Hodnocení zdravotního stavu výsadeb dřevin rostoucích mimo les s různou úrovní následné péče v Moravskoslezském kraji
Gregořicová, Anna
This bachelor thesis deals with the influence of the quality of aftercare after planting on the vitality, health and prospects of trees. The evaluation was carried out at five localities around the city of Opava in the Moravian-Silesian region. A total of 871 individuals were monitored. The rating was carried out using a modified and extended methodology based on the Arboricultural Standard - Tree Condition Assessment SPPK A01 001:2018 from the AOPK ČR. The effect of the quality of post-planting care on the subsequent perspective of the planted trees was confirmed. The assessment also included the identification of the most common causes of dieback or reduction of perspective, including the identification of other influences affecting plantations.

Environmental aspects of wastewater treatment and reuse in nature based technologies
Šereš, Michal
In recent years, the issue of appropriate and efficient approaches to wastewater management and its potential reuse has become increasingly important in view of the geographical conditions of Central Europe, where, until recently, the problems associated with climate change and drought may not have seemed so pressing at first sight. Increasingly, so-called nature-based water management solutions, which help to both clean the water and retain it in the landscape, are being proposed. In drier, especially arid areas, this topic has been under discussion for many years and several examples of larger-scale applications are available. In the Czech Republic, on the other hand, mainly pilot applications only have been considered to date. However, the potential of nature-based solutions such as constructed wetlands, denitrification bioreactors, artificial wetlands and so-called reed bed units, is considerable. The advantages lie mainly in the robustness of these systems and their ability to mimic and intensify the natural water purification processes that occur in nature. They can be applied to waters contaminated with common fecal pollution or with higher nutrient content, as well as to waters contaminated with various types of micropollutants such as pharmaceuticals, hormonally-active substances and...

The mechanisms and efficiency of uptake of selected micropollutants by crops irrigated with reclaimed wastewater
Šrédlová, Kamila ; Semerád, Jaroslav ; Šereš, M. ; Mrvová, M. ; Rozkošný, M. ; Cajthaml, Tomáš
Water scarcity and the quality of fresh water are important global issues, which relate to all areas of human activity. One of the possible ways of reducing water consumption in agriculture is using treated (recycled) wastewater for irrigation. However, when applying recycled wastewater or biosolids to crops, it is necessary to monitor the content of micropollutants. The Summary research report describes the mechanisms of uptake of selected micropollutants (perfluorinated alkyl compounds and pharmaceuticals) by crops during automated irrigation with recycled wastewater. A detailed literature review complemented by experimental data describes micropollutant bioaccumulation in the fruits of several plants, which represent an exposure pathway for humans. Furthermore, the risk of human intake of micropollutants from crops potentially contaminated when grown using this technology is outlined

Irrigation systems in the past and nowadays
Slinčák, Andrej ; Fialová, Simona (referee) ; Štigler, Jaroslav (advisor)
The bachelor thesis is focused on general overview of problematics of irrigation systems for large agricultural fields, as well as micro-rrigations for gardens. It includes pros and cons of every system and elucidate appropriate aplication of irrigation to certain conditions. Thesis describes elements of irrigation system and conditions for its proper functioning. In the first part is described brief history of irrigation systems, afterwards its division by use and the way they work. I also added short introduction to gravitation (surface) irrigation. It is these techniques, which are used in developing countries with sufficient water resources. The second part is a description of a specific irrigation system from my neighborhood. I have chosen our automatic irrigation system from firm TORO, which is used for lawn irrigation.

Use of buildings rainwater for irrigation and soaking ind the Moravské Křižánky village
Hubený, Michal ; Kameníčková, Ivana (referee) ; Hyánková, Eva (advisor)
The bachelor thesis deals with the issue and utilisation of rainwater. The thesis is divided into two parts - theoretical and practical. Theoretical part consists of general rainwater distribution, the formation of individual rainfall - its composition, quality, surface run-off, individual possibilities of water purification, accumulation and infiltration. The ways of using rainwater in households and gardens are also described in thesis. The practical part deals with the use of rainwater around a family house in the specific location. The area is located in the village called Moravske Krizanky in Vysočina region. In conclusion, a complete solution for rainwater accumulation, irrigation and infiltration was developed.

The effect of irrigation with treated wastewater on the development of soil hydrophobicity
Fojtová, Zuzana ; Innemanová, Petra (advisor) ; Šereš, Michal (referee)
In this work I have dealt with the influence of irrigation with treated wastewater on the development of soil hydrophobicity. In the theoretical part I deal with the influence of using treated wastewater on the development of hydrophobicity in soils irrigated in such manner, the methods used for measurement and in general the benefits and risks of application of treated wastewater to soil. In the practical part, I focused on measuring hydrophobicity using the Water Drop Penetration Time (WDPT) method. Soil samples originated from the Hostětín, where a long-term irrigation test with treated wastewater is underway. For the purpose of testing the WDPT method, soil samples taken at the beginning of the experiment (in 2018) were used, as well as long-term irrigated samples with treated wastewater from the constructed wetland under laboratory conditions. As a control served irrigation with well water and part of the samples from both variants was additionally irrigated with rainwater, which simulated the amount of precipitation that fell on average in the Zlín Region during the experiment. The water used for this experiment came from a constructed wetland close to the Perlová voda complex near Kostelec nad Ohří in the Ústí Region. The samples were irrigated for one year. The method was further tested on...

Automated measuring system for irrigating plants with IoT connectivity
Lahoda, Vladimír ; Polák, Ladislav (referee) ; Kufa, Jan (advisor)
This bachelor thesis deals with IoT networks and considers their use as part of embedded devices. The purpose of this device is to control the flower bed or garden based by data from sensors monitoring the environment. The device not only controls the irrigation operation itself, but also sends all traffic data over the IoT LoRa network. Thus, the device also functions as a weather station, as all data are sent to a second device that acts as a receiver. This receiver displays the data and also sends them to the Internet, where the data are publicly available. The module for sending and measuring data is mounted on its own PCB and is covered in a waterproof cover, so they can be operated outdoors. There is an integrated battery, which is a backup of savings in case of power failure. The battery is designed to back up power for 25 days.
