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).

The assessment of the status of surface water bodies in the Czech Republic for the period 2013–2015

This article aims to present to the general public the results of the assessment of the ecological status/potential and chemical status of surface water bodies categories “river“ and “lake“ for the period 2013 to 2015 in the Czech Republic. The assessment was carried out in 2017 by the Water Research Institute of T. G. Masaryk, p. r. i.

Evaluation of the impacts of drought on aquatic and water-bound organisms in surface water bodies

Within the framework of the sub-task “Evaluation of the impacts of drought on aquatic and water-bound organisms in surface water bodies“ a project involving activities to support the state administration in the drought issue in 2016 was prepared mainly a review of the potential impacts of drought on individual elements and indicators of water status assessment.

Surface water body typology category river in the 1st and 2nd cycle of River Basin Management Plans and its consequence to ecological status assessment

Surface water body delineation and setting a typology are one of the initial steps during Water Framework Directive implementation (WFD) [1]. The first delineation and typology was prepared in 2004–2005 for the first plans, but all the results were significantly changed in the second cycle 2009–2010.
