W artykule przedstawiono wyniki analizy struktury i czasu trwania zjawisk lodowych na Warcie w latach 1991–2010. Przebieg zjawisk lodowych został opisany na tle zmian temperatury powietrza i wody oraz wskaźnika Oscylacji Północnoatlantyckiej (NAO). Określono formy zjawisk lodowych występujących na Warcie w poszczególnych cyklach jej zlodzenia. Zinterpretowano również zmienność temperatury wody w okresie zimowym i jej wpływ na liczbę dni ze zjawiskami lodowymi. W analizie zjawisk lodowych uwzględniono: charakter odcinka rzeki, na którym prowadzono obserwacje oraz stopień antropopresji, wyrażający się przekształceniem koryta rzecznego, wpływem urbanizacji w strefach większych ośrodków miejskich oraz oddziaływaniem zbiornika Jeziorsko. Na podstawie przeprowadzonych badań wyznaczono ogólną tendencję w zmienności zjawisk lodowych występujących na rzece, a także określono przyczyny zróżnicowania struktury zjawisk w ujęciu regionalnym. Stwierdzono związek pomiędzy przebiegiem i częstością zjawisk lodowych a warunkami termicznymi i fazami NAO.

The article presents the results of the analysis of the structure and duration of ice phenomena on the Warta River. The course of ice phenomena has been described against the background of air and water temperature, and North Atlantic oscillation (NAO) changes including. The forms of ice phenomena, exist on the Warta River in particular cycles of its icing, were determined. The variability of the water temperature in winter and its impact on the number of days with ice phenomena on the river has been taken into consideration. The analysis of ice phenomena has taken into account the nature of the section of the river on which observations were made, the scale of anthropopressure affecting the transformation of the riverbed, the impact of urbanization in the zones of larger urban centers and the influence of the Jeziorsko Reservoir. On the basis of the conducted research, a general tendency was determined for the variability of ice phenomena occurring on the river. Reasons for the differentiation of the structure of ice phenomena on a regional basis were determined. The results show in detail the connection between the course and frequency of ice phenomena and other hand thermal conditions and NAO phases.

Assessments of the infiltration recharge of groundwater are performed using various methods and on different scales. Infiltration is dependent of climatic factors, aspects of water circulation, as well as on quasi-stationary and variable environmental features of a specific area, which are frequently difficult to determine on the basis of direct measurements or observations. The objective of the present study was to identify factors conditioning recharge of shallow groundwater in selected catchment areas of the Poznań Upland using the WetSpass simulation water balance model with spatially distributed parameters. Our analysis has indicated favourable and unfavourable conditions for recharge of groundwater in the annual period and in both half-year periods, which are the result of mutual relationships between the physical qualities of these catchment areas and their climatic and hydrological characteristics. The results obtained also confirmed the impact of surface runoff and actual evapotranspiration on the spatial distribution of effective infiltration. With soil types and groundwater depth distributions being similar in the catchment areas, changes in relationships between components of water balance are caused by differences in the type of land usage. Application of the WetSpass model has made it possible to arrive at a more accurate assessment of groundwater recharge. The results obtained may be used for erification of recharge areas and values of effective infiltration, set as a boundary condition in groundwater flow models.

Implementation of the draft Spatial Information Infrastructure Act requires development of several administrative regulations. One of them is the regulation of the Council of Ministers on "the issue of methods and modes of gathering, updating and distribution of thematic databases - SOZO and HYDRO, development of standard cartographic works, based on those data as well as on the rules of co-operation and on competencies of entities responsible for its creation and updating within the transposition of the INSPIRE Directive to the Polish legal conditions". The group responsible for implementation of that task, nominated by the Head Office of Geodesy and Cartography (GUGiK), has also prepared technical standards for creation of hydrographical and sozological maps. Performed works included: a) Analysis of obligatory GIS-3/GIS-4 Technical Guidelines with respect to updating definitions of individual thematic objects. This stage of works mainly included elaboration of new, as well as increasing the level of details of object definitions, in connection with obligatory regulations and standards, in particular the Water Framework Directive and the Floods Directive. Definitions of individual objects were also updated, and the catalogue of elaborated objects was also enlarged. The analysis of obligatory legal acts and environmental criteria points to the necessity to update the thematic content of the hydrographical database, with special respect to: -. new monitoring system, classification of the quality and ecological conditions of water, - water protection system, water intakes and inland water reservoirs, - threats connected with extreme events (such as floods), - hazards related to inflows of pollutants into waters. b) Development of rules of updating thematic map components. The scope of works included the attempt to specify time frames when updating the components of both maps should be performed. Updating of SOZO and HYDRO databases is considered as a set of works and organisationaland- technical activities aimed at achieving consistency of the data resources with the reality. It is assumed that sozological and hydrographical data will be acquired for the entire country not later than by the year 2015. c) Development of a conceptual model of thematic data. At present, topographic data stored in the digital form in reference VMapL2 first edition databases have been used for supplying thematic map structures. A modification of assumptions of creation of thematic maps also refers to that aspect - it is proposed that reference databases of new edition become the basic source of supplying thematic maps. It is also assumed that an orthophotomap and a digital terrain model will become the basic components used in the process of creation of thematic maps of the new edition. This will allow to increase the accuracy of acquisition of particular classes of objects (DTM - location of watersheds, hydro-isobates, location of outflow-less basins etc., orthophotomap - location of hydrotechnical structures, ranges of water reservoirs etc.); both components may be also used for implementation of complex spatial analyses. However, the most important element of that idea is the achievement of coherence with the basic reference data required at the same time. Interoperability of both thematic databases requires the utilisation of works gathered by other state institutions, such as the Voivodeship Environmental Protection Inspectorate, the Institute of Meteorology and Water Management, the Polish Geological Institute, the Institute of Soil Science and Plant Cultivation, the Regional Water Management Board, the Sanitary and Epidemiological Stations, the State Forests etc. In the course of creation of updated concept of both thematic databases, the structures of SOZO/ HYDRO databases were also reorganised; numerous substantial as well as technological modifications were introduced in both databases. Among others, selected classes of objects, which had been considered separately, were combined in order to increase the transparency and coherence of the entire model, dictionaries of data, related to selected attributes were developed, a unified system of identification of every object introduced to the database was developed, presence of an attribute, which allows for storing the source object identifiers, originating from the reference database structures (such as Topographic Databases) were assumed. This will allow for harmonisation and exchange of information between the databases in the future.

The Topographical Database (TBD) is a nationwide undertaking implemented since 2003 by the Head Office of Geodesy and Cartography and by Voivodeship Marshals. Its aim is, first of all, to create modern resources of topographic data which will provide a base for various spatial information systems built and used by state institutions and organisations as well as by private companies and individual users. As a reference database, TBD is one of the most important elements of the national infrastructure of spatial information within the context of implementation of INSPIRE Directive of the European Commission. One of the principal applications of TDB is its utilization in crisis management, where high quality spatial information plays important, often key role. The data contained in TBD may be used, for instance, for realization of the following aims: m registration and presentation of dangerous objects on a map, m conducting demographic analysis in potentially endangered areas, m registration and presentation of public buildings, m planning distribution of assembly points of population, command centers, evacuation routes, m planning and coordinating approach to the catastrophe area, m simulation of spreading of flood wave, m estimation of potential damages depending on actions undertaken during the disaster (analysis of variants of actions) and estimation of damages afterwards. Realization of these aims is possible thanks to the scope of content and accuracy of data contained in TBD: m digital model of the terrain surface, m ortophotomaps with resolution of the order of 0.5 meter, m vector data typical for spatial GIS databases containing descriptive attributes, m image of topographical map in digital raster form or in the form of plotter printouts from the database. In the paper examples of data available from TBD are discussed and general assessment of usefulness of individual information contained in TBD is presented supporting the most typical actions of crisis management centers. Attention was also drawn to methodological and technological aspects of taking advantage of TBD.
