Angl. resumé

The target of this thesis is to project a precaution against a flood and erosion in the particular land arrangement. The cadastral unit of Dlouhá Stropnice has been chosen for this purpose which is interesting for its rugged topography and the river system from the erosion and the flood point of view. The description of the area is aimed on its location and its hydrological, geological, climatic and pedologic conditions. In the beginning it was important to consider the present situation of the erosion and flood danger in the cadastral unit of Dlouhá Stropnice. For the creation of the possible danger in this cadastral unit was used the universal equation of the soil loss caused by the water erosion according to Wischmeier and Smith. Thanks to results the problematic areas were defined. The result of this thesis is to project the nature close arrangement against flood and erosion and to evaluate their influence on the erosion and the water outflow in this area.

The graduation thesis analyzes water erosion issue, especially by calculating average earth annual loss using the Wischmeier Smith universal equation. Primary task was to assess and evaluate erosion phenomenon on the model basins' borderlines and review the hydrological and administrative teritorial units overlay from the perspective of rainfall runoff. Secondary task was to explore the possibility and suitability of increasing the rainfall erosion efficiency factor by doubling.

The thesis continues with the bachelor thesis which had dealt with preparation bases for simulation draining and carrying materials in SWAT model. Simulation should have been realized within basin of the Jenín stream, which watershed is 4,65 km2 large. SWAT model is primary developed for the larger watersheds where simulated values doesn't attain tolerances. Because of this is thesis focused on the methodic of simulation itself, discussion of the problem when is SWAT model almost useless for the small watersheds and presentation of the calibrated values which had served as basis for verification.

The aim of this work was the analysis of the current state od cadastral area Krásná. Available materials were collected, analyzed and evaluated. Procurations were proposed on the basis of these activities to improve conditions in the areas of soil conservation, water management conditions, the landscape environment and, last but not least, the transport system and access to land. Form and content were chosen so that the work could be used as a basis for a plan of common facilities.

This thesis solves problems of erosion protection in land consolidation on three projects of selected model complex land adjustment. The first part deals with the theory of land consolidation, water erosion and potential erosion protection applicable to the design complex of land adjustment. In the second part we discuss practical solutions for erosion control, its calculation and the proposed erosion control plan in relation to the collective model in various projects.

This diploma thesis examines the state of the Lisov stream and its basin. It also suggests the way of revitalization of the whole riverbed in given places. For better solution of this problem, the stream was divided into several sections, which are analysed both separately and as a whole. The basic information for the purposes of this diploma thesis were gained primarily from the survey of the given area. The evaluation was realized according to the findings and other maps which are freely available on the Internet. Thereafter there is a suggestion of the revitalization works which was made together with individual revitalization objects. This suggestion includes also the possible way of financing all these revitalization actions. There were several slopes set in the basin and the soil removals caused by water erosion were calculated for these slopes. The reason for including these data is that this diploma thesis puts emphasis also on the river sediments which are forming the riverbed of the stream too. At the same time there was another survey completed. It is related to the flood protection and the suggestion how to build up these necessary flood protections.

The topic of this master thesis is the solution of erosion protection on a complex land consolidation model. The first part deals with land consolidation, erosion, factor influencing erosion a erosion protection. The second part focuses on the cadastral of Záborná, where average soil loses on land blocks according to universal Wischmeier and Smith equation and CN curves are calculated. Organizational, agrotechnical and technical character of the erosion protection is suggested for the cadastral.

This dissertation aims primarily at determining the energy yield that can be produced, if certain species of energy crops are grown (under various regimes of fertilizing and sowing) by the Faculty of Agriculture, the University of South Bohemia, on a university's trial parcel. Zea mays L. is one of the energy crops chosen for the experiment; it is grown on a large area in the Czech Republic nowadays. Perennial crops of Phalaris arundinacea L., Elymus elongatus subsp. ponticus cv. Szarvasi-1 andMiscanthus × giganteus were also chosen for this experiment. Based on the collected data, a risk of erosion provoked by the above-mentioned crops has been determined by using USLE method. The crop stands and the soil have been analysed too. This analysis has focused on the organic matter evaluation, by using a brand new method. Last but not least, occurrence of Carabidae beetles has been studied and evaluated within the research; they are considered bio indicators of the environmental conditions. Our experiment has shown that Zea mays L. is the most high-yielding species. On the other hand, Phalaris arundinacea L. has not produced positive results; the most high-yielding variation of it only made a half yield of Zea mays L. In contrast to Zea mays L., grass species of Phalaris arundinacea L. andElymus elongatus have had an extraordinary anti-erosion capacity. Studying the amount of primary organic matter in the soil, we have found almost double amount of it in Miscanthus × giganteus andZea mays L. crop stands, compared to another two species. Monitoring oxidation reaction kinetics of the primary organic matter, we could count the oxidation speed constant of k. There have been dramatic differences between the individual soil samples. However, the data file is too complicated to draw the general conclusion from. On the other hand, evaluating the data gathered by studying Carabidae beetles and the environmental values of the crops stands, we have found out the crop stands are not too valuable from the environmental point of view. We have found out the perennial species have got an extraordinary anti-erosion capacity. We recommend Miscanthus × giganteus and Elymus elongatus, in particular, as an alternative to corn, especially to regions highly endangered by erosion.
