Drip irrigation of park area in multifunctional object with rainwater re-use
Kabátek, Stanislav ; Mašíček,, Tomáš (referee) ; Hyánková, Eva (advisor)
The aim of this work is to design an irrigation system of park areas in a multifunctional object using rainwater. The knowledge obtained during the study was used to solve the problem. The solution is an irrigation system consisting of drip irrigation supplemented with a sprinkler irrigation system that uses rainwater for its operation. In the event of excess of rainwater, the water is disposed of by means of infiltration blocks located on the land. The benefit of this work is to show that the return on investment is acceptable in similar cases and, above all, that this investment contributes to responsibility for natural resources.

Treated Waste Water Irrigation
Kohut, Rafael ; Hyánková, Eva (referee) ; Kriška-Dunajský, Michal (advisor)
The thesis deals with the issue of simulation of treated wastewater irrigation by the HYDRUS 2D software. The first part of the thesis is designed as a theoretical research of academic information and knowledge. It aims at introducing the issue of treated wastewater utilization for the purpose of the irrigation. Furthermore it provides basic theoretical information on numeric simulation of the dissolved materials motion and transport in the soil. The last chapter of the theoretical part describes the calibration of the simulation by the HYDRUS 2D software. The second part of the thesis is devoted to the formation of filtration columns placed in the chosen site of the root zone wastewater plant. Within the filtration columns the automatic irrigation was formed and set off. Measuring of humidity in filtration columns was taking place for 81 days as well as the water sampling after the flow through the soil horizons. On the grounds of the measuring results the calibration of numeric simulation was carried out by the HYDRUS 2D software. The last part of the thesis presents the applications through the extending and alternation of the modelled setting. The main aim of the thesis is to calibrate the model and propose a general solution to advancement at realization of irrigation details when using the treated wastewater for the purpose of irrigation.

Study of vineyards irrigation system near near the Chorvátsky Grob village
Jarová, Nicole ; Kameníčková, Ivana (referee) ; Hyánková, Eva (advisor)
The bachelor´s thesis concerns the design of a drip irrigation in the selected location of the vineyard in the village of Chorvátsky Grob. The study focuses on the importance and partition of the irrigation in the chosen location. In the first part of the bachelor thesis, there is a description of the irrigation systems history, the irrigation division, the division of irrigation systems and types of droppers. Subsequently, the description of the micro-irrigation is included. In that I describe the characteristics of a drip irrigation and I evaluate the advantages and disadvantages of the drip irrigation. I describe the types of droppers with the technical conditions and components needed to build the drip irrigation. All factors affecting the irrigation uniformity and factors affecting irrigation water quality are described. Then I present the method of water treatment used in the drip irrigation and the method of the water transport to the irrigated land. In the next chapter, I describe the division of vine types, the composition and the material composition of grapes. At the end I propose the drip irrigation technology in a particular area (the agricultural cooperative farm, vineyard Chorvátsky Grob). All the land-specific data have been processed and the calculation of the water demand for the drip irrigation for this location has been proposed, especially for critical months. Based on data and calculations, I propose to ensure the irrigation for individual sectors. The necessary water intake and minimum operating pressure in the individual sections have been considered. Map data have been processed in the AutoCad programme.

Srovnání efektivity závlahy dřevin pomocí závlahových vaků a klasické zálivky
Omesová, Kristina
The bachelor thesis deals with the comparison of the effectiveness of two types of irrigation used for irrigation of young plantings in cities and in the countryside. Specifically, the irrigation of trees using irrigation bags and irrigation in the form of classic watering for irrigation bowls were compared. The growth and development of trees is not only affected by the method of irrigation, but especially by the environment in which the trees grow. The literature section mentions the impacts of climate change on the environment for tree growth, specific conditions for planting trees in the urban environment, the importance of water for trees, systems and sources of irrigation used in urban greenery. The whole research was carried out on the basis of measuring the length and width of the annual increments and perimeter of the trunk. The measured values were statistically processed and displayed in graphs. The results of the three-year measurement clearly show a higher efficiency of irrigation using irrigation bags at the time of application of irrigation.
