The paper discusses the use of GIS tools and spatial information for defining significant anthropogenic impact and its effect on the waters of Polish rivers. In the EU the basic legal act regulating the issues of protecting water resources and ecosystems dependent on water resources is the Water Framework Directive 2000/60/WE (WFD). According to the requirements of the above Directive, EU member countries will have to achieve good status of surface waters by the end of 2015. Evaluating the effects of anthropogenic pressure on water environment is the first step conditioning future remedial actions. The identification of significant impacts was carried out with the use of GIS technology, which was in accordance with the guidelines for implementing RDW in EU member countries. The paper presents recommendations of the Water Framework Directive as regards the analysis of anthropogenic pressure. In order to carry out this analysis geospatial information was necessary. Some of the data were prepared within the framework of previous stages of RDW implementation, while the remaining data were obtained especially for the purposes of the above mentioned analysis. The paper presents this data as well as the methodology adopted for identifying significant anthropogenic impacts. The basic spatial unit for which the analysis was carried out was so called .aggregated part of surface waters. (SCWP). This term stands for the area that encompasses several adjoining sub-basin areas of similar character, identified for the purposes of water management planning. Also, examples of results of GIS analyses are provided, performed with the use of data from Regional Data Bank that was created and is managed by the Central Statistical Office (GUS). Additionally, the paper describes indicators used for the assessment of morphological changes as well as methods to calculate selected examples of indicators. The result of spatial analyses is final assessment of possible obstacles to achieving good status of waters by the end of 2015, prepared on the basis of information on hydrology and morphology of watercourses as well as on causative factors.

Przedstawiono wyniki badań nad wielkością ładunków zanieczyszczenia wód Wisły przeprowadzonych w okresie 1992-2001. Badania prowadzono w trzech punktach pomiarowych: w Krakowie {km 63,7), w Warszawie (km 510,0} i w Gdańsku (km 926). Pomiarami objęto 50 parametrów jakości wody. Pobór prób dokonywany był w latach 1992-1997 z częstotliwością jeden raz w tygodniu, a od roku 1998-dwa razy w miesiącu. W ocenie wielkości ładunków wykorzystano codzienne pomiary wielkości przepływu w rzece w badanych przekrojach wykonywane przez IMGW.

The water economy - in the present-day understanding of that term -has begun to develop in the latter part of the XIX c., when in spite of annexation of Polish territory the engineers have undertaken attempts at organization of investigations and have launched a number of water investments. After the independence has been regained those initiatives have been taken over by state agencies, research institutions and academies. In January 1929 there was held in Warsaw Engineering College the I Polish Hydrotechnical Congress which has created the Association of Water Economy. In result of Association's activity has been brought into being the scientific and technical monthly magazine „Gospodarka Wodna" (Water Economy). After some tens of years during which the magazine has been edited it celebrates now the seventieth anniversary of the work. In the paper there is presented the origin and development of the magazine.

Ocenę zmian jakości wody Wisły w powyższym okresie dokonano na podstawie wyników pomiarów przeprowadzonych w trzech punktach pomiarowych (km 63,7 - Kraków, km 510,0 - Warszawa, km 926,0 Gdańsk). Dotyczyła 8 wskaźników zanieczyszczenia (BZT5, amoniak, azot ogólny, fosforany, fosfor ogólny, chlorki, siarczany, chlorofil). W tabelach i wykresach załączonych do opracowania podano wartości minimalne, średnie t maksymalne badanych wskaźników w kolejnych latach.

The presented in the paper evaluation of changes in waterquality of the Vistula in the mentioned above period has been made on the basis of results of measurements carried out in three measurement points (km 63,7 - Cracow, km 510 - Warsaw, km 926 - Gdansk) and comprising eight parameters (BOD 5, ammonia, total nitrogen, phosphates, total phosphorus, chlorides, sulphates, chlorophyl). !n tables and on diagrams attached to the paper have been shown the minimum, mean and peak values of measured parameters in successive years of the period.
