Water Quality and State of Aquatic Invertebrate Populations in Small Watercourses in Prague

The aim of this paper has been to evaluate the ecological status of small watercourses in the capital city of Prague by analogy to the evaluation of water bodies pursuant to Directive 2000/60/EC. A total of eight sites were selected at seven watercourses (Šárecký, Dalejský, Radotínský, Libušský, Kunratický, Botič and Rokytka Streams). Both sections that are semi-natural and those that have been restored in various ways were selected. From May 2017 onwards, annual sampling of chemical indicators took place in selected sites and a standard multihabitat method was used to take samples of aquatic invertebrates (macrozoobenthos).

Significant adverse effects of measures for the use of heavily influenced water bodies: experiences and examples from abroad

In April 2018, an international workshop was held in Brussels to assess the significance of adverse impacts of planned measures for use or wider environment of heavily modified and artificial water bodies. This issue is related to the implementation of the Water Framework Directive 2000/60/EC and the harmonization of the level of good ecological potential among EU Member States.

Characteristics determining the stability of woody debris on the example of Morava River in the Litovelské Pomoraví

Wood is an important part of streams, affecting their hydraulic, morphological and biological features. For the stream management and flood risk reduction it is important to know the characteristics that increase the stability of wood and prevent its flushing at high water stages.
