Hydromorphological valorization according to Water Framework Directive is an element of support biological evaluation of surface water's ecological state. Ecological state of rivers is connected with number and diversity of species that live in them. Biodiversity of aqueous environment is depended on changes occurring in the river environment characteristics what is mostly connected with riverbeds conversions. In this article present the results of hydromorphological valorization of section of The Bystrzyca River below Mietkowskie Lake together with its old bed. Artificially built drop channel that carries away water from the reservoir (1,4 km), old riverbed (2,2 km) which had conducted water before the dam was built and the section of river that was created by the connection of new section with The Bystrzyca old riverbed were analysed (1,4 km). The analyzed a total of 25 sections of river, 200 meters each. The naturalness degree of individual sections was evaluated on the basis of Ilnicki and Lewandowski methodology. Ecological evaluation criteria have taken into consideration riverbed morphology, river hydrology, water quality, tree cover, aquatic and banks vegetation, riparian zone and the valley land management. From conducted research follows that with increasing the distance from the reservoir the naturalness category of The Bystrzyca ...
The study aims at presenting the spatial policy of communes located along the course of the river Bystrzyca in the Wrocław district, with regard to the protec-tion of the environmental values of the watercourse. The documents analysed in-clude the studies of determinants and directions for the spatial management applied in the Mietków, Kąty Wrocławskie and Sobótka communes. The articles were studied with regard to identifying the values of the natural environment with special emphasis on water resources, protecting the aquatic environment, and further directions for water protection. The study also focuses on the planned spatial development for investment in the vicinity of the Bystrzyca Valley Landscape Park as well as within its area, with regard to the area planned for investment. ...
