Legal regulation of watersourse protection
Altmann, Martin ; Sobotka, Michal (advisor) ; Derlich, Stanislav (referee)
Thesis title: Legal regulation of watercourse protection Abstract Watercourses are the most important form of surface water occurrence in the Czech Republic, and therefore their condition also significantly affects the overall state of all our aquatic ecosystems. Despite of it, the ecological and chemical status of watercourses is still not satisfying. This fact requires an increase in the efficiency and complexity of their legal protection, which is the subject of this thesis. The aim of the first part of this thesis is to describe the national legal regulation of watercourses protection in the context of European and international law. At present, national and international legislation is significantly influenced by European legislation provided by the Water Framework Directive. The first part pays attention to the instruments of national legislation, that are relevant to the second part of the work. The first aim of the second part of this thesis is to analyse the basic measures proposed in the two selected sub-basins in order to achieve the objectives of the Water Framework Directive, particularly the good water status. Following this analysis, the second aim is to find out what specific instruments the current legislation provides for the realization of the proposed measures and whether these...

Long-term trends in water quality of pond Světin relation to fish management
Altmann, Martin ; Duras, Jindřich (advisor) ; Vrba, Jaroslav (referee)
Fishpond ecosystems provide many other services besides fish production. One of them is the retention of nutrients and thus ability to change the quality of the through flowing water, thereby ability to influence the overall quality of surface waters. In the case of the fishpond Svět in Třeboň it is also recreation, as the pond is an integral part of the tourism of the town. Water quality in the fishpond and its retention capacity of phosphorus is connected with the fish management and the inflow of nutrients from the catchment basis, especially within a cascade of ponds and densely populated or agricultural regions. This thesis evaluates seasonal (2013, 2015) and long term (2007-2015) trend of water quality of pond Svět in Třeboň in relation to fish management. Furthermore, mass balance was calculated for 2015 and estimated for 2013. The years 2015 and 2013 (the first years of production cycle) varied considerably in amount of annual rainfall. The year 2015 was extremely dry and 2013 very aqueous. Different hydrological conditions caused different seasonal courses in hydrochemistry parameters and its concentrations. The water quality of fishpond Svět is in the most of parameters better in comparison with other production fishponds in the Třeboň region and also the intensity of fish management is...

Assessment of water quality and physical river habitat chages in the interaction on macroinvertebrates.
Altmann, Martin ; Matoušková, Milada (advisor) ; Benešová, Libuše (referee)
Streams are an important part of the most ecosystems, they help them to maintain their stability and function. They should therefore be the subject of study and especially protection. For their monitoring and assessment of ecological status is increasingly used biomonitoring of benthic fauna, which well reflects the biotic and abiotic conditions in physical habitats of streams. These abiotic conditions of physical habitats which are shaped by physical and chemical factors are the subject of literature search part of this work. The second part is about the research in experimental catchments of Zbytinský brook and Tetřívčí brook, tributaries of headwater Blanice river which springs in the foothills of the Šumava mountain range. The research took place on 5 sampling sites which are different in hydromorphological parameters and rate of human activities impact. There was assessed water quality following the previous research and its relationship with discharge conditions. In the case of Tetřívčí brook, there was also assessed physical habitat and macrozoobenthic community. Zbytinský brook catchment was in the past significantly affected by agricultural activities. The main reach, which flows through Zbytiny village with 300 inhabitants, and its tributaries were meliorated. The only one tributary...
