Dynamics of micropollutant loads into water supply reservoirs Vír I, Opatovice and Ludkovice

, , , , , and –

Pesticides are still an important group of substances involved in surface water pollution. Their increased occurrence in watercourses in the agricultural landscape is mainly linked to rainfall-runoff conditions, types of cultivated crops, and methods of agricultural management. In order to capture these factors, passive sampling techniques were chosen for the assessment of the load of these substances in selected catchments of water supply reservoirs in the administration of Povodí Moravy State Enterprise. These techniques consist of continuous exposure for several weeks with gradual (integrative) capture of pollution on suitable sorbents. The POCIS (polar organic chemical integrative samplers) were chosen in this work – widely used samplers suitable for capturing polar organic substances. They were applied in eight consecutive sampling campaigns to cover the entire growing season.

Potential of areas protected for surface water storage to mitigate the impacts of climate change on drinking water supply

, , and –

In the Czech Republic, areas morphologically, geologically and hydrologically suitable for surface water storage to mitigate the adverse effects of floods and droughts are defined through the General Plan for Surface Water Accu-mulation Areas. In the context of climate change, these locations create potential for possible adaptation measures. This article describes the assessment of the potential of selected sites for water supply under climate change condi-tions by means of hydrological and water balance modelling.

Presentation of some of the results of a research project mapping the development of the construction of elevated water tanks in the Czech Republic

and –

This paper presents a summary of some of the results of the research project,
“Water towers – identification, documentation, presentation, new utilization”,
(DG18P02OVV010), which has been implemented since 2018 as part of the Programme for the Support of applied Research and Development of National and Cultural Identity for 2016–2022 (NAKI II) of the Ministry of Culture of the Czech Republic. In terms of content, it follows on from articles from previous years published in this periodical, but clarifies and supplements the issues of technical terminology and typology established at its inception based on the knowledge gained during the project. Furthermore, it presents general results of the records of the structures of elevated water tanks and focuses on a brief description of the historical development of these structures in our territory.

Irrigation – rediscovered heritage, its documentation, popularisation and protection based on the example of historical meadow irrigation systems

, , , , , , and –

Irrigation systems were built and have operated mostly as part of a larger or
smaller functional complexes. Their significance, also from the point of view
from potential heritage protection, thus increases with the identification and
documentation not only of solitary structures but, in particular, of entire systems / functional complexes with descriptions of interrelationships between them. Independent objects or structures do not need to be particularly exceptional, although their involvement in the wider functional complex can create a uniquely undertaken solution. In the field of water management, criteria such as typological value, value of technological flow, authenticity of form and function, value of technological and systemic links with an overlap to agriculture and industry are especially important. This article provides information on possibilities of using traditional methods of historical and archive research and documentation of localities, and at the same time using modern tools for systems over a more extensive area, including methods of digitisation and processing of documentation.

On the issue of authenticity of water management structures

–

Authenticity, in the sense of credibility or truthfulness, is one of the key categories of heritage management. This paper deals with the issue of authenticity in relation to industrial heritage, specifically water management structures. In the case of these structures, emphasis is usually placed on the authenticity of function, but two further types of authenticity are equally important: authenticity of material substance or form (in relation to the original design and the structure built on its basis), and, on the other hand, authenticity as a consequence of historical development. This paper presents an analysis of four model examples of water management structures that are either legally protected heritage sites or have been proposed as candidates for heritage protection. The analysis of their heritage values provides insights into the individual categories of authenticity and enables the formulation of principles for managing sites of heritage value.

Fish stocks of water elements in heritage protected complexes

, and –

The aim of this article is to present the results and conclusions of research which focused on recommending an appropriate approach for the creation and maintenance of fish stocks in various types of water elements, from small ornamental pools to formal water elements and large close-to-nature fish ponds. These elements form part of cultural monument complexes and heritage protected settlements (especially historic gardens and chateau parks, religious complexes, village and urban heritage reserves). Detailed results are described of a twoyear investigation of various types of water elements located in Kroměříž gardens, Červené Poříčí Chateau, and the former monastery in Osek, near Teplice, as examples of cultural monuments and their water elements. Issues of possible management of fish stocks, modifications of the aquatic environment to ensure stable conditions for fish farming, and the reduction of negative interaction of pollution and excessive or inappropriately chosen fish stocks and aesthetic perception of water elements are discussed. The results of the field investigations
have shown an unsatisfactory state of virtually all locations due to water
eutrophication, overgrowth of vegetation in some water elements, unregulated interventions in fish stocks, and uncontrolled fishing resulting in the reduction of predatory species population and the occurrence of invasive species. At the same time, a relatively low awareness of the possibilities of regulating fish stocks and of the principles of sustainable maintenance have been found.

The construction of large hydraulic structures in the context of ideas and ideologies

and –

This paper deals with some aspects of the relationship between man and water demonstrated via the example of large hydraulic structures constructed in the Czech lands. Based on this relationship, principles of the practical functioning of ideas and ideologies, including religion, can be presented. It is not just about “pagan” cults, aiming directly at worshipping water as a living being. Christianity also significantly influenced the framework in which water management operated across the centuries and, at the same time, new ideas associated with the Enlightenment and the Industrial Revolution during the 18th and 19th centuries. A key part of the paper is focused on the topic of the construction of large hydraulic structures in the 20th century, which was particularly intensive in its second half. It also mentions political, ideological, and natural
changes which were, at the beginning of the 21st century, reflected in man’s relationship with water resources and the possibilities of influencing them.

River ferries on old topographic maps

, and –

Medium and large rivers have been a major obstacle to historic trade routes and trails. River ferries were one of the main ways to cross them, so their locations were considered points of strategic importance. Using old topographic
maps of Austrian military mapping from 1763–1768, 1836–1852, 1876–1880, Prussian military maps from 1825 and 1877 and Czechoslovak military maps from 1953–1957, we systematically located ferries throughout the current territory of the Czechia.

A review article of Rapid Small-Scale Column Tests

and –

Rapid Small‑Scale Column Tests (RSSCTs) can be used for quick and easy laboratory verification of adsorption efficiencies on various adsorbents. The selection of adsorbent is the most important aspect when incorporating adsorption technology into the operation of the drinking water purification plant, or the wastewater treatment plant. The tests are carried out on laboratory‑scale, which minimizes material and operating costs. The article focuses on the adsorption on granular activated carbon (GAC), as it is the most commonly used type of adsorbent.

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

, , and –

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

, , , and –

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.

Water quality and state of aquatic invertebrate populations in small watercourses in Prague

, and –

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).

Mini-JET device as a tool for determination of soil erodibility characteristics

, , , and –

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.

A retrospective view of the Šumperk water supply system up to the 1960s

, and –

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.

Municipal waste management in the light of new regulations

, and –

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.

Drought in the Upper Metuje Basin in 2014–2019
