Hydroecological monitoring and revitalisation of small water course
Komendová, Denisa ; Hubačíková,, Věra (referee) ; Hyánková, Eva (advisor)
This thesis deals with the hydroecological monitoring and river restoration of the Syrovinka watercourse in Hodonín district. In the framework of the hydroecological monitoring a river hydromorphological assessment was conducted as a part of assessing the ecological status of watercourse, to meet the requirement of the Water Framework Directive. Hydroecological monitoring was conducted using methodology HEM 2014, which is accepted as a national standard by the Ministry of Environment of the Czech Republic. Problematic reaches of watercourse were determined and for the selected reach a river restoration measures have been designed. Subsequently, an efficiency of river restoration was evaluated. The main benefits of designed river restoration are the restoration of ecological function and the support of natural water retention in floodplain.
Specifics of the hydromorphological monitoring on small water courses and its improvement
Beneš, Jakub ; Kriška-Dunajský, Michal (referee) ; Hyánková, Eva (advisor)
This thesis deals with hydroecological monitoring of watercourses. The HEM – Hydroecological monitoring is part of evaluation of status of watercourses, which is a requirement of the European Water Framework Directive. The content of this thesis is firstly to find out the status monitoring of hydromorphological quality of watercourses in the Czech Republic and a subsequent survey of methodology HEM. The aim of this thesis is comparison with the older methodologies and ways to improve the practical implementation of monitoring on smaller waterways. Measurement and knowledge will be applied to Troubsko creek.
Hydromorphological monitoring of small water course and its evaultaion
Beneš, Jakub ; Kriška-Dunajský, Michal (referee) ; Hyánková, Eva (advisor)
This thesis is dealing with the hydroecological monitoring watercourses. The HEM – Hydroecological monitoring is part of the assessment of the status of watercourses, whitch is a requirement of the European Water Framework Directive. The content of this thesis is to evaluate a small stream throught two chosen methods (HEM and Bavarian method). The methods is compare with each other and with the state of the stream in 2008. The aim of the study is to compare the suitability of methods and their application.
Evaluation of the development of ecological potential in selected canyon-shaped reservoirs with respect to their fish communities.
Říha, Milan ; Blabolil, Petr ; Soukalová, Kateřina ; Peterka, Jiří
The report assesses the development of the ecological quality index with respect to a fish community in selected reservoirs. The assessment was carried out for reservoirs where fish stocking was sampled in different years and thus it was possible to assess the temporal evolution of this index. The report describes the calculation of the index, the trends in the index for each reservoir and the cause of changes in the index.
Princip nákladové přiměřenosti v právních předpisech EU v oblasti životního prostředí: ponaučení z implementace ochrany vod a ovzduší
Brabec, Jan ; Jílková, Jiřina (advisor) ; Knápek, Jaroslav (referee) ; Slavíková, Lenka (referee)
Environmental legislation in the European Union recognizes the principle of proportionality as a tool that helps identify cases that require spending of disproportionate resources to achieve environmental targets. If economic costs of achieving a certain target are significantly higher than associated benefits, an exemption may be granted to prevent wasting resources on measures with only a negligible effect on the environment. The principle is well established in water protection by means of the Water Framework Directive (2000/60/EC) and in air protection through the Industrial Emissions Directive (2010/75/EU). In theory, such setting should ensure more efficient and robust water and air protection. However, with no unified methodology and a high level of discretion given to individual member states, the process of assessing proportionality has become very heterogenous. As a result, methodologies used across Europe often differ from each other significantly, possibly distorting the original idea of equal treatment of European water bodies and sources of air pollution. The goal of this thesis is to determine whether the use of the proportionality principle in water and air protection contributes to more efficient environmental protection in the EU and whether the principle is used consistently in...

Assessment of Czech water-bodies ecological potential based on fish community
BLABOLIL, Petr
Ongoing environmental changes and increasing pressure on freshwater habitat require that we understand the ecological quality of freshwater ecosystems across a wide range of habitat types. This Ph.D. thesis addresses the utility of fish as ecological indicators in heterogeneous reservoir ecosystems. In the first section, I develop suitable indices and calculate ecological potential in two case studies, one using common fish guilds and traits at a large continental scale and another using species-specific indicators for a country-specific dataset. In the second section, I compare the assessment of fish communities across a large geographical region and identify anthropogenic stressors with the highest impact on fish communities. In the third section, I discuss the issue of optimal gillnet sampling design for reliable fish indicator values to increase the utility of assessment methodologies and to reduce sampling effort and fish mortality required to obtain reliable data. In the fourth section, I compare estimates of fish recruitment based on different sampling methods and develop a novel statistical approach to analyse factors affecting fish recruitment. This work provides an initial step towards the improvement of ecological quality of freshwater reservoirs.

Jak čelit nejistotě při rozhodování o odstranění fosforu ve vodohospodářství
Brabec, Jan ; Vojáček, Ondřej (advisor) ; Zajíček, Miroslav (referee)
Implementation of EU Water Framework Directive has led to an increased demand for cost-benefit analysis in water management. The directive introduces a good status, which is required on all water bodies by 2027. Excessive phosphorus inflows are one of the main reasons for not meeting the criteria in the Czech Republic. If achieving of the good status is not cost-proportionate, exemption can be applied. Many different methodologies were created across different states, including Czech official methodology by Slavíková et al. (2015). However, this methodology does not deal with uncertainty of measures effectiveness. This thesis describes how to implement the uncertainty into calculations using Bayesian networks. A case study of Stanovice water reservoir demonstrates the approach practically. Results of the Bayesian network show, that selected measures with available data eliminate desired amount of phosphorus in 70% of all cases. This reduction is most likely sufficient, because it holds for the upper estimate of required abatement (60 to 200 kg). Based on comparison of benefits and costs, it seems net benefits are generated by implementing suggested measures. Therefore, policy recommendation is to implement the selected measures.
