The paper discusses problems in water management planning, referring especially to the spatial data needed in this process. Data collected during implementation of the Water Framework Directive are mentioned, which are the basis for assessment of aquatic environment status, as well as for preparation of programs of measures and, consequently, of river basin water management plan. On the other hand, the Directive on the assessment and management of flood risk in force since 2007 requires preparation of flood hazard maps, flood risk maps and flood risk management plans. These documents can be included in the river basin water management plan, and the deadlines for preparation and updating them can be synchronized.

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.

After accession to the European Union, Poland commenced to implement the Community water policy. The main objective of the Water Framework Directive (WFD) is to achieve a good ecological status of surface and ground waters by 2015. The achievement of such status requires realization of investments as well as planning activities covering such spheres as planning of land use and utilization of natural resources. Including a lot of issues within one directive, so-called framework directive, requires application of modern tools, including GIS-tools enabling evaluation of the status and effects of planned programs. These tools allow current implementation of changes and conducting of spatial analysis of mutual impact of environmental components. The role of GIS-techniques in implementation of the WFD is double, on one side they are utilized for preparation of information layers e.g. river basin characteristics, chemical and ecological status of water bodies, reference conditions etc., and on the other side, preparation and delivery of GIS shapes needed for reporting. Up till now, the following information layers result from WFD implementation: responsible administrative bodies, water balance areas, protection areas, surface water categories, types and bodies, including transitional and coastal waters, ground water bodies and man-made pressures. Inventory of waters in accordance with EU guidelines covers the whole territory of Poland and is harmonized with the activities of neighboring countries. Additional value of the numerical data is the possibility of their utilization by institutions and social parties involved. Public participation is obligatory for the institutions which are involved in the implementation of the programs covering measures within the river basins.
