Mr. Havel, at our last meeting, you said you started out as a drummer in a big beat band and you also wrote lyrics. How long is the journey from music to water manage-ment and environmental protection? It is, of course, a long journey and has been lined with a number of unrepeatable coincidences and life situations, which ultimately… Read more »

Investigation of hyporheic biofilms of the Vltava river in Šumava national park with regard to juvenile rearl mussels, their feeding requirements and sufficient oxygen saturation of interstitial water
The research on biofilms has been ongoing within the project “Strengthening and protection of the pearl mussel population in Šumava NP” since 2018, when suitable research methods and procedures for studying the development of biofilms on hyporheic sediments (e.g. incubation of glass beads versus incubation of river sediment, granulometric survey of bottom sediments) were sought and tested, and the most suitable locations for the placement of experimental facilities were selected.
Study of the effectiveness of the small municipal sourcess sewage sludge extensive stabilization for their use as a fertilizer
The article is devoted to the presentation of partial results of a study aimed at determining the potential use of extensive sludge dewatering technology for small municipal WWTPs (up to 1000 PE) in the conditions of the Czech Republic. The study has shown that the use of technology based on extensive sludge dewatering and their stabilization in sludge dewatering reed beds with suitable wetland vegetation can be an alternative to other technologies. Especially in combination with constructed wetland (CW) based WWTPs, which are characterized by lower sludge production.
The authors during the research of the relationship between certain impacts and housing prices were inspired by the knowledge and results of processed literature. Concretely by the characteristics which had an affect on housing prices throughout the World. The city of Brno was chosen as a suitable place of research.
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).
Interview with Mrs. Heide Jekel, President of the International Commission for the Protection of the Elbe
The day you receive this issue of VTEI magazine, it rarely coincides with the date of the Magdeburg Seminar, organized by the International Commission for the Protection of the Elbe (ICPOL). We therefore take this opportunity to bring you a brief interview with the current President of this Commission, Mrs. Heide Jekel. You can find her biographical profile under the interview.
The article describes a method for determining the erodibility of incohesive agricultural soils by means of the critical shear stress measuring. The “Jet Erosion Test” (JET) was used to determine the critical shear stress. The mea- surement was performed using a modified Mini-JET device. The device is very suitable for field measurements, because it is small, light, requires a relatively small amount of water, and can be operated by single person. The principle of measuring the critical shear stress of the soil is based on monitoring the rate of erosion crater formation by the action of a water jet of known kinetic energy. Based on the erosion crater development, the erosion parameters of the soil, such as the critical shear stress and the erodibility coefficient, can be calculated.
The article focuses on the water industry sector. It deals with the development of drinking water supply in Šumperk town from the Middle Ages to the 1960s. According to the water supply network development, the text is structured into individual chapters, focusing on the interesting period of the late 19th century, when a municipal water plant was established. The water plant was also the first company managed by the city council at its establishment. It was an excellent good practice example for similar towns in the Czech lands, both technologically and operationally. Subsequent chapters focus on expanding the water supply network, reservoirs, and intake areas, which had to be sized for the increasing water consumption associated with the city‘s dynamic development in the late 19th and first half of the 20th century. The final chapter summarises the development of the municipal waterworks project from 1945 until the year when the town of Šumperk was connected to the water intake sources from the Kouty-Šumperk group water supply system. The paper is an inspiring retrospective look into the history of the municipal water supply. It can also be a helpful comparison with the current state, building possibilities and limits of the water supply infrastructure.
Modern municipal services in solid waste management usually include cleaning and cleaning of public spaces, collection, transport, recycling and disposal of generated waste. Solid waste management services are among the most expensive and complicated municipal work systems for the public. At the same time, it can also be the least awarded communal service. Water, electricity, firefighting and police protection meet the daily needs of residents and businesses fundamentally and immediately. Therefore these services are given a much higher priority by the community and its leadership. Waste management services are usually one of the most minor „fragrant“ public services, but their flawless functionality and efficiency have far-reaching implications.
In the years 2014–2019, there was a historic drought in the Czech Republic. The Department of Hydrology and Hydrogeology of the T. G. Masaryk Water Research Institute has been carrying out long-term hydrological and hydrogeological observations in the upper Metuje basin where this drought manifested itself significantly. The upper part of the catchment area of the Metuje River is located in the Police Cretaceous basin geological formation.
Hodnocení erozní účinnosti deště je v současnosti těžištěm výzkumu v oblasti stanovení erozního ohrožení půdy. V rámci empirického modelování pomocí modelů rodiny USLE (the Universal Soil Loss Equation) je erozní účinnost deště reprezentována tzv. R faktorem, jehož hodnotu lze stanovit řadou doporučených postupů. Tento článek představuje možné alternativní způsoby určení hodnoty R faktoru na základě ročních a měsíčních sum srážkových úhrnů.
S překotným vývojem v oblasti geoinformačních a komunikačních technologií se objevují nové možnosti mapování a kvantifikace erozních procesů způsobených přívalovými srážkami. Pro získání relevantních výsledků je důležitá kvalita, hustota a rozsah vstupních dat. Rychlý a poměrně levný sběr přesných geodat umožňují bezpilotní letecké prostředky (UAV – z anglického Unmanned Aerial Vehicle). S využitím metod digitální fotogrammetrie je možné z pořízených leteckých snímků rekonstruovat morfologii terénu odpovídající času měření.
This study presents interim results of an evaluation of a potential climate change impact on the preservation of drinking water demand provided by water reservoirs in the timeframe of the year 2050.
