Water status elements in determining ecologically acceptable flow
Example of a catchment, pipes and discharge resulting from the operation of a small hydropower plant Achieving good ecological status and water abstraction are often seen as activities with conflicting objectives. The aim of the study was to determine whether, despite water abstraction from Alpine watercourses, we can achieve good ecological status and which pressure […]
Updating methodologies for assessing ecological status based on biological elements
Updating the methodologies for assessing the ecological status and classifying surface water bodies on the basis of biological quality elements, as drawn up in 2013 As part of surface water management, methodologies for assessing the ecological status of water bodies must be developed for each biological quality element (BQE). Methodologies for assessing ecological status were […]
Identification of fish-type watercourses in the Dinaric and Po Valley hydro-ecoregions
With a view to developing methodologies for assessing ecological status in accordance with the Water Framework Directive in Slovenia, we have identified fish types in watercourses within the Dinaric and Po Plain hydro-ecoregions. The fish types were identified on the basis of similarities in fish communities. The description of fish communities (fish types) serves as […]
Determining the maximum ecological potential of retention basins
Methodology for assessing the ecological potential of reservoirs based on phytoplankton and benthic invertebrates; determination of maximum ecological potential Water bodies whose characteristics have been significantly altered by physical changes caused by human activity are referred to as heavily modified and artificial water bodies. The ecological potential of heavily modified and artificial water bodies is […]
Factors contributing to bacterial and viral infections in clams
As part of the targeted research project, samples of blue mussels – both those farmed in mussel beds and those growing wild along the Slovenian coast – were subjected to chemical and microbiological analysis over a one-year period. IZVRS identified sources of pollution and monitored the chemical parameters of seawater. About the project Client Public […]
Remote sensing of the hydromorphological characteristics of large rivers and the effects of pressures on biological communities
Remote sensing of the hydromorphological characteristics of large rivers and assessment of the impact of anthropogenic pressures on communities of benthic invertebrates and fish in large rivers in Slovenia The aim of this study is to investigate whether, within the SIHM system, data on the hydromorphological characteristics of major rivers obtained through field surveys be […]
