As for hydrography the Vistula is divided into three parts: Upper – from its sources to the mouth of the River San, Middle – up to the tributary Narew River, and the Lower – up to its mouth on the sea. This article covers the Vistula and its basin management plans starting from the interwar period up to the present day. The location of the Vistula and its basin as well as land cover are described. The division of Poland into river basin districts and water regions accompanied by a description of administrative division of the country are described. Climatic conditions of Poland including precipitation and air temperatures are presented. Basic hydrological data of the Vistula and its basin is given. Parts of the Vistula basin, which are included in the Program of Natura 2000 are mentioned. Brief information concerning existing, more important hydraulic and hydroenergy structures in the main Vistula channel as well as on its tributaries are described.
Wisła jest największą polską rzeką, która płynie z południa na północ, a jej ujście znajduje się w Morzu Bałtyckim. Pod względem hydrograficznym Wisła dzieli się na trzy części: górną – od źródeł do ujścia Sanu, środkową – do dopływu Narwi i dolną - największą polską rzeką, która płynie z południa na północ, a jej ujście znajduje się w Morzu Bałtyckim. W artykule przedstawiono plany zagospodarowania Wisły i jej dorzecza, poczynając od okresu międzywojennego zą do chwili obecznej. Omówiono także położenie Wisły i jej dorzecza oraz pokrycie terenu z podziałem na sześć typów. Zaprezentowano podział Polski na obszary dorzecza i regiony wodne, jak również położenie dorzecza Wisły na tle podziału administracyjnego kraju. Przedstawiono warunki klimatyczne Polski, obejmujące opady atmosferyczne i temperatury powietrza. Podano również podstawowe dane hydrologiczne Wisły i jej dorzecza. Przedstawiono obszary dorzecza Wisły objęte Progamem Natura 2000. Podano krótkie informacje na temat istniejących ważniejszych budowli hydrotechnicznych i hydroenergetycznych w zasadniczym korycie Wisły, jak również na dopływach Wisły.

coal bed methane (CBM)
Opis:: Coal bed methane (CBM) may become an important source of energy in Upper Silesian Coal Basin. Coal bed methane in Poland occurs within three coal basins of which the best recognized and most promising is the Upper Silesian Coal Basin. Approximately 80.1% of proved balance of coal deposits resources in Poland occurs in the Upper Silesian Coal Basin, where 50 fields are operated by 28 mines. Thus, since early 90s of the 20th century the USCB is attractive for foreign companies which perform evaluation of coal bed methane obtaining possibility as main fossil. However, all previous attempts to commercial production of CBM did not bring expected results, but they constitute extensive information database for current and future research towards CBM exploitation. Prognostic resources of coal bed methane in USCB are estimated to 107 bln m3. Recoverable balance resources are estimated to 87.6 bln m3. Much smaller perspectives are related to the poorly identified regions of Lublin Coal Basin and Lower Silesian Coal Basin. It is estimated that balance resources of hard coal in LCB, represents approximately 19.2% of Polish hard coal balance resources.
