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

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.

Fish stocks of water elements in heritage protected complexes

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.

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

 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… Read more »

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.

Fidings from testing of selected biochemical products to the heritage sites water elements environment adjustment

The article is focus on the presentation of knowledge from testing of selected biochemical preparations for the treatment of the environment of water elements of historical gardens and parks and cultural monuments.

Environment quality of water elements of heritage protected areas

Water elements represent a significant part of the environment of cultural heritage sites, conservation zones and areas. To fulfil the required functions, which may include social, historical, recreational and educational, but also environmental functions; it is necessary to ensure their corresponding target state.

Potential of the nature-friendly measures application for water retention in the landscape and improvement of the ecological status of water bodies

An analysis and assessment of the nature-friendly measures potential for water retention in the landscape were carried out as a part of the work on the concept of protection against drought impacts in the Czech Republic.

Non-invasive and economical techniques of water elements environment quality and maintenance solution in the frame of historical monuments care – presentation of the project

The research team from the Brno office of WRI and reference laboratories in Prague started from March 2016 work on a research project DG16P02M032 “Non-invasive and economical techniques of water elements environment quality and maintenance solution in the frame of historical monuments care”.

Constructed wetlands – design parameters, operating experiences and intensification possibilities

Horizontal and vertical flow constructed wetlands belong among frequently used near-natural methods of treatment of wastewater from small municipalities in the Czech Republic. They consist of one or more filter fields connected in series or in parallel.

Assessment of the relationship between water quality and functions of small water reservoirs

Small water reservoirs are one of the principal elements of agricultural landscape in the Central European context. The monitoring of the quality of aquatic environment of selected ponds and small reservoirs (SWR) in areas of southern and central Moravia and the Vysočina Region was carried out in 2013 to 2015.

Quality of sludges and wastes from household and small wastewater treatment plants and their utilization in agriculture management

The aim of this article is to introduce partial sections of the research projects TA02020128 and TA02021032 (Technology Agency of the Czech Republic). These parts of the projects pay attention to the issue of quality of sludge and other wastes produced in wastewater treatment plants (WWTP) using activated sludge process, anaerobic processes (including septics) and extensive (natural) wastewater treatment plants (with horizontal subsurface flow reed-beds), which also include mechanical pre-treatment.
