Impact of the regional climate change on the hydrological regime with regard to extremes
Blahušiaková, Andrea
Investigation of changes in the rainfall-runoff regimes of rivers and its extremes has become more important especially in the context of ongoing and future climate changes. The main aim of this study is to investigate the key factors involved in these changes and thus influence the hydrological regime. Trends and changes in climatic and hydrological variables are detected and the development of flood and drought extremes is assessed. Several methods are used to identify trends and examine their changes; the Mann-Kendall test, linear regression, simple mass curves, and comparative analysis (IHA). Flood extremity is evaluated based on flood activity levels and return period (N-year flood event), frequency and seasonality using the threshold method and culmination day. Extremity, frequency and seasonality of meteorological drought are evaluated by the threshold method, followed by de Martonne Aridity index and Relative precipitation index. Hydrological drought is evaluated based on Base flow index, Low flow index and threshold method. The main variables involved in these analyzes were annual, seasonal and monthly discharge, air temperature, precipitation and snow cover. The database of the base and other calculated variables is compiled for the period from 1931/1961 to 2010/2012. Trends and changes...

Protection of the Earth climate system from the legal point of view
Radošinský, Adrián ; Žákovská, Karolina (advisor) ; Sobotka, Michal (referee)
Climate system protection from the legal point of view The global warming is one of the most serious and acute problem, that is touching all the global society. Growing of the greenhouse gasses is evoking the change of climate system, especially the warming of the Atmosphere and the Earth. In the last 100 years the temperature rises, what cause a lot of problems not just on the environment, but impacts on human health and society. Many of recent scientist studies clearly indicate, that climate changes are a result of human activities. Consequences of the global warming have been observed for several years, included rising global average temperature, rising of the sea level, melting glaciers and severity of extremes such as heat waves, cold waves, storms, floods and droughts. To preclude this consequences, there is necessary a global action with participation of every country. The aim of the diploma thesis is an introduction to the reader create a picture of the functioning of the climate system and its changes, causes and consequences of these changes and clarify the activities to protect, whether it is the activities of international, multinational or the Czech Republic. Finally, I will try to assess the individual activities and measures, including measures of adaptation, or to compare them and...
