Methodical conditions of the ecological status assessment of rivers on the basis of their hydromorphological elements

The Water Framework Directive requires all member states to make an as-sessment of the ecological status in natural, heavely modified and artificial water bodies. The evaluation includes biological elements, physico-chemical compounds of the water and hydromorphological elements (hydrological regime, river conti-nuity, river morphology and valley). In 2009 the Central Inspectorate of Environ-ment Protection in Warsaw accepted a new method of monitoring of the hydro-morphological elements in rivers (MHR), prepared by the authors. The MHR method involves the investigation of main rivers in all Polands (4508) identified water bodies, with a total length of about 75 000 km. This required a review of the investigation methods developed by polish and other member states in 1980-2000. Many international and local regulations, the accessibility of topographic and thematic maps in different scales, as well as data bases for rivers and canals were analysed. The possibility of preparation of different methods for rivers with different catchment areas, in different landscapes, categories and substrate types were studied. The methods used for the assessment of biological elements was examined and shown not to provide adequate information for the investigation of the hy-dromorphological elements. The assessment was based on the characterization of four elements which were ...

Monitoring and assessment of hydromorphological elements in polish rivers

The main ideas of a new MHR method for hydromorphological river survey and assessment were presented. It is a combination of the substance of the Water Framework Directive 2000/60 and the European standard EN 14614. It takes into account the existing polish data basis, regulations from the Minister of Environ-ment, the Inspire and Reporting directives and the existing experience completed in the Central European countries by the monotoring and assessment of hydro-morphological elements in the last 25 years. The method is strength on the works done in Poland for the implementation of the Water Framework Directive.The hydromorphological river assessment uses a hierarchic system which allows for the calculation of the ecological quality index. The system's basis is built by four elements: hydrological regime, river continuity, river morphology and the valley. Every element is described by some parameters and these by selected attributes. The separately calculated ecological quality index of elements and parameters allows to discover why the good ecological status was not obtained. The average index for all elements is the index of the water body. The investigations are based on existing topographical and orthophoto maps, data basis of the Institute for Meteorology and Water Management and the river ...

THE EFFECTS OF NATURAL DISASTERS AND ADVERSE WEATHER CONDITION IN THE AGRICULTURE OF THE OPOLSKIE PROVINCE

This work presents the analysis of appearing the natural disasters in opolskie province in years 2008-2010. Dates was received from protocols of losses from administrative districts and cities which rose as a result of disaster and/or adverse weather conditions. On the basis of this information analysis of the scale of this phenomenon have been done. With the use of the statistical test chi-square the comparing of the number of farms embraced with disaster, the size of losses in the zloty and the degree of damage in % and numbers of farms applying for credit in the period of three years. Data concerning the frequency of appearing the natural disasters and adverse atmospheric phenomena in individual local governments on the map of the Opole province was presented. Carried analyses and statistical comparisons are showing that this kind of phenomenon appearing more and more often and defines the areas which suffered particularly in years 2008-2010. Basic of the map it is possibility to isolate north and north west area of our region as the most exposed to losses with adverse atmospheric phenomena and/or natural disasters and the south part of the province where the scale of these phenomena is lesser. ...

DYNAMICS OF CHANGES IN TERMS OF SOCIO-ECONOMIC MUNICIPALITIES DISTRICT KRAKOW IN THE YEARS 2010-2014

The article presents the dynamics of socio-economic changes in the rural district of Krakow. For the purposes of analysis defined the phenomenon of socio-economic development with the help of variables clustered in four groups of information. Analyzes selected demographic factors, factors of an economic variables describing the social infrastructure and technical support. The analysis of changes in the analyzed period was based on the procedure for making typological delimitation of the communes of the district of Krakow and the municipalities homogeneous group. The values of the variables taken for analysis from sources of Official Statistics (GUS) from the years 2010-2014. As a result of the procedure typological defined types of municipalities homogeneous in terms of socio-economic conditions in the studied years, based on the selected diagnostic features. It presents the ranking of municipalities, and compared the dynamics of socio-economic development in the period in each rural district of Krakow. ...
