Land use GIS in a selected municipality
Sekanina, Michal ; Plánka, Ladislav (referee) ; Bartoněk, Dalibor (advisor)
The thesis content study of land use in municipality Lelekovice and its connection with software for geographic information system. It describes processing data especially historical cadastre maps, archival aerial imagery and orthophotos which were used for analyzing of this area. Analysis were performed in software ArcGIS. Appendixes of thesis are graphs and visualization of development of study area.

Evaluation impact of the landscape structures on erosion and runoff conditions in given catchment area
Švandová, Tereza ; Sobotková, Veronika (referee) ; Dumbrovský, Miroslav (advisor)
The aim of this Thesis is to determine the impact of landscape change and erosion in given watershed. This case is evaluating Kamenec cadastral area. Changes in crops and spatial distribution of the fields are evaluated first in 1954, when the monitored area was without agricultural cooperative farms and land was used in a smal land parcels. This was compared to the evaluation in 2015 when land was part of agricultural cooperatives and was used in large units. The changes in landscape and its use were imense. Land exploatation, heavy machinery and non conservation cultivation led to its soil compaction and deterioration of the K factor.To evaluate soil losses I used a method USLE and program ArcGIS

A study of erosion control system using biotechnical conservation measures
Moravec, Jiří ; Sobotková, Veronika (referee) ; Dumbrovský, Miroslav (advisor)
The objective of the bachelor thesis was the study of soil erosion control with application of system of semi-natural measures in chosen small catchment. Digital elevation model was generated and average soil loss was determined by ArcGis tools at each erosion parcel . Design of erosion control at chosen erosion risked locality was create in Microstation software and InRoads utilities. As a type of enviromental erossion control mesures was chosen a system of a earthfill dams with the sedimentation area in combination with grassing. The thesis efforts to point the differences between the possible optimal solution and a compromise solution which respects the requirements of agricultural entities. The solution respects the trend of water retention in landscape and use of low cost measures.

Změny krajinné struktury a jejich příčiny v katastrálním území Nasavrky
Korobková, Petra
The main subjects of this study are changes of landscape structure in the cadastral community Nasavrky (country district Chrudim, region Pardubice) in the time of years 1852 up to 2013. On the basis of datas from the second military survey (landscape structure of 19th century), the Czechoslovakian topographical map (landscape structure of 50s of 20th century) and actual topographical map and orthophoto map update by field research (landscape structure of the year 2013) were evaluated changes of land use with using geographic information system. The changes of landscape structure are described based on the development of area of eight land use categories (forests, arable land, permanent grassland, orchards and gardens, built--up area, water area, recreation area and other area). The largest changes were registered of categories arable land and permanent grassland. Ascertained informations about changes of land use can be used as materials in for example landscape planning.
