Aplikácia a optimalizácia agroenvironmentálne-klimatických opatrení v konkrétnom podniku
Kačníková, Kornélia
This thesis is aimed on application of agri-environment-climate measures (AECM) as a helping tool for soil protection, in a cooperation with ZEMASPOL Uherský Brod a.s. company. The first part of literary review describes the development of AECM in the context of Common agricultural policy and Czech Republic, the second part is focused on real benefits of chosen measures (biostrips and grassing). The practical part is aimed on evaluation of soil vulnerability by using universal soil loss equation. By application of the measures, the L.S factor is reduced by biostrips and C factor is reduced by grassing, which both have a positive impact on final soil loss. In the last part of the thesis, the measures are also economically evaluated.

Vyhodnocení erozní ohroženosti pozemků vodní erozí na vybraném území s využitím nástrojů GIS
Bartošek, Ondřej
This diploma thesis focuses on the analysis of the vulnerability of land to water erosion in the catchment area of Sloupnicky potok in the district of Usti nad Orlici. The first part of the thesis deals with the topic of soil degradation. The main part is devoted to soil erosion. Part of this work is also the characteristics of the area of interest. The final part of the work deals with the calculation of the factors of the universal equation USLE and the determination of the average long-term loss of soil by water erosion before and after the design of anti-erosion measures. All operations were performed using ArcGIS, USLE2D, LS converter software.

Identification and measurement of rill erosion in the farm landscape
Vaňousová, Martina ; Larišová,, Lucie (referee) ; Sobotková, Veronika (advisor)
Due to water erosion, there is a loss of soil, reduced fertility, soil prices, increased costs in ag-riculture and water management due to clogging of watercourses and reservoirs and affecting the quality of water resources, threats to urban and infrastructure. One form of water erosion is gully erosion. Three erosion gullies were selected in the bachelor thesis. Their areas of interest and the methods used were described. In the case of erosion gully, their axes and transverse profiles were measured using soil erosion bridge. Volumes of eroded soil were obtained by eva-luating photographs taken with a camera from soil erosion bridge. The results show that from the erosion gully in the Embassy Ústí with a total length of 206.5 m, an average width of 2.8 m and a catchment area of 2.6 ha, soil with a total volume of 69 t was removed. In the Ostrov Em-bassy, the total soil loss from the 201 m long erosion gully with an average width of 1.8 m and a catchment area of 1 ha was set at 45.4 t. In the Embassy of the Sebranice, the total volume of soil removal from the erosion gully 217 m long, average width 2.3 m and the catchment area 9.8 ha was determined to be 45.2 t. Soil samples were taken near the erosion gullies – it was deter-mined bulk density and grain size curves.

Analýza ohroženosti pozemků vodní erozí ve vybraném území s využitím programu ArcGIS
Šabata, Tomáš
The diploma thesis is focused on evaluation of the average long-term loss of soil by water erosion in the cadastral areas of Oslavany and Padochov. To determine the erosi-on risk of agricultural land before and after proposal of anti-erosion measures, the uni-versal USLE equation according to Wischmeier and Smith was used. The programs ArcGIS, LS CONVENTER, USLE 2D and MS Excel were used to calculate individual factors. All the map documentation was created by using the program ArcGIS.

Using the Erosion Potential Method in the Czech Republic
Hloušek, Jakub ; Larišová, Lucie (referee) ; Dumbrovský, Miroslav (advisor)
The aim of this thesis was the evaluation of the loss of soil for the area of interest, located in the north-western part of the Němčického basin, in the district of Blansko. The calculation was made using two methods, namely erosion potential method (EPM), commonly used in Serbia and the Wischmeier-Smith universal soil loss equation (USLE), used in Czech Republic. Finally, both of these methods were compared with each other. Both methods use a different method of calculation. USLE method utilizes the universal equation for calculating the long-term average soil loss per year (G), the EPM method utilizes equation for specific average annual soil loss (Wsp, Wy). The calculation was performed with both methods in program ArcGIS while the USLE method was also supplemented with calculation of the factor (LS) with USLE2D program. When comparing the soil loss each of evaluated areas, the EPM achieved higher values of soil loss in the most of them. In contrast to the USLE method, the EPM the total loss of the soil from the evaluated areas also accounted the soil loss from forest areas. In terms of accuracy of the achieved real world results, it was determined that the conditions in the Czech Republic are more suitable for the USLE method and not only due to more accurate data input, but also because with EPM there is no factor that would better reflect the topographic factor and conditions of surface runoff in the territory.
