From the world of water management

Vztah scénického pohledu a hodnoty rezidenční výstavby

, and –

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. Firstly, photographs of various residential buildings were made. Secondly, those photographs were filtered. The buildings, which have shown certain significant abilities, were chosen. Subsequently, together with Delphi method, a questionnaire with concrete questions was made. Also a circuit of experts was determined and the questionnaire was sent to them. These experts work either in the branch of economy, building industry and real estate or in an uncategorized branch. Addressed experts filled the questionnaires and sent them back. Subsequently, an opinion exchanging phase of evaluation from each questionnaire took place.

Interview with RNDr. Radim Tolasz, Ph.D., climatologist of the Czech Hydrometeorological Institute

and –

Today, one individual cannot quickly mitigate the current impact of climate change that the entire world is facing by changing their behaviour. However, the promotion and spread of education is one of the main keys to making positive changes in a significant part of the population. In an interview for VTEI, the Czech representative in the Intergovernmental Panel on Climate Change (IPCC), climatologist RNDr. Radim Tolasz, Ph.D., from the Czech Hydrometeorological Institute (CHMI), describes further steps to mitigate the effects of climate change or, for example, his own first professional experience after 1980.

Development of pond locations in the Polabí lowland since the mid-19th century – part 2 – Poděbrady region

–

This article presents the results of research on landscape changes in the Poděbrady region as part of the Polabí lowland, where there have been significant changes in the location of ponds. The area of all types of ponds (according to stability) makes up 3.17 % of the Poděbrady region. Ac-cording to their occurrence in the area in 1836/1852–2022, the ponds (or their parts) were divided into disappeared, continuous, and new. Disap-peared ponds have the largest representation – about 60 % of the total pond area according to stability. They are followed by continuous ponds, with the minimum area represented by new ponds. The historical or (more precisely) disappeared ponds were more robust than the present ones, i.e., they had a larger average size. Analyses show that almost three-quarters of the disappeared ponds have been replaced by arable land.

Fundamental revision of the Urban Waste Water Treatment Directive provokes conflicting reactions from European Union member states

–

Council Directive 91/271/EEC of 21st May 1991, the Urban Waste Water Treatment Directive (UWWTD), entered into force 32 years ago, which is a respectable age for a legal regulation. Since then, through the consistent implementation of its requirements, good results in water protection have been achieved in practice. Between 1990 and 2014, there was a reduction in the amount of pollutants in treated and discharged urban waste water for organic pollution expressed as BOD5 by 61 %, for total nitrogen by 32 %, and for total phosphorus by 44 %. The extensive support pro-vided to cities and municipalities from EU financial instruments as well as from national sources and the relatively strict application of sanctions have led, according to data published by the European Commission (EC), to the fact that currently 98 % of waste water in the EU is effectively collected and removed of and 92 % properly treated. Until now, the Directive’s requirements have primarily focused on centralized systems for the collection, removal, and treatment of waste water in agglomerations producing loads at the level of 2,000 population equivalent (PE) and more.

Interview with Mgr. Petr Hladík, Minister of the Environment

–

The Minister of the Environment wants to give people the opportunity to live in harmony with nature, and by that he does not mean just planting trees on city streets. Why does Petr Hladík call the Ministry of the Environment the Ministry of the Future? The use of rainwater, solar panels, and deposit PET bottles no longer have to represent an excessively progressive approach, but a standard for returning to our planet at least the minimum of what we take from it. Grey water subsidies? Why should we want it and what will we actually benefit from it? The new Minister of the Environment, Petr Hladík (KDU-ČSL), answers these questions for VTEI journal.

Technical Heritage of the Elbe-Vltava Waterway

–

From 8th November 2022 to 31st January 2023, an exhibition entitled “Technical Heritage of the Elbe-Vltava Waterway” took place in the atrium of the Faculty of Civil Engineering of the Czech Technical University in Prague (CTU). The exhibition included exhibition panels, an interactive model of a weir lock, a video projection screen, and a stand with a web application www.lvvc.cz. The exhibition mapped the history and development of this 324 km waterway since the beginning of the 19th century, and it is expected to continue as a travelling exhibition.

Landscape changes in selected locations of the Polabí lowlands with a focus on wetlands

–

This article presents three typologically different sites from Polabí where large-scale wetland sites were located in the past, including ponds. These sites were chosen in order to present disappeared floodplain meadows, disappeared “field” wetlands, disappeared ponds or pond systems, and, simultaneously, to present sites where wetland habitats have been at least partially restored. The main aim was to present easily accessible archival maps, on the basis of which it is possible to assess the spatio-temporal dynamics of wetland habitats in the places of disappeared wetlands with regard to their possible restoration.

Planned restoration of aquatic ecosystems in Prague 4

–

Prague 4 district in accordance with the National Action Plan for Adaptation to Climate Change [1], Concept for Protection from the Effects of Drought of the Czech Republic [2], Strategy for Adaptation of the Capital City of Prague to Climate Change [3] and Methodology for Rainwater Management in the City [4, 5], similarly to other progressive-minded parts of Prague, is preparing investment actions to support and strengthen green-blue infrastructure in the city. One of the most visible measures with truly demonstrable effects on the support of biodiversity and water retention in the landscape is the restoration of aquatic ecosystems. In the case of the capital city of Prague and its most populous district of Prague 4, these are mainly the restoration of canalized (straightened or piped) streams, or desilting, strengthening or comprehensive restoration of ponds and small water reservoirs in a highly urbanized landscape. A specific area is newly emerging bodies of water in places where water naturally tends to be retained after longer periods of rainfall and the area thus cannot be used for any other purpose, or even in places where there was no body of water before (although here in the narrower sense of the word it is not restoration). For such areas created by human intervention in order to strengthen the diversity of aquatic and wetland vegetation, the name artificial aquatic biotope has been adopted. Let us have a look at the differences and specific pitfalls of individual restoration using three specific examples.

Dewatering sewage sludge using sludge drying beds with wetland vegetation, the so-called Sludge Treatment Reed Bed units

and –

At present, the problem of waste disposal is growing worldwide; its secondary use is therefore more than desirable. A pressing problem for many small municipalities that need to build or reconstruct a wastewater treatment plant (WWTP) is solving the issue of processing the resulting sludge and its stabilization, sanitation, and further application. It is not unusual for small municipal WWTPs to lack a complete in-situ sludge management (including dewatering etc.). Sewage sludge is thus often pumped out at high cost and transported to a large WWTP. The main goal for the real application of sewage sludge is to prevent future damage to soils, plants, and the health of animals and people. For this reason, taking into account the substances currently present in the sludge (e.g., organic micropollutants), it is advisable to sufficiently pre-treat the sludge, not just sanitize it to eliminate above-limit microbial pollution.

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. 

On the issue of authenticity of water management structures

–

Authenticity, in the sense of credibility or truthfulness, is one of the key categories in heritage management. This paper focuses on the question of authenticity in relation to industrial heritage, specifically water management structures. In the case of these structures, emphasis is usually placed on 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 authenticity as a consequence of historical evolution. The 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 legal 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.

Interview with Ing. arch. Eva Dvořáková and Ing. arch. Tereza Bartošíková, Ph.D., about protection of technical and industrial cultural heritage in the Czech and Slovak Republik

and –

As part of the December issue of VTEI, which is entirely devoted to the topic of technical and industrial cultural heritage and the “Programme of applied research and development of national and cultural identity (NAKI II)” of the Ministry of Culture, we asked for an interview with two specialists in this field, Ing. arch. Eva Dvořáková from the National Heritage Institute (Národní památkový ústav, NPÚ) and Ing. arch. Tereza Bartošíková, Ph.D., from the Monuments Board of the Slovak Republic (Pamiatkový úrad Slovenskej republiky, PÚ SR).

Use and popularisation of historical and current water management sources of information for the development of an environmentally friendly society

–

Since time immemorial, research in all scientific fields has brought countless new information and broadened the spectrum of current knowledge. In the past, research was made more difficult by the then possibilities of disseminating newly acquired knowledge. Many scientists in the world have asked
the same questions, proposed and tested similar hypotheses, obtained similar scientific results, and reached their own unique conclusions. The problem was the very limited possibility of sharing this new information, thus the possibility of their mutual use and very often their preservation and availability to
future generations. It is safe to say that in the history of science, a huge amount of knowledge and information was discovered that was not used enough, was discovered repeatedly, or was completely lost.

The current version of the BILAN model

and –

BILAN je celistvý konceptuální model v denní/měsíční struktuře (schéma je uvedeno na obr. 1), simulující složky hydrologické bilance na povodí. Přestože jeho vývoj byl nastartován ve VÚV TGM již počátkem devadesátých let minulého století, jde o model, který je v České republice stále standardně používán a zůstává přístupný laické i odborné veřejnosti. Například je nedílnou součástí řešení aplikace/systému HAMR [1], ale byl použit i jinde [2–4]. Mezi hlavní výhody modelu oproti jiným řešením patří interní kalibrační algoritmy, možnost přímého vkládání dat o užívání vod a nízká výpočetní náročnost vhodná pro variantní simulování (např. dopadů klimatické změny na vodní režim).

Annotation of the exhibition Irrigation – rediscovered heritage, its documentation and popularization

, and –

As a response to landscape drainage in the modern era, caused by the intensification of agriculture, the drying up of ponds, and land reclamation activities, interest in the opposite process has reappeared, i.e. irrigation. Existing irrigation systems, at present often non-functional and preserved only in parts, have become the subject of interest for this project which tried to capture the historical development of this specific water management field as well as part of the industry associated with the implementation of irrigation and the production of soil irrigation equipment.

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.
