The diploma thesis "Study of runoff conditions of selected river basin using hydrological modeling" deals with analysis of runoff conditions and retention abilities of the Kašnice stream basin in the Břeclav district. The theoretical part deals with the literature review of the issue and the characteristics of the selected drainage area. Obtained information about surface cover types, hydrologic soil groups and CN curves numbers were processed in ArcGIS. The outputs were then used as input for the DesQ-MAXQ hydrological model. The resulting values of specific flow, time of concentration, potential retention, water retention and direct runoff volumes are presented in the form of attached map outputs. The result of the work is the evaluation of runoff conditions of the given 4th order river basin.

This Diploma Thesis is focused on the analysis of the Ketkovice cadastral area in terms of runoff and erosion conditions. The QGIS software was chosen for the analysis. For this reason, instructions for this software are prepared, focusing on runoff and erosion conditions, as an appendix to the Diploma Thesis. Other software programs used are USLE2D and DesQ-MaxQ. The first part deals with the analysis of the area of interest. The second part deals with the problem itself, at first the methods used to determine runoff and erosion conditions are introduced, then anti-erosion measures, at the end of this part the software programs used are briefly described. The last third part is devoted at first to the evaluation of runoff and erosion conditions before the design of the measure, then to the design of the measure itself, finally to the evaluation after the design of the measure. In case of erosion conditions, two variants of calculating long-term soil loss are considered before and after the proposed measures. In the first variant, a constant value of the factor R=40 MJ.ha.cm.h is considered in the Universal Soil Loss Equation and in the second variant this value is increased with respect to the climate change.

Cyano-bridged mixed valence compounds have been known since 1704, but a lot of interest in the bi- and tri-nuclear species has emerged only more recently. The growing interest in these complexes reflects their promise as useful applications in electrochromism, molecular magnetism, and molecular electronics. These properties are activated by the excitation of their metal-to-metal charge transfer (MMCT) transition. We have studied aqueous solutions of the FeHEDTA/Fe(CN)64- system that form intensely colored solutions that absorb strongly in the Vis/NIR region. Typically 1:1 dimeric and 2:1 trimeric complexes are formed. We have used optical spectroscopy and electrochemistry to provide information on reorganizational parameters, electronic coupling between metal centers, molar absorptivities, equilibrium constants, and delocalization factors and have compared results obtained for the binuclear and trinuclear species to results of similar systems either previously studied in our lab or found in the literature.

Annotation Erosion is a chronic problem in both agricultural and nonagricultural land. Its has an inconsiderable effect on overall stability of landscape. In the case of farming management on agricultural soils the risk of erosive processes increases severalfold. In foothill and mountain areas with dominance of slopes and hills the soil loss during higher maximum 24hrs N-rainfalls can reach up to several tons per hectare. This work deals with the evaluation of soil erosion vulnerability in selected catchment {--} Ostrice catchment {--} in the Lipno reservoir area. The CN method was used for calculations and following evaluation of soil loss.

The aim of this thesis is to assess and evaluate the erosion phenomena at the model catchment of Malče Budský stream. This site is located on the cadastral areas Besednice, Soběnov and Malče. This survey was conducted in aspects of pedology, hydrogeology and climate. Further evaluations were rain amount for the nearest meteorological station, which is located in Soběnov. To evaluate and calculate erosion parameters for a given locality the methods of universal soil loss equation by Wishmeier and Smith and modified universal soil loss equation by Williams and Berndt have been used. The CN method was used for calculations and following evaluation of soil loss. The result of this thesis is designing, generalization and refinement of individual factors in solved area.

The aim of the thesis is to set a hydrology model based on existed methodology DesQ-MaxQ, which comes from "Designing flows from a very small catchments" established in 1989. The model is able to set a nearest meteorology station and his 24-hours rainfall depths for periods of repetition 2,5,10,20,50 and 100 years. Substitute rainfall depths are set by "reduction of 24-hours rainfall depths" methodology. According to hydraulic and hydrology conditions of catchment, duration of the critical rains for each period of repetition are set also peak flow rates and total runoffs from the catchment. Application can work in two modes - "one slope" and "two slopes". The second option also includes calculation of design duration for the model catchment and superposition of hydrograph. Application RainRunoff was develop in C# programming language with graphic user interface and option to exports hydrographs.

The question of ‘the Pictish language’ has been discussed for over four hundred years, and for well over two centuries it has been the subject of ceaseless and often heated debate. The main disagreement focusing on its linguistic categorisation – whether it was Celtic, Germanic (using modern terminology) or whether it belonged to some more exotic language group such as Basque. If it was Celtic then was it Brittonic or Goidelic? The answer to such questions was of some importance in ascertaining to whom the Scottish past belonged. Was it to immigrant Irish, conquering Germanic peoples or native Britons? The twentieth century saw the normalising of the view that it was closely related to Brittonic with some erudite scholars maintaining that another, non-Celtic language, was also spoken in Pictland. The debate subsequently shifted to focusing on just how close was the relationship between Pictish and Neo-Brittonic. Was Pictish simply a northerly dialect variant of the latter or was it indeed a more distinct and perhaps conservative form, evolving independently in an area outwith Roman power and linguistic influence? Recently, as the field of Pictish studies was subjected to both linguistic and historical scrutiny, discussions have become significantly more sophisticated, but the core question remains, as to whether Pictish distinctiveness merits the label ‘dialect’ or ‘language’, as the Venerable Bede himself stated. This thesis will investigate this core issue by providing an overview of previous thinking and scrutinising the evidence for early divergence. It is intended as groundwork for much needed further studies into this field.

Doctor of Philosophy / Department of Biological & Agricultural Engineering / Stacy L. Hutchinson / The Soil Conservation Service-Curve Number (SCS-CN) method is widely used to estimate direct runoff from rainfall events; however, the method does not account for the dynamic rainfall-runoff relationship. This study used back-calculated curve numbers (CNs) and Normalized Difference Vegetation Index (NDVI) to develop NDVI-based CNs (CN[subscript]NDV) using four small northeastern Kansas grassland watersheds with average areas of 1 km² and twelve years (2001–2012) of daily precipitation and runoff data. Analysis indicated that the CN[subscript]NDVI model improved runoff predictions compared to the SCS-CN method. The CN[subscript]NDVI also showed greater variability in CNs, especially during growing season, thereby increasing the model’s ability to estimate relatively accurate runoff from rainfall events since most rainfall occurs during the growing season. The CN[subscript]NDVI model was applied to small, disturbed grassland watersheds to assess the model’s ability to detect land cover change impact for military maneuver damage and large, diverse land use/cover watersheds to assess the impact of scaling up the model. CN[subscript]NDVI application was assessed using a paired watershed study at Fort Riley, Kansas. Paired watersheds were identified through k-means and hierarchical-agglomerative clustering techniques. At the large watershed scale, Daymet precipitation was used to estimate runoff, which was compared to direct runoff extracted from stream flow at gauging points for Chapman (grassland dominated) and Upper Delaware (agriculture dominated) watersheds. In large, diverse watersheds, CN[subscript]NDVI performed better in moderate and overall flow years. Overall, CN[subscript]NDVI more accurately simulated runoff compared to SCS-CN results: The calibrated model increased by 0.91 for every unit increase in observed flow (r = 0.83), while standard CN-based flow increased by 0.506 for every unit increase in observed flow (r = 0.404). Therefore, CN[subscript]NDVI could help identify land use/cover changes and disturbances and spatiotemporal changes in runoff at various scales. CN[subscript]NDVI could also be used to accurately estimate runoff from precipitation events in order to instigate more timely land management decisions.
