For this purpose experiments based on replicate sampling were undertaken on Polish lowland rivers. Analysis based on the series of experiments carried out as a part of this Workpackage, several surveys were combined with the WP7 (Core stream types) and a few comparisons with the STAR hydromorphological database were included. Concerning macrophyte methods, much attention was paid to the main STAR macrophyte method - Mean Trophyic Rank (MTR). Although, several analyses of variability of other methods were conducted. Concerning hydromorphological assessment, studies were focused on the main STAR hydromorphological method – River Habitat Survey (RHS). The workpackage provided an error estimations. Also the vulnerability of the tested methods were analysed and guidance for quality assurance was delivered. It supplements STAR error module in error estimations of MTR and RHS. The computer program module based on the developed set of criteria was prepared for quality support in hydromorphological assessment. 7 8 2 GENERAL DESCRIPTION Analyses based on the series of experiments were carried out from Spring 2003 to Summer 2004. Several surveys, which had been undertaken in 2003, were combined with the WP7 (Core stream types). Also several comparisons with the STAR hydromorphological database were included. 2.1 Staff The Workpackage was mainly completed by nine members of the staff of the Department of Ecology and Environmental Protection of August Cieszkowski Agricultural University in Poznan. Some support was gained by scientists from the Department of Agrometeorology and from the Department of Land Improvement, Environmental Development and Geodesy.

Pomeranian Bay as an ecotone is a transition zone between two different biocenoses, which is characterized by an increase in biodiversity and species density. Therefore, Pomeranian Bay is a destination of finding and reproductive migrations of fish from the rivers entered the area. The aim of the study was to compare parasitic fauna of two predatory fish species from the Pomeranian Bay, collected from the same fishing grounds at the same period. A total of 126 fish studied (53 perches and 73 zanders) were collected in the summer 2013. Parasitological examinations included: skin, fins, gills, vitreous humour and lens of the eye, mouth cavity, body cavity and internal organs. Apart from the prevalence and intensity of infection (mean, range) the parasite communities of both fish species were compared. European perch and zander were infected with parasites from five different taxonomic units. The most numerous parasites were Diplostomum spp. in European perch and Bucephalus polymorphus in zander. The prevalence of infection of European perch ranged from 5.7% ( Diphyllobothrium latum ) to 22.3% ( Diplostomum spp.) and for zander from 1.4% ( Ancyrocephalus paradoxus , Hysterothylacium aduncum ) to 12.3% ( Bucephalus polymorphus ).

  • Floods in Poland from 1946 to 2001 — Origin, Territorial Extent and Frequency
    Polish Geological Institute Special Papers, 15 (2004): 69–76 Proceedings of the Conference “Risks caused by the geodynamic phenomena in Europe” FLOODS IN POLAND FROM 1946 TO 2001 — ORIGIN, TERRITORIAL EXTENT AND FREQUENCY Andrzej DOBROWOLSKI1, Halina CZARNECKA1, Janusz OSTROWSKI1, Monika ZANIEWSKA1 Abstract. Based on the data concerning floods on the territory of Poland during the period 1946–2001, the reasons generating floods, the number of regional floods in the rivers catchment systems, and sites of local floods occurrence, were defined. Both types of floods: caused by riverbank overflows, and land flooding by rain or snow-melt water, were considered. In the most cases, the floods were caused by rainfall. They were connected with changes in the rainfall structure within Po- land. In each season of the year floods of various origin were observed. When the flood initiating factors appeared simulta- neously, the flood grew into a catastrophic size. In present analysis, for the first time in Poland, a large group of local floods has been distinguished. A special attention has been paid to floods caused by sudden flooding of the land (flash flood), including floods in the urban areas — more and more frequent during the recent years. The results of the analyses have provided important data for the assessment of the flood hazard in Poland, and for the creation of a complex flood control strategy for the whole country and/or for selected regions. Key words: flood, classification of floods, floods territorial extent, frequency of floods occurrence, torrential and rapid rain- fall, threat of life, material losses. Abstrakt.

  • The Evaluation of Hydrodynamic Balance at the Wkra River Estuary
    Vol. 4 Issue 2 December 2016 The evaluation of hydrodynamic balance at the Wkra River estuary Piotr Siwicki, Janusz Urbański, Leszek Hejduk, Jacek Gładecki Warsaw University of Life Sciences (SGGW), Nowoursynowska 166, 02-787 Warsaw, Poland, e-mail: [email protected], [email protected], [email protected], [email protected] Abstract. The river bed stability analysis at the Wkra estuary reach is presented in this paper. When a flood appears, channel and river bed erosion can reach a significant size. During such a situation, flow and water velocity exceed critical values for particular bed sediment grain sizes. This causes the breakage of bed armouring, and then bed mass motion begins. For the estimation of the sandy Wkra River bed the criteria of average velocity and bed armouring were applied with the use of ARMOUR software. The two Wkra River cross-sections at km 1+000 and km 3+200 distance were ana- lysed. The calculation of the characteristics of bed sediment velocities was performed on the basis of, among other factors, probable river flow data, longitudinal slope, and grain size distribution of the bed. The results of the calcula- tions were compared with average velocities in the analysed cross-sections. The results indicate the there is a threat to the stability of the Wkra River bed, especially during long-lasting high water stages. The prognosis of river bed stability loss performed by use of ARMOUR software shows that the bed armour breakage will take place in both considered cross-sections at relatively low water stages (about 40 cm), and mass motion of bed sediments in cross-section P-2 will occur at a flow of slightly lower thanQ 50% ,and in cross-section P-1 at flows greater thenQ 0,3%.

  • Transformation of the Flow Regime of a Large Allochthonous River in Central Europe—An Example of the Vistula River in Poland
    water Article Transformation of the Flow Regime of a Large Allochthonous River in Central Europe—An Example of the Vistula River in Poland Dariusz Wrzesi ´nski and Leszek Sobkowiak * Department of Hydrology and Water Management, Institute of Physical Geography and Environmental Planning, Faculty of Geographical and Geological Sciences, Adam Mickiewicz University, Krygowskiego str. 10, 61-712 Pozna´n,Poland; [email protected] * Correspondence: [email protected] Received: 31 December 2019; Accepted: 10 February 2020; Published: 12 February 2020 Abstract: Identification of river flow regime and its possible changes caused by natural factors or human activity is one of major issues in modern hydrology. In such studies different approaches and different indicators can be used. The aim of this study is to determine changes in flow regime of the largest river in Poland—the Vistula, using new, more objectified coefficients and indices, based on data recorded in 22 gauges on the Vistula mainstream and 38 gauges on its tributaries in the multi-year period 1971–2010. The paper consists of three main parts: in the first part, in order to recognize changes in the flow regime characteristics along the Vistula, data from gauges located on the river mainstream were analyzed with the help of the theory of entropy. In the second part gauging stations on the Vistula mainstream and its tributaries were grouped; values of the newly introduced pentadic Pardé’s coefficient of flow (discharge) (PPC) were taken as the grouping criterion. In the third part of the study a novel method of determining river regime characteristics was applied: through the recognition of the temporal structure of hydrological phenomena and their changes in the annual cycle sequences of hydrological periods (characteristic phases of the hydrological cycle) on the Vistula River mainstream and its tributaries were identified and their occurrence in the yearly cycle was discussed.

  • Potamonyms of the Vistula River Basin As a Part of Cultural Heritage
    Potamonyms of the Vistula River Basin as a Part of Cultural Heritage Urszula BIJAK* There are many ways in which cultural heritage can be defined, depending on the branch of science that is dealing with this term. With no doubt, a language, including proper names, is a medium of the non-material cultural heritage. The aim of my article is to present a “hydronymic map” of the Vistula basin from the linguistic point of view. I will focus on: 1/the cultural heritage reflected by the river names, which are chronologically and genetically differentiated and represent several layers: archaic Pre- Slavic names, so-called “Old-European”, Polish, other Slavic (Czech, Slovak, Boyko, Lemko, Ukrainian, Belarusian) and non-Slavic (Baltic, German, Vlach, Latin); 2/ the image of the lingual reality constructed by the river names, the creation of names which is a result of action of a number of different motives, incentives, ways of thinking and experiencing the reality; 3/the changes of hydronyms, variability (so called polyonymy) characteristic for this onimic category coming from the lack of naming memory, collapse of naming tradition through the centuries. 1. Introduction There are many ways in which cultural heritage can be defined, depending on the branch of science that is dealing with this term. The conceptual and territorial range of the term can also differ (Lewandowska 2007). With no doubt, a language, including proper names, is a medium of the non-material cultural heritage. Hydronymy occupies a significant position within the realm of geographical names and from the beginning of the 20th century it played an important role as a research topic for linguists.

  • Basic Parameters of the Thermal Regime of Rivers in the Vistula River Catchment
    Vol. 14/2010 pp. 185-192 Oksiuta Monika University of Warsaw Faculty of Geography and Regional Studies Department of Hydrology e-mail: [email protected] BASIC PARAMETERS OF THE THERMAL REGIME OF RIVERS IN THE VISTULA RIVER CATCHMENT Abstract: Seasonal and multi-annual variability of river water temperature has been ana- lysed based on data from 24 gauge stations of the IMGW network. It has been character- ised by means of several values of the thermal regime parameters: mean annual, semi-annual (November-April, May-October) and amplitude. The variability of water temperature in the catchment and in the stream network has been estimated. Measurement data included seven stations at the Vistula river. On the background of natural variability, rivers or their segments have been distinguished where water temperature is impacted by anthropopressure. Key words: thermal regime, river water temperature, Vistula river catchment. INTRODUCTION River water temperature is an important characteristic of the environ- ment, but little is known about its variability. Studies conducted in small experimental catchments allowed to determine the dependence of water temperature on air temperature (Calow, Petts, 1994; Mohseni, Stefan, 1999), type of catchment utilisation (Young et al., 2005), substratum lithology (Young et al., 2005), and type of alimentation (Gutry-Korycka, 1967). The author did not compare their results to studies conducted on the scale of a catchment. The results of the first extensive studies of the thermal condi- tions of Polish rivers were presented many years ago by J. Gołek (1961). Later studies of temperature were mostly of practical character and con- sisted in the estimation of the impact of heated water from power plants to rivers (Jaworski, 1969; Taboryska, 1987).

  • EDWARD RYDZ-ŚMIGŁY a Political and Military Biography
    EDWARD RYDZ-ŚMIGŁY A Political and Military Biography Ryszard Mirowicz Translated and edited by Gregory P. Dziekonski The copyright over the translation has been granted to the translator by the copyright holder of the original Polish text, and I authorize the University of Washington Libraries to make the full text of the English translation available to readers worldwide. TRANSLATOR’S NOTE The original Polish version of this book was written in the 1980s under communist rule, and remained dormant in a censor’s office for over a year. The author was ordered to alter various references concerning the Teschen dispute in 1938 and the Soviet invasion of Poland in alliance with the Nazis in September, 1939. Although the author expressed satisfaction at the eventual compromise between mandated omissions and academic integrity just prior to publication, the translator has made an attempt to add a few footnotes to provide some balance to the narrative. Regarding the customary problems with geographical locations in multiple languages, most locations described in First World War battles on the eastern front in which the Legions were involved and the post-war military operations in the Ukraine, Byelorussia, and Lithuania are in Polish. Otherwise, respective languages for whichever countries in which the geographic locations happened to be situated at the time are used. English names were used for those which possess them, such as “Warsaw,” “Cracow,” “Kaunas,” etc. Numbered footnotes are mostly identical to those in the original text and are listed at the end of each respective section. Footnotes with an asterisk at the bottom of the page are citations which the translator has added.

  • The Ichthyofauna of the Regulated Section of the Nida River (The Upper Wkra) in the Commune of Nidzica
    POLISH JOURNAL OF NATURAL SCIENCES Abbrev.: Pol. J. Natur.

Abstract The purpose of this study has been to characterize the ichthyofauna of the Upper Wkra River during the initial stage of the implementation and execution of revitalization of the Nida River in the commune of Nidzica. The study covered a nearly 5-km-long section of river flowing across the commune of Nidzica. Four sites of control catches were localized between the administrative border to the town of Nidzica and a water-raising fixed weir (h=1.40 m) in the village called Borowy Młyn. In the fish assemblage, dominated by three- and ninespined stickleback, nine species in total were observed. By referring to the available research results, it can be concluded that no significant quantitative or qualitative changes occurred in the structure of the inchthyofauna from 2001 to 2008. One of the factors which limit the process of natural regeneration of the fish population is the fact that the analyzed section of the river is cut off from the remaining part of the Wkra River and its tributaries.
