Návrh protierozních opatření v katastrálním území Bořitov
Šmarda, Zbyněk
The thesis called "Design of erosion control measures in the cadastral area of Bořitov" focuses on the issue of soil erosion. Erosion of soil is a natural process in which by working of water, wind, snow, alternatively other agents the surface of soil is eroded, soil fractions are transported and their sedimentation takes place. In my thesis, I concern myself with determination of loss of soil by effect of erosion in the cadastral area of the Bořitov municipality. The thesis is divided into two parts. The first part of the thesis is prepared in the form of a literary research. Based on the study of expert literature, the first part describes the issue of soil erosion and erosion control measures. The second part concerns with an analysis of current conditions and an analysis of the current state of use of the area with respect to its endangerment by water erosion. Further, it evaluates individual erosion factors, determines threat of erosion using an universal equation following Wischmeier and Smith, it designs system of erosion control measures and states effectivity of the designed measures.

Návrh ochrany půdy před vodní erozí v katastrálním území Stanislavice
Glac, Mateusz
Erosion is a global problem, which threatens one of the most valuable natural riches of the world, the soil. Erosion is a natural process that has been existing since the very be-ginning; this process is characterized by eroding the soil surface, transporting the soil particles, and the subsequent sedimentation of these particles. In its natural form, ero-sion does not present a big problem, since there are small losses of soil particles, which are sufficiently completed by newly formed particles from the subsoil. The real problem is identified in accelerated erosion which is caused by environment unfriendly human intervention in nature and landscape. In the Czech Republic, around 50 % of arable land is exposed to water erosion. In most cases, it is still a consequence of the collective farming period, when bounds, hedgerows or alleys were ploughed. It is important to be aware of the fact that this situ-ation is not viable for a long period and that it needs solution. The submitted thesis that is divided into two parts focuses on the matter of water erosion in the cadastral area of Stanislavice. The first part, which is theoretical, deals with a review of literature that generally discusses the concept of erosion, its division, causes, consequences, and possible anti-erosion measures. The second part is related to the practice and it is particularly linked to the erosion issue in the cadastral area of Stani-slavice. It also involves an analysis of the current situation and conditions in the cadas-tral area of Stanislavice, using the Wischmeier-Smith equation that defines the degree of land erosion risks. In the conclusion, appropriate erosion control measures are designed in order to diminish the erosion rate.

Návrh ochrany půdy před vodní erozí v katastrálním území Hrotovice
Franková, Zuzana
The diploma thesis The proposal of the soil protection against water erosion in the cadastral area Hrotovice focuses on issues of water erosion of soil in the cadastral Hrotovice proposal and erosion protection on the arable land. The first part focuses on the description of erosion in general, its distribution, causes and consequences of a literary review. Also described are natural conditions specified locations. Second, that the practical part, is specifically focused on water erosion in the cadastral Hrotovice. There are analyzed various erosion factors, according Wischmeier - Smith equation to calculate the average long-term loss of soil and determined the degree of erosion threat of land. Finally, it formulated a draft measure before the effects of water erosion and determined the effectiveness of this proposal.

Návrh ochrany půdy před vodní erozí v katastrálním území Jinošov
Vránová, Dana
The diploma thesis "The proposal of the soil protection against water erosion in cadastral area Jinošov" focuses on issues of water erosion on the arable land and proposal of protection against erosion. In the introduction of the thesis is presented erosion of soil as literary research and also there is an analysis of the natural conditions of research locality. In the practical part there are evaluated factors of the erosion, then average long-term loss of soil caused by water erosion, according to Wischmeier-Smith equation and also threat levels of eroded soil. Furthermore, there is created the proposal of the measure against the effects of water erosion and determination of the efficiency of this proposal.

Návrh ochrany půdy před vodní erozí v katastrálním území Kobylí
Loveček, Martin
Erosion is global issue. In Czech republic, soil is threatened mainly by water erosion, approximately 50 %. This phenomenon causes irreversible soil loss and degradation. In the soil there are chemical and physical changes and changes of structure and texture. The changes are very dangerous because distinctly decrease soil fertility. In thesis is solved soil loss by water erosion in cadastral area Kobylí. Firstly I deal with concept of erosion and its types. Further I describe calculation methodology of water erosion by using Wishmeier-Smith equation and possible methods erosion control measures. In conclusion I evaluate soil loss and I suggest suitable erosion control measures on endangered areas.

Návrh ochrany půdy před erozí v katastrálním území Olbramovice u Moravského Krumlova
Benešovská, Lenka
Soil erosion is a natural process, whose progress is accelerated by reckless and insensitive human interventions to the nature and landscape. Erosion is a global problem, which unfortunately is now starting to give priority and attention it deserves. Erosion can be characterized as a natural process, during various factors break up the soil surface, transport and sedimentation of soil particles. It is important to note that the correction of such much degraded land is expensive and time-consuming business, and in some cases impossible. The thesis was divided into two parts. The first part deals with the problem of erosion in general, including its disaggregation, the causes, consequences and possibilities of counter-erosion measures. In the second part is solving specific territory Olbramovice near Moravian Krumlov. An analysis was made of the current state of the territory, also was determined by calculating the loss of soil erosion and created a proposal alternative counter-erosion measures and then determine their effectiveness. In the Czech Republic is threatened by water erosion over 50% of agricultural land and over 14% by wind erosion. Status of our soils is alarming and our behavior towards it is irrelevant. This degradation of the soil can be the best describe with the statement by the US President Franklin D. Roosvelvelt "nation that destroys soil, destroys itself."

Ohrožení zemědělských půd vodní erozí v katastrálním území Stanislavice
Glac, Mateusz
Erosion is a global problem that has been occurring for a long time. In the Czech Republic the main type of erosion is the water erosion, 50 % of the land is affected by it. Erosion can be described as a natural process, which results from the effect of various factors eroding the soil surface, transport of soil particles and the subsequent establishment. This process causes the degradation of land that is described as soil degradation. The erosion can appear in different places. For example, in the agricultural soils that are not cultivated the erosion it is not paid attention because it has a soft effect and often not harmful, however, in the agricultural soils that are cultivated, where the erosion can be really dangerous, it is necessary to pay attention to it. In this bachelor thesis a study related to the water erosion in the cadastral of Stanislavice is carried out. In the first part of my thesis the erosion is described, a bibliographic review is presented, providing the general concept of erosion, its division, the causes of it, and its possible consequences. In the second part a description of the current status and conditions of the water erosion in the cadastral of Stanislavice is listed. The following part of my thesis is related to the analysis of the different factors after having used the Wischmeier-Smith equation. These factors have been calculated for the long-term loss of soil caused by water erosion. At the end, the resulting values from the Wischmeier-Smith equation have been used to determine the degree of soil erosion for individual plots.

The evaluation used sowing methods and their influence on the values of the C factor
JÁNOŠÍK, Vojtěch
This bachelor thesis covers and evaluates the possibilities of using sowing procedures in the contemporary Czech agriculture. The first part of the thesis analysis erosion and anti-erosion protection. Particular agricultural production areas and universal Wischmeier-Smith equation, calculating soil loss from land, are described in the second part. The effectiveness of anti-erosion of some selected sowing procedures is analysed at the selected basin of Lačnovský stream. The area is located at the South Bohemia on the border with Vysočina country.
