Studie a posouzení protierozních opatření v katastrálním území Záborná
BŮŽKOVÁ, Jana
The diploma thesis deals with an assessment of cadastral territory, which is going through a complex land consolidation. For these purposes, the cadastral area Záborná, that is located in the Vysočina Region, was selected. The main objective of this work is to compare the current state of the territory, in terms of erosion, with the area where the erosion control measures were proposed. Erosion will be calculated using by Wischmeier-Smith's universal soil loss equation. In this cadastral area, it will be necessary to assess in terms of climate, geology and hydrology.

The soil erosion and maize growing in Czech Republic
KOMÍN, Jiří
The thesis was conducted balance the possibility of growing corn while fighting water and wind erosion. The results of the study of theoretical possibilities and practical impact for producers, particularly economic drilling can be recommended mainly erosion belts and mulch sowing maize. Both of these methods are effective, but it is necessary to supplement the correct procedure when setting up the stand of corn. The rule for stand establishment corn on the slopes of these three principles: corn crops sown along the contour, after sowing fundamentally dont roll and sown corn prefer deeper, at least 5cm. At sufficiently deep soil preparation (about 10 cm) gave, after sowing of maize plot different heights furrow which slow surface runoff of water and promote a better infiltration. At the same time, thanks to its larger surface ensures faster warming of the soil and thus faster germination of corn crops. As soil protection technology with significant erosion control effects can be recommended depending on specific soils shallow tillage with simultaneous defray organic matter to the soil followed by planting, sowing no- drill with disc coulters directly into the raw soil after the previous crop, or sowing / planting mulch crops or forecrop. Another option is sowing the main crop with undercrop in between rows (maize undercrop winter rye), or tape sowing untreated soil. Such as erosion control technology is also certified by the reduction of row spacing in corn.

Návrh protierozních opatření v modelovém projektu komplexní pozemkové úpravy
NOVÁKOVÁ, Tereza
The topic of my thesis deals with the proposal of erosion control measures in a model comprehensive landscaping project. Literature research is used to explanation of basic terms, to familiarization with problems of land adjustment, water erosion and erosion control measures, but also with laws and regulations. The second part is dedicated to the proposal of erosion control measures. In program ArcGIS have been identifited 16 drainpaths, for which have been calculated surface drain and proposal erosion control measures. The results are processed into clearly tables.

Erosion danger of soil blocks with selected crops and recommendation of suitable cultivation against erosion
JIRSOVÁ, Monika
This thesis deals with different types of soil degradation under the conditions in the Czech Republic. The first part is focused on the evaluation of the causes and course of degradation of soils in the present time. Among the most serious degradation factors may be included the following: pedocompaction, dehumification, land appropriation, bad infiltration, water and wind erosion. In the Czech Republic, only water erosion alone threatens 42% of all agricultural land. In the thesis organisational, technical and agrotechnical anti-erosion control measures are summarised. Their utilisation, efficiency and sophistication are also described. In the next part of the thesis there are six specific land blocks in the same farm in South Bohemia presented. Each of these blocks has a different acreage, the average slope, the crops cultivated and different representation of strongly threatened and moderately erosion-threatened vulnerable areas. The thesis evaluates the number of plants per 1 sq. m, the condition and density of the growth due to the erosive threat to all of these localities.

Solution erosion protection on a Complex Land Consolidation model
SVOBODOVÁ, Pavlína
The aim of this work is to explore the area of the Complex Land Consolidation Poněšice in the view of the pedology, hydrogeology and climatology. Further make a erosion threat calculations using the USLE and Curve Number method and afterwards review the application of the erosion control measures in another section of the chapter Main terriorial systems. In conclusion, to estimate the economic aspects of the proposed measures.

Erosion threat of landscape in the context of sustainable agricultural system
SIMANDLOVÁ, Veronika
Currently there is about 54% of agricultural land at risk of water erosion. A prerequisite for sustainable agricultural development is the implementation of soil protection. Erosion control measures represent a set of measures that, in addition the priority function of reducing the losses of the soil, significantly affect the water conditions in the countryside. The topic of my thesis is the erosion threat of landscape in the context of sustainable agricultural system. The first part focuses on the literature search related to sustainable agriculture, soil erosion problems and possibilities of protection ALR (Agricultural Land Resources). The practical part is concerned with a particular territory in which comprehensive landscaping erosion control measures have been taken. The aim was to assess the condition of the above mentioned area before and after the implementation of measures. Furthermore, individual parameters were evaluated, as well as the types and localization of erosion control features in the area of interest, comparing them with the project documentation and a plan of joint facilities.
