Modeling of water quality in the water supply network
Dukát, Petr ; Rajnochová, Markéta (referee) ; Ručka, Jan (advisor)
This thesis looks at water quality modelling in the water network, focusing on water age. The initial part of the work identifies the factors that lead to an increase in water age in water supply networks. The theoretical part of the work presents the mathematical relationships and logistical steps that software tools apply to simulate water quality indicators in a water supply network. In the practical part of the work, a hydraulic model of a water distribution system with a total length of 302,1 km was constructed. Measurement campaign was carried out to calibrate and verify created hydraulic model. Using this hydraulic model, water age for existing and possible scenarios was simulated. The results of the work have revealed parts of the water supply network containing high water age and are intended to encourage the progressive water distribution systems management philosophy.

Vosáhlo, Jan ; Vybíralová, Pavla (referee) ; Biela, Renata (advisor)
The theme of this thesis is " Evaluation of water quality in water treatment plant Mokošín". The source of water supply are 4 artesian wells. The paper first describes the supply area and water treatment plant with individua water treatment technologies. In the practical section there is the specification of contaminating elements required to be separated at the water treatment plant. Since it is an underground source of water, there is an increased amount of iron and manganese. Increased attention is given to arsenic, which occurs in two water sources in recent years. There are also offered the possibilities of removing arsenic at water treatment plant and two filter materials tested in the laboratory. Monitoring of water quality takes place always in resources and after treatment in the time period of five years, the arsenic values are reported for ten years.

Software for simulation of water treatment and water distribution processes
Pavliš, Jan ; Malaník,, Stanislav (referee) ; Kučera, Tomáš (advisor)
This document aims on presentation of software focused on mathematic modelling in water treatment and water distrinbution. It consists of a list and descriptions of a number of programs which use static or long-term analysis in examining hydraulics in water distribution systems and also examine water quality parameters. There are other programs also included in this thesis that solve different types of analysis or water engineering structures. Then we can find elaborate descriptions of programs ARTS and Epanet and example analysis of both too. ARTS simulated waterhammer process and Epanet analysed water age through the water distribution system of a small village. This thesis brings basic overview of available programs designated for engineers of water treatment and distribution systems and is also the first step for my future Master´s thesis in which I would like to deeply focus on one of the programs.

EXTENDED METHODOLOGY FOR WATER RESOURCES AND WATER-RELATED ENERGY ASSESSMENT ADDRESSING WATER QUALITY
JIA, Xuexiu ; Ditl,, Pavel (referee) ; Dr hab. inż. Paweł Ocłoń, prof. PK (referee) ; Dr. Aoife M. Foley (referee) ; Varbanov, Petar Sabev (advisor)
Problémy s vodou, zejména její nedostatek a znečištění, ovlivňují každodenní lidský život a hospodářský vývoj. Globální změny klimatu zvyšují pravděpodobnost a četnost extrémních událostí jako jsou sucho a záplavy. Rostoucí problémy s nepravidelnou dostupností a znečištěním vody vyžadují pokročilejší metodiky hodnocení vodních zdrojů, které povedou k efektivnímu využití a hospodaření s vodou. Tato práce se zabývá rozšířenými metodikami pro hodnocení vody z pohledu její kvality a kvantity a pro hodnocení spotřeby energie a produkce emisí souvisejících s vodou. Tři hlavní metodiky jsou navrženy na základě konceptu vodní stopy (Water Footprint) a pinch analýzy vody (Water Pinch Analysis) pro posouzení kvantitativních a kvalitativních hledisek využití a spotřeby vody. Použití těchto metod je rovněž demonstrováno pomocí numerických a empirických případových studií zaměřených na hodnocení a optimalizaci využití regionálních a průmyslových vodních zdrojůDále jsou diskutovány souvislosti mezi vodou a energií (Water-Energy Nexus) za účelem analýzy problémů týkající se vody z širší perspektivy. Z pohledu vody a vodních zdrojů je provedeno počáteční zhodnocení energetické náročnosti a produkce emisí skleníkových plynů v problematice odsolování mořské vody. Výsledky prezentované v této práci navazují na současné metodiky hodnocení vodních zdrojů. Stopa dostupnosti vody (Water Availability Footprint) byla navržena pro zohlednění dopadu degradace kvality vody ve stávajících postupech pro posuzování nedostatku vody, ve kterých nebyla dříve řešena. Druhým přínosem této práce je návrh konceptu kvantitativní-kvalitativní vodní stopy (Quantitative-Qualitative Water Footprint - QQWFP), ve kterém je definována vodní stopa z pohledu nákladů a následně je stanovena v souvislosti s celkovými náklady na spotřebu vody a odstraňování kontaminantů, které se do vody dostávají v průběhu jejího využití. Vodní stopa založená na nákladech poskytuje výsledky, které jsou intuitivnější jak pro management vodních zdrojů tak i pro veřejnost. Tento přístup umožňuje lépe kontrolovat a řídit průmyslové a regionální využívání a správu vody. Třetím přínosem této práce je rozšíření pinch analýzy nedostatku vody (Water Scarcity Pinch Analysis - WSPA), ve které je aplikována pinch analýzy vody na makroúrovni se zaměřením na regionální hodnocení a optimalizaci zdrojů a využívání vody. Všechny tři navržené metody jsou zaměřeny na stanovení dopadů využití vody z hlediska jejího množství a kvality, analýzy QQWFP a WSPA také pokrývají dopady vícečetných kontaminantů. Kromě hledání řešení se tato práce také pokouší naznačit potenciální směry pro budoucí výzkum v dané oblasti. Mezi významná potenciální témata k diskuzi patří 1) pokročilejší metoda kvantifikace vlivu více kontaminantů a 2) implementace a analýza ekonomické proveditelnosti přístupů WSPA a QQWFP s lokalizovanými daty s cílem nalézt přizpůsobené řešení pro optimální využití regionální a průmyslové vody.

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.
