Opis:
Każdy obiekt mostowy charakteryzuje się oryginalnymi rozwiązaniami, możliwościami technologicznymi zastosowanymi w trakcie jego budowy oraz unikalnym charakterem (modą) dostosowanym do czasu swojego powstania. Obiekty zamieszczone w pracy posiadają cechy szczególne dla danego regionu, które są warte przedstawienia w kontekście rozwoju konstrukcji mostowych, myśli inżynierskiej, przeobrażeń społecznych oraz wydarzeń historycznych. We wszystkich zamieszczonych obiektach głównym materiałem konstrukcyjnym jest stal. Każdy z nich był lub jest mostem kolejowym (kolejowo autostradowym). Omówione zostały przykłady mostów powstałych w różnych epokach. Pozwala to w szerszym ujęciu zaobserwować pewien trend, myśl przewodnią ewolucji inżynierii mostowej, która na przestrzeni czasu stale wyznacza nowe perspektywy oraz możliwości pokonywania problemów komunikacyjnych.
Every example of bridge both the aesthetic appearance and technological solutions are unique. Differences are a result of a various historical events, neighbour impact and evolving capabilities of bridge building. Based on the unique features of bridge examples taken into consideration one reveals evolution technology of bridge building in time. The aim is to present some examples of steel bridges which have been considered successful. Bridges are still in use. Each of them was created in different period of time. It shows the altered bridge building idea, fluctuation of trend. The successful design was able to have been improved during time when increasing road traffic forced engineers to adapt bridges into new conditions. Bridge builders found a positive solution to every appeared problem. It help to preserve bridges from being rebuild and clearly showed that bridge building is the finest domain of civil engineering.

Opis:
A study has been conducted on the use of alternative energy sources for propulsion of a vessel in inland waterway transport. It is clear that at this stage it is most appropriate to use a vessel designed for short-haul trips between two banks of a ferryboat for passengers and luggage or for recreation and entertainment. On this basis, research has been conducted on a newly designed and built vessel to carry up to 12 people. The drive is fully powered by 180-Ah batteries at 48 V. The batteries are charged by the sun through 5-kW solar panels. The results show that the vessel powered by two 5-kW electric motors can sail autonomously for about 1.5 hours, to travel about 13 km, at an average speed of 7.9 km/h with an average energy consumption of 71.3 kWh/100km when sailing on a linearly reversible route including sailing downstream and upstream on the Danube River.

Opis:
An issue of mean residence time (MRT) evaluation, i.e. the period of time from rainfall until drainage of groundwater by rivers (Danube River Basin, Vistula River Basin and Narew River Basin), is discussed Asimple method of evaluating the groundwater MRT for the Danube River Basin based on tritium data is introduced. It has been confirmed that the historical tritium level in the rivers, being higher than in precipitation, has its end and is reversed, opening a new pathway in understanding the surface-groundwater interaction and specifically in evaluating MRT of groundwater. The authors have defined a separate notification for mean residence time of the whole water in the basin (τ) and mean residence time for groundwater in the basin (τwp). Based on the tritium study the obtained τ values are 6.5 and 5.7 years for the Vistula River Basin (VRB) and the Narew River Basin (NRB), respectively. In turn, the obtained τwp values are 8.0 and 6.0 years, respectively. NRB is a lowland plain and a morphologically, geologically and hydrogeologically uniform basin. The obtained τ wp of groundwater is thus representative for the whole basin. Instead inmorphologically non uniform VRB basin groundwater τwp is a generalized value,i.e.averaged over contributed parts of the basin.

Danube River
Opis:
The Danube River Basin is shared by 19 countries, which makes it the world’s most international river basin. More than 81 million people of different cultures and languages live in the Danube Basin and they all are interconnected through the widely ramified water system of the Danube. The cultural variety is not only a valuable attribute of this region, but it also causes barriers related to the transport of goods and passengers on the Danube waterway and its navigable tributaries. The abundant existence of administrative barriers in Europe limits the economic and environmental potentials of inland waterway transport (IWT) as a sustainable mode of transport. These administrative barriers consist for example in reporting requirements that vary considerably among fairway authorities and Danube countries. Most often, reports or data provided cannot be re-used across countries or is not available requiring additional input or additional reporting activities by the barge operator. The objective of this paper is to identify administrative barriers for IWT on the Danube and develop solutions for improved procedures and processes. Data is collected from a dense network of stakeholders operating along the Danube. National focus groups were held to analyse the procedures and administrative processes in inland waterway transport and identify barriers. Further, an online-survey has been set up to collect data. Potential solutions are developed in a cooperative way together with involved operators and authorities. The philosophy of lean administration suggests that non-value added activities (“waste”) must be identified in a first step to make processes more efficient. A diverse number of non-value added administrative barriers were therefore identified in the countries along the Danube. Afterwards, Port Community Systems are introduced as a possible solution to overcome administrative barriers.

Opis:
The Danube and its tributaries have been crossing mountains and plains in their almost unchanged riverbeds for thousands of years, regardless of national and administrative boundaries. Nevertheless, even decades ago, several countries provided access to only limited data and information concerning the water level and flood protection status of their rivers. In recent years, information was exchanged mainly on the basis of bilateral agreements and on successful activities of basin-wide organizations, but for others, information could only be obtained by browsing the Internet, which is sometimes rather complicated and definitely time-consuming. The EU Strategy for the Danube Region Environmental Risks Priority Area initiated a project aimed at developing the Danube Hydrological Information System, which was supported by the International Commission for the Protection of the Danube River. A comprehensive overview of the complex national flood and ice forecasting systems, identification of the shortcomings of the existing forecasting practices as well as an improvement of the exchange and availability of hydrological and meteorological data between the involved countries constituted crucial fields of interests for the project. Hence the main aim of the article is to present and discuss key data and functionalities of the system. The key findings show that all authorized meteorological and hydrological data of the Danube River are stored in a central database and made available online to all licensed hydrological and flood protection institutions for further processing in virtually real time. At this moment 12 countries of the Danube have joined forces to work out the proposals that are essential for the future, for safer Danube.
Dunaj i jego dopływy przecinają góry i równiny w swoich prawie niezmienionych korytach od tysięcy lat, nie zważając na granice państwowe i administracyjne. Mimo to jeszcze kilkadziesiąt lat temu kilka krajów udostępniało jedynie ograniczone dane i informacje na temat poziomu wód i stanu ochrony przeciwpowodziowej swoich rzek. W ostatnich latach informacje przekazywane były głównie na podstawie umów dwustronnych i pomyślnie realizowanych działań organizacji działających w całym dorzeczu, ale dla innych informacje można było uzyskać jedynie poprzez przeglądanie Internetu, czasem w dość skomplikowany sposób i z pewnością wymagający czasu. Strategia UE dla Obszaru Priorytetowego Ryzyko Środowiskowe Regionu Dunaju zainicjowała projekt mający na celu rozwój Systemu Informacji Hydrologicznej Dunaju, który był wspierany przez Międzynarodową Komisję Ochrony Rzeki Dunaj. Kompleksowy przegląd złożonych krajowych systemów prognozowania powodzi i oblodzenia, identyfikacja braków w istniejących praktykach prognozowania, jak również poprawa wymiany i dostępności danych hydrologicznych i meteorologicznych pomiędzy krajami uczestniczącymi w projekcie stanowiły kluczowe obszary zainteresowania projektu. Dlatego też głównym celem artykułu jest przedstawienie i omówienie kluczowych danych i funkcjonalności systemu. Z najważniejszych ustaleń wynika, że wszystkie autoryzowane dane meteorologiczne i hydrologiczne dotyczące rzeki Dunaj są przechowywane w centralnej bazie danych i udostępniane online wszystkim licencjonowanym instytucjom hydrologicznym i ochrony przeciwpowodziowej do dalszego przetwarzania w czasie praktycznie rzeczywistym. W tej chwili 12 krajów naddunajskich połączyło siły, aby wypracować propozycje, które są niezbędne dla przyszłości, dla bezpieczniejszego Dunaju.

Opis:
The article presents two floating architectural structures developed in response to the needs of local communities. The first one – a river barge “Louise-Catherine” – was adapted in 1929 according to the design of Le Corbusier, one of the most influential architects of the first half of the 20th century, for the purposes of Salvation Army shelter docked on the Seine in Paris and it continued its operation as such until 1994. The second one – Bertha von Suttner state junior high school – was developed in a shipyard to serve as a school, which purpose it has been fulfilling since 1994 while moored on the Danube River in Vienna. The author’s intention was to describe both structures while highlighting common features as well as differences, and to analyse them in view of certain selected aspects. The background for the projects’ development was described account taken of different reasons and circumstances. Issues under analysis include decision making processes in terms of architectural programme, functions and spatial developments. The analysis also includes technical aspects such as structural developments, material and infrastructure – in terms of the floating Viennese school – account taken on safety of using a barge as a school establishment. A separate part of the article is dedicated to the issue of social reception, and in case of the former Salvation Army shelter – actions aimed at the protection of a historic structure.

Opis:
Urban environment management (UEM) and environmental social science (ESS) are two interconnected approaches that show significant potential for creating more sustainable and liveable cities. Their research has, however, been mainly disjointed, which may be because planning and policy have placed more emphasis on UEM than ESS at the same time. This research examined ESS in terms of the quality of life (QOL) criteria and sense of place (SOP) of citizens living by the river with the UEM intervention in the form of policies and programmes. The effects of fieldwork in the form of specialised and spatial interviews are presented in this research, which is usually ignored in the literature review of this type of analysis. The study aims to fill the current gap in this field in three European capitals by providing a reflective methodological account of fieldwork and the ‘elite interviewing’ approach. This paper produces a distinct form of the localisation of the research and sampling techniques and is as new, interactive and developing as possible. The results of the present study are underpinned by the conceptual model of research, which supports the main aim of this analysis and tries to examine the components of research in a new perspective. The findings high- lighted that maintaining and strengthening ESS for citizens living next to rivers require innovative UEM, which uses urban creativity in the field of goals, urban settlements, strategies and management solutions to provide the base for increasing the liveability of the city and improving the quality of urban life.

Opis:
The reign of the Doukas dynasty in 1059–1078 was a time when new threats to the Byzantine Empire emerge in Europe and Asia. One of them was the increased activity of Turkmen who were penetrating the lands belonging to the Byzantines. A manifestation of these threats was visible during the rule of Constantine X Doukas (1059–1067) in 1064. We have there an invasion of the tribe of Uzes, who crossed the Danube. They ventured so far, as the vicinity of Thessalonica and the province of Hellas, plundering everything in their path. Their actions surprised the defense of the Byzantines. This attack on the empire was related to their crossing of the Danube, about which Michael Attaliates and Skylitzes Continuatus provides us with interesting information. The main aim of this paper therefore will be related to issues linked to the types of vessels used by Uzes to cross this river, as well as an attempt to assess their boatbuilding skills.

Opis:
Development of the river sea transport is directly related to the characteristics of waterway network which enables navigation between river basins and seas. Inland waterways in Serbia belong to the Danube navigational system. There are two navigational directions: Danube East and Danube West. River-sea transport can be directly established in these directions between the Serbian international ports on the Danube (Apatin, Novi Sad, Belgrade, Pan?evo, Smederevo and Prahovo). Development of the Pan-European Corridor VII and the River Danube-Black Sea and Danube-Rhine-Main region would allow not only in Serbia but also in neighbouring states and all over Europe connection with the sea. In this paper the technical and exploitation characteristics of the river Danube will be analysed in terms of the navigation of various river and sea vessels with different exploitation characteristics.
