Comparison of the newest methods for computation of water erosion
ŠESTAUBEROVÁ, Martina
The conspectus of this thesis is to explain erosion matters, especially water erosion problems. The introduction part explains the water erosion, its origins, impacts and some erosion control measures, which can precisely this sort of water erosion or at least limit its consequences. The main goal of this thesis is to compare and contrast available methods for the calculation of water erosion. In this work we can find the basic methods for calculating the average annual erosion of soil and the following selected models provide the basis used to calculate the instantaneous erosion of soils. The basic methods for calculation of average annual erosion of soil are then USLE and RUSLE methods. The most available possible models were selected for the purposes of this thesis.

Návrh protierozní ochrany půdy v katastrálním území Jedovnice
Klimešová, Martina
In this master's thesis Suggest the protection of soil erosion in the cadastral area Jedovnice, I perform the analysis of specific factors influences erosion processes and I find the size of the average soil runoff. It also determines by two different methods (old and new) degrees of erosion threat. The detected values degrees of erosion threat, according to different methods differ significantly. Methods differ mainly in the value of R-factor and the limits of permissible soil loss. Main objective is on the average values soil runoff, propose appropriate antierosion measures with regard to the permissible loss of land. I suggest, for both calculations by different methods, organizational erosion control measures. At the end I evaluate two variants of the selected organization erosion control measures and compare their effect on soil erosion in Jedovnice. Keywords: soil protection, water erosion, erosion control measures, USLE

Comparison of the latest methods for calculations water erosion
KOVÁŘOVÁ, Kristýna
The substance of this thesis is to explain erosion matters, mainly water erosion matters. The opening part explains the water erosion, its causes and consequences, and also possible antierosion measures, which can partly scumble the water erosion or at least reduce its consequences. The main goal of this thesis is to compare and contrast available methods of water erosion calculation. What is presented here are the methods of calculation of average annual soil wash-away and consequently the selected models which serve for calculation of immediate soil wash-away. Methods for calculation of average annual soil wash-away include USLE method and RUSLE method. Only the most available possible models of calculation the immediate soil wash-away were selected for the purposesof this thesis. The closing part of the thesis evaluates teoretical findings in the particular project of land consolidation. Convenience to a given drainage area was considered for individual models of immediate soil wash-away. While calculating the average annual soil wash-away the individual patterns of the USLE method were used. This method developed gradually and individual results were compared.
