Land adjustment evaluation in light of soil protection in Southern Bohemia.
KOULOVÁ, Lucie
Student thesis deals with soil conservation from effects of water erosion. In most territories, where land adjustment were done still, only mild erosion threat was found out and designed against {--} erosive measures were consequently minimal in these areas. There were mostly expulsion of maize from crop rotation, grassing or projection of a new rural road so as it interrupts slope. For example of such land adjustment there was complex land adjustment Vitín adduced and evaluated. Land adjustment Horní Stropnice was chosen for more detailed solution, there was a higher erosion threat found out by calculation of soil transport. The area was split in blocks, in which soiltransport was counted by means of Wischmeier-Smith equation for various values of factor R. Then soiltransport after realization of against {--} erosive measures was counted. Component against {--} erosive measures were evaluated and their execution in terrain was found out. Results show a problem with determination right value of factor R and a fact, that designed against {--} erosive measures stay mostly unimplemented.

Land adjustment evaluation in light of water protection in Southern Bohemia.
FRITSCHOVÁ, Hana
The aim of the thesis is to evaluate effects of natural and human activity on water quality of Budsky stream basin, futher assessing current water protection and proposing improvements in the form of differential protection zones. The basin is located on Besednice, Soběnov and Malče cadastral areas and extands to second grade of a water supply protection zone of Rimov reservoir. During terrain reconnaissance of the area were all the factors that could contribute to impaired quality of water in the basin taken into the account; from point source pollution to signs of erosion on the slopes of the basin. Futhermore the link between agricultural pollution, agricultural land erosion, land consolidation and protection of water was explained. Also pedological, hydrological and climate researches were conducted. The result is a redefined design of the water protection zones in question.

Prehistory and history of human impact on landscape relief: And overview of current directions in the study and the importance of case studies
BUMERL, Jiří
Humans became an important factor in the development of Holocene relief. They began to significantly influence a plant cover and retention of the landscape with the advent of agriculture. The consequences of deforestation and an economic land use on erosion and accumulation processes are evaluated by comparing case studies from areas of Germany, Czech Republic and Poland. The main erosive processes belong to the end of Eneolithic, Late Bronze Age, the end of the Roman Period, and early Middle Ages in the area of interest. On a microscale, a stronger influence of archaeological situations arisen before the start of the erosion events and a substantial reduction of artefacts stored in situ can be expected.

Application of intercropping as a stabilizing element against erosion washes away
KUKAČKA, Vladislav
The thesis was focused on the application of theorethical knowledge about catch crops and their influence on water erosion in practice. Its task is to evaluate the effect of the inclusion of catch crops in crop rotation in light of occurance and extent of water erosion on the example of agricultural enterprise ZEPHYR Františkovy Lázně, s.r.o. The task is also assessment of the possible combinations of crops and catch crops and suggestion for their use in middlegrowth period. The universal equation for calculation of erosion wash by Wischmeier and Smith was used to evaluate and calculate an erosion parameters for a given locality. The result of this thesis is reduction of soil loss by 26 % on lands with catch crop usage as a stabilizing element, compared to the classic conservative rotation of crops.

Solution of soil protection from erosion in model catchment - Zvíkovský stream
ŘEHOUT, Jan
The theme of my graduation theses is a solution of the soil protection from erosion on the model catchment of the Zvíkovský stream. The aim of this work is canvass of the catchment Zvíkovský stream in the view of the pedology, hydrogeology, climatology and calculate the soil loss from the areas in consequence of the water erosion. I used the equation losses of the soils from the area according Wischmeier and Smith and the assesment of the transporting the sediment runoff according Williams and Berndt which was calculated with the help of the programme ERCN {--} the enumerations required for the suggestion of the precautions from erosion. The map basis of this work is the basic map of the Czech republic 1: 10 000 and the water utilization map of the Czech republic 1:50 000.

An Impact of Erosion on Soil Quality
HOSNEDL, Pavel
Nowadays, erosion is a global problem. This thesis is aimed at studiing the impact of erosion on the soil quality, especially at humus content in soil. Humus content and humus quality is usually used as a criterion for assessing a soil quality. The proposal of methodology for monitoring of humus content change in time and dependence of its content on land management and steepness of slope is a part of the thesis. This thesis is written as a literary summary of studies which have been done so far.
