Jakost vody vybraných rybníků v povodí toku Vydrica
Krajči, Filip
The diploma thesis is focused on the assessment of water quality in two successive ponds located on the Vydrica stream in the Malé Karpaty mountains. The analysis and subsequent assessment of water quality is based on field monitoring associated with the collection of samples and their subsequent analysis in the laboratory. The literary research deals with the assessment of water quality, the distribution of water, the distribution of protected landscape areas, but also the methods of management of ponds and the susitability of given ponds from the point of view of fish breeding. The literature review also contains a description of field monitoring indicators and laboratory determinations. The methodological part describes the principles of establishing field research and analysis of monitored water samples in the laboratory and the characteristics of sampling sites. The results obtained by field measurements and subsequent laboratory analysis were evaluated based on STN 75 7221 and Government Regulation No. 269/2010 Coll. After the evaluation, it was found that the water achieved the worst results, especially in the field of indicators reflecting organic pollution (BOD5, CHSKcr). Also, the content of elements such as total nitrogen and total phosphorus reached levels exceeding the limits of the worst class. These facts can further help in the management of the designated areas or in revitalization works in the vicinity, which are planned in the near future.

Monitoring jakosti vody vybraného toku
Zálešák, Petr
The bachelor thesis focuses on the evaluation of water quality in the Velička River. The Velička is located in the Hodonín district in southern Moravia. Its total length is 40.2 km. Its source is on the western slope of Velká Javořina and flows into the Morava River near Strážnice. The water flow was monitored in eight profiles at two-month intervals for one year. The monitoring had two phases. The first phase consisted of taking a water sample and measuring some of the water quality parameters in the field using an instrument kit from Hach Company. These were indicators of pH, conductivity, oxygen content, and water temperature. The second phase was carried out in a laboratory by measuring the quality parameters from the water samples using a spectrophotometer. The concentrations of total phosphorus, sulphates, nitrate nitrogen, and chlorides were monitored. The quality of the water in the river was evaluated according to the ČSN 75 7221 standard and government regulation No. 401/2015 Coll. Total phosphorus was evaluated as the most unfavorable qualitative parameter.

Vyhodnocení účinnosti čistírny odpadních vod Hodonín
Chocholáčková, Zuzana
The diploma thesis deals with wastewater and rating of efficiency of the wastewater treatment plant (WTP) Hodonín, which cleans communal and industrial wastewaters. Chapter of the literary research describes law regulations dealing with wastewaters, furthermore deals with water pollution, wastewater and wastewater treatment plant technological equipment. Next chapter contains characteristics interest area, its natural and economic conditions and traffic description in WTP Hodonín. I calculated efficiency for selected indexes for the period since 2003 to 2018 from the provided database from company Vodovody a kanalizace Hodonín, a.s.. This values of efficiency and values of concentration of these indexes were compared with emission standards stated in relevant government orders and processed to charts. Average values of efficiency in the observed period were always beyond required limits. Due to my own monitoring, were stated values of biochemical oxygen demand, total nitrogen, total phosphorus, nitrate nitrogen, ammoniacal nitrogen and orthophosphates by spectrophotometry. I calculated efficiency of cleaning from these values and compared them with relevant limits. The results showed that efficiency of cleaning in WTP Hodonín is about 15% higher than it should be due to legislative.

Zhodnocení stavu povodí Kovalovického potoka
Křížová, Petra
This bachelor thesis The evaluation of the river basin condition of the Kovalovický potok deals with monitoring of concrete water quality indicators. The following parameters were observed: dissolved oxygen, conductivity, pH, temperature, nitrate nitrogen, total phosphorus, orthophosphates and chemical oxygen demand. The monitoring took place between the March 2017 and February 2018 on eight profiles, where the water was taken. The theoretical part is focused on general information about water and its basic sorting, surface water quality and its pollution and water erosion issues. Then, there are selected indicators of surface water quality and their characteristics, as well as chosen legislation dealing with surface water pollution. The practical part is concentrated on the river basin characteristic, description of the sampling points and description of the field and laboratory work. An important part is the results of the measurement and discussion in which these results are compared with ČSN 75 7221 and NV 401/2015 Sb. The results show that the largest pollution is caused by sewage that is illegally discharged into the watercourse.

Znečištění Dunaje, dopady na Černé moře
Hudcová, Aneta
The bachelor thesis deals with the state of the Danube River in terms of water pollution. The Danube is the second longest river in Europe and flows through ten states. Its major tributaries rise in several other countries. Each state pollutes the Danube and its basin with different sources and in different intensity. This is due to many factors but one of the most significant is economic development. The influence of anthropogenic activity on the river is highly reflected in the quality of the aquatic environment which also has a negative impact on the Black Sea. The high nitrogen and phosphorus content causes eutrophication which disrupts the entire Danube water ecosystem. Subsequently, the Black Sea ecosystem is also disturbed which is also facing this issue. The main aim of this thesis was to analyze the issue on the basis of literature in the first part and the second part focuses on the pollution of the river Danube in different ranges of years. It also sets out states that have the greatest share of this pollution. After comparing values that were evaluated from water abstraction from all the states, the state of the Danube is presented in percentage at the end. The pollution status of the Danube has improved in most cases. High pollution is mainly caused by the lower and middle Danube states.

KALVODOVÁ, Vanda
The result of the proposed diploma thesis on "Revitalization variants assessment of the Maříž chetau park and proposal of alternative solution of park revitalization concept" is a "own variant" and evaluation of the alternative solutions for the revitalization of the Maříž chateau park. The first variant is named "non-intervention variant", which describes a status of the chateau park in year 2009, before making any intervention for revitalization. The second variant is a "design variant", that planners worked out for the owner of the park. The last variant is the "own variant" processed by the author of this diploma thesis. Each variant is evaluated in cultural-historical, ecological, economical, and social and educational terms through SWOT analysis. The diploma thesis found that in a village of Maříž there is already partly revitalization of the greenery. The main problem is the surface water pollution by waste water at present. The waste water problem is processed within of alternative solution of park revitalization koncept.
