The application of the distributed hydrological model brings the benefits of assessment of the spatially distributed quantities which are hard to measure in the field over a larger area, e.g. evapotranspiration. The Malše River basin has been chosen for the evaluation of evapotranspiration simulation by the distributed hydrological model, SWIM (Soil and Water Integrated Model). The primary interest in this analysis was to assess the ability of the hydrological model to simulate the actual evapotranspiration on larger scales and to evaluate its dependence on the landscape characteristics such as the vegetation cover, soil type, and average precipitation amount during the simulation. Annual actual evapotranspiration in each hydrotope was evaluated in the simulation period of 1985–1998. Because of the lack of the data observed (evapotranspiration), the model was calibrated on the discharge time series. The credibility was quantified using Nash Sutcliffe efficiency which was more than 0.7. The main trends of the simulated actual evapotranspiration were evaluated and assessed as satisfactory. The differences in the soil types did not seem significant for the evapotranspiration variation, the monthly average values among soil types differing by ± 10% except histosol. On the other hand the differences in the land-use categories strongly influenced the amount of evapotranspiration (–30; +50%). It appears that the model SWIM overestimates the actual evapotranspiration in the spring and, on the other hand, underestimates that in the autumn according to the comparison with the only data available in the entire Climate Atlas of the Czech Republic.

The contribution “Anti-state Crimes in Modern Codifications” deals with the topic of anti-state crimes during centuries. Firstly, legal concepts in the pre-state period are mentioned. Then the attention is paid on the evolution of this institute in the Euro-Atlantic area. From this point of view, there are mentioned mainly regulations from England (1351), France (1810), Germany (1871) and Soviet Union (1958) which could be remarked as the most important for the development of other countries. On the other hand, it also reminds the development of codifications in Czechoslovakia, the Czech Republic and Slovakia, which were affected by the Austro-Hungarian legislations as well as German and Soviet approaches. The Czech current arrangement generally does not depart from the other European samples, but it cannot be omitted that in the Czech Republic it is distinguished the penal concept of the high treason (Landesverrat, vlastizrada) from the constitutional concept (Hochverrat, velezrada) which is dedicated to the presidential anti-state activities. The contribution also indicates that the concept of anti-state crimes in countries has not been unified and it has been varying according to various experiences and attitudes.

The aim of the study was to analyse the formation of pig belly in relation to sex. The analysis included in total 193 slaughter pigs of final hybrids currently used in the Czech Republic. The pigs were slaughtered at the age of 166–175 days. The VIA method according to the methodology of Schwerdtfeger et al. (1993) was used to evaluate the formation of belly and to estimate the percentage of lean meat. The calculation of the lean meat and its proportion in the belly was based on the equation according to Čítek (2002). The belly in total as well as the EU belly in barrows reached the weight of 7.85 kg and 4.35 kg, respectively, and in gilts 7.66 kg and 4.12 kg, respectively. With almost the same weight of dressed carcasses, the belly in barrows accounted for a higher proportion, i.e. 9.96% compared to 9.56% in gilts. In terms of percentage the gilts had a statistically highly significantly higher proportion of meat in the EU belly, namely by 3.32% compared to barrows. At all points of measurement the higher total area of the belly section was found in barrows compared to gilts. A comparison of the percentage proportion of lean meat area in the total belly area at individual points of measurement indicated statistically significantly higher values in gilts than in barrows. It was confirmed that in the section area from point 1 to point 3 the deposition of fat in barrows was higher with the values of the meat area ranging from 58.15% to 56.09%. On the other hand, in gilts the differences between individual sections were very small: 61.25%, 61.99% and 61.49%.

Abstract This work examines the main features of the flash flood regime in Central Europe as revealed by an analysis of flash floods that have occurred in Slovakia. The work is organized into the following two parts: The first part focuses on estimating the rainfall-runoff relationships for 3 major flash flood events, which were among the most severe events since 1998 and caused a loss of lives and a large amount of damage. The selected flash floods occurred on the 20th of July, 1998, in the Malá Svinka and Dubovický Creek basins; the 24th of July, 2001, at Štrbský Creek; and the 19th of June, 2004, at Turniansky Creek. The analysis aims to assess the flash flood peaks and rainfall-runoff properties by combining post-flood surveys and the application of hydrological and hydraulic post-event analyses. Next, a spatially-distributed hydrological model based on the availability of the raster information of the landscape’s topography, soil and vegetation properties, and rainfall data was used to simulate the runoff. The results from the application of the distributed hydrological model were used to analyse the consistency of the surveyed peak discharges with respect to the estimated rainfall properties and drainage basins. In the second part these data were combined with observations from flash flood events which were observed during the last 100 years and are focused on an analysis of the relationship between the flood peaks and the catchment area. The envelope curve was shown to exhibit a more pronounced decrease with the catchment size with respect to other flash flood relationships found in the Mediterranean region. The differences between the two relationships mainly reflect changes in the coverage of the storm sizes and hydrological characteristics between the two regions.

AbstractThe article examines the section of officials in the central administration who belong to the ministerial staff of the Czech Republic. It examines those persons engaged in the creation of analyses, strategies, and management activities. The study is based on original research conducted by the ministries of the Czech Republic in 2013 (N = 1351). The article seeks to discover what the make-up of this group is in terms of gender, age, and education levels at the chosen ministries, as well as to report on the types of experiences the group has had. The analysis shows that ministerial officials are in fact a gender-balanced group of employees, predominately university-educated. The overall median age of employees in all ministries is 42 years. On the other hand, there are certain inter-ministerial differences, as explained in detail in this paper. Based on results of the empirical research, conclusions have been drawn that may also serve as an inspiration for similar investigations in other countries of Central and Eastern Europe that address similar issues as found in the Czech Republic.

Abstract. The impact of projected climate change on the long-term hydrological balance and seasonal variability in the federal German state of Thuringia was assessed and analysed. For this study projected climate data for the scenarios A2 and B1 were used in conjunction with a conceptual hydrological model. The downscaled climate data are based on outputs of the general circulation model ECHAM5 and provide synthetic climate time series for a large number of precipitation and climate stations in Germany for the time period of 1971 to 2100. These data were used to compute the spatially distributed hydrological quantities, i.e. precipitation, actual evapotranspiration and runoff generation with a conceptual hydrological model. This paper discusses briefly the statistical downscaling method and its validation in Thuringia and includes an overview of the hydrological model. The achieved results show that the projected climate conditions in Thuringia follow the general European climate trends – increased temperature, wetter winters, drier summers. But, in terms of the spatial distribution and interannual variability regional differences occur. The analysis showed that the general increase of the winter precipitation is more distinct in the mid-mountain region and less pronounced in the lowland whereas the decrease of summer precipitation is higher in the lowland and less distinct in the mid-mountains. The actual evapotranspiration showed a statewide increase due to higher temperatures which is largest in the summer period. The resulting runoff generation in winter was found to increase in the mid-mountains and to slightly decrease in the lowland region. In summer and fall a decrease in runoff generation was estimated for the entire area due to lower precipitation and higher evapotranspiration rates. These spatially differentiated results emphasize the need of high resolution climate input data and distributed modelling for regional impact analyses.
