Ohrožení zemědělských půd vodní erozí v katastrálním území Stanislavice

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
