Využití systémů přesného určování polohy stroje pro řízení nasazení techniky

Knotek, Jan January 2019 (has links)
This thesis is focused on utilization of GPS navigation especially in agricultural pra-xis. The main goal of this work is putting on and controlling of agricultural equipment at resolution of anti-erosion measures. These measures are reaction to the so called antiero-sive regulation. In the theoretical part is shortly described GPS system and the work with geodates. Then there are described methods limiting water erosion of soil. Sub-sequently there is shortly described a problem of erosion measures and complex of the information necessary to the utilization of GPS navigation while fighting with this issue. In the practical part of this work was formed the method for the creation of anti-erosion measures. According to this method was subsequently developed the procedure to ad-justment SEO DPB. This method was subsequently apllied and tested in POOSLAVÍ Nová Ves, agricultural kooperative. At the conclusion of the work is evaluated by ma-nagement on the thus modified DPB and then there are described problems that occured while creating these anti-erosion measures. For that reason are drawn recommendations for putting on and controlling of agricultural equipment at resolution anti-erosion mea-sures.

Návrh protierozní ochrany půdy v katastrálním území Jedovnice

Klimešová, Martina January 2014 (has links)
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

Využití a ochrana území opatřeními pozemkových úprav

Dostálek, Antonín January 2014 (has links)
The title of my thesis is "The use and protection of a territory by means of land adjustments". I focused on the cadastral area of Kněžpole near Uherské Hradiště which is situated close to my domicile. The first part of the thesis comprises of a literary research and it tackles the issue of land resources and land adjustments in general. It also describes the historical development of land resources, their composition and protection. The second part consists of an analysis of the aforesaid area, focusing on the particular natural characteristics, the current status and the evaluation of the particular factors influencing erosion and drainage. Water erosion is handled according to the handbook "Anti-erosion protection of land" published in 2005 and according to the methodology described in "Protection of agricultural land against erosion", published in 2012. Having discovered that the allowable loss of soil has been exceeded, we have suggested several anti-erosion measures to protect the most endangered land blocks. Furthermore, the effectiveness of the suggested measures has been assessed. The final part of the thesis offers an evaluation of the impact of the suggested measures on areas used in agriculture.

Návrh ochrany půdy před erozí v katastrálním území Olbramovice u Moravského Krumlova

Benešovská, Lenka January 2015 (has links)
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."

Návrh protierozní ochrany půdy v katastrálním území Petrovice u Blanska

Klimková, Marie January 2015 (has links)
This master's thesis "Design of soil erosion control measures in the cadastral Petrovice u Blanska" deals with the problems of erosion on agricultural lands. A worldwide problem is the loss of soil from the agricultural areas, it is caused by accelerated erosion. Erosion causes soil degradation and reduces production ability of lands. Erosion silt cause damage in urban areas and clog waterways. The first part of this thesis is focused on erosion processes and ways to reduce loss of soil by erosion. Other parts are focused on assessment of soil erosion vulnerability in the chosen cadastral area. The objective of the present work was to determine the degree of soil erosion caused by water and there were designed appropriate erosion control measures for threatened lands. The effectiveness of erosion control measures was evaluated after their design. Applying measures, it was achieved a reduction of long-term average annual rates of water erosion below the limits of acceptable rates of soil erosion.

Návrh studie protierozních a protipovodňových opatření v povodí Mřenkového potoka

Grossová, Eva January 2015 (has links)
This thesis "Suggestion study of erosion and flood protection measures in the catchment Mřenkového area" processing based on a field survey obtained information on the area of interest a draft study of erosion control measures in the sub-basin. A well-designed anti-erosion measures are multifunctional effect. Not only restrict washes soil, but they slow down surface runoff and increase water retention in the landscape. Part of the literature review is a general description of how the issue of erosion and flood protection issues, including the introduction of the concept of erosion, floods, their causes, implications and possible ways of action. In the practical part of the researcher conducted geodetic survey of the flow path through the culvert, and then the program MOUSE sugessted nonkapacity culvert under the road for N - year flows. Continued technical proposal and agro-technical measures sub-basin Universal soil loss equation long-term water erosion under Wischmeiera-Smith. From the resulting values Wischmeier-Smith equation was determined by the degree of soil erosion risks for individual erosion sealed units. It was also set up crop rotation to reduce the impact factor of protective vegetation to reduce water erosion and surface runoff were designed erosion furrow.

Historický vývoj struktury krajiny v kontextu s potenciální ohrožeností půdy vodní erozí / Historic analysis of landscape pattern in context of water erosion risks

Freiman, Jan January 2016 (has links)
Abstract Disertation Historic development of landscape structure in the context of the potencional treatened earth water erosion, discribes the process of changes with usage landscape, which took place in cadastral area Vráž u Berouna, Tuchoměřice and Lanžov in královohradecký region. Total expanse all of these areas is 2 315,8 ha. Selecting areas was held on the planned complex landscaping, becouse of practical use of the change of landscape, which had an impact on water erosion. Pictures, which were chosen for this job are from 1952, 1975 and 2003. The reason for choosing these pictures are equal distance and that the most important influence on remoulding the landscape which have taken place since the 50s of the 20th century due to agriculture collectivization. Content of literary reserch is to approach the basic concepts, which have connections with the landscape and the assessment its structure including USLE, which deals with the calculation of erosion. For calculation of processes and changes in the landscape exist many tools and methods. In this work ,is analysis and calculation of erosion done with help of geographic informatiom system (GIS). Very important part of this wokr is to interpret the results in the form of map output, tables and graphs.

Šetření větrolamů ve vybraných katastrálních územích z hlediska druhového zastoupení dřevin a jejich zdravotního stavu / Research of windbreaks in a chosen cadastral area from the point of view of woody plants species´ representation and their health condition

Knoblochová, Martina January 2016 (has links)
This thesis evaluates the current state of selected wind breaking types, looking at their species composition, condition and functionality. One of the most efficient precaution against wind erosion are wind breaking swathes of woodland, windbreakers. These woodlands protect adjoining land against wind erosion of topsoil, blowing away snow cover as well as lowering water evaporation. The right position in the landscape, species composition and a good state are important for windbreakers to fulfil the above mentioned function. In the Czech Republic, 29% of farmland is badly affected by wind erosion. The most affected areas are situated in the South Moravian region. For the purpose of this dissertation work, two areas were chosen. Both of them are situated in the district of Znojmo, where the highest level of wind erosion is found. Area 1 lies in the districts of Břežany, Čejkovice and Božice. Area 2 lies in the districts of Velký Karlov, Hrádek and Křídlůvky. In order to investigate suitability of current windbreakers, the state of potential natural vegetation, climate, geological, paedological and hydrological conditions will be investigated in both of these areas. For the assessment of the effect of windbreakers, methodology after Podhrázská (2008) was used. This methodology allows assessment of these trees as individual linear elements, but also as a part of a network of these elements. The assessed criteria will be, for example: position in the landscape, species composition, age, functional type, height, width and the number of rows. Furthermore, horizontal and vertical parameters will also be investigated. For the evaluation of the functionality of the network of elements, it is also crucial to look at the tree orientation, their position in relation to the terrain and the direction of the wind. Moreover, the distance between individual woodlands also plays a significant role. The effect of windbreakers on the landscape will be further assessed using classification system after Kolařík (2005). Over the course of this project, 22 windbreakers were selected for evaluating their functionality and a proposal for their re-establishment in the future was suggested.
