Bathymetric Survey Processing and Volumetric Analysis of the Brno Reservoir
 Dzoba, Kryštof ; Hamal, Rostislav (referee) ; Marton, Daniel (advisor)
This bachelor thesis is devoted to the processing of bathymetric data and volumetric analysis of the Brno reservoir and the creation of digital terrain models. Based on these models, bathygraphic curves are created. Subsequently, a simulation of the reservoir operation is carried out to determine the effect of the change of the bathymetric curves on the reservoir capacity. The first part of the thesis is devoted to introduction to bathymetry, the possible ways of collecting bathymetric data and describing the measurements made in the practical part of the thesis. The next part is devoted to the description of the methods used for data processing, the creation of digital terrain models and the creation of bathymetric curves. In the last part the interpretation of the results is made.

Volumetric and Evaporation Analysis of the Landštejn reservoir
 Hánová, Karolína ; Bednář, Martin (referee) ; Marton, Daniel (advisor)
This bachelor thesis focuses on the volumetric analysis and estimation of evaporation from the water surface of Landštejn reservoir. The main objective is to determine new bathymetric curves of the reservoir based on the most recent bathymetric survey of the bottom and then to estimate the amount of evaporated water for a selected period. To achieve these objectives, ArcGIS tools will be used to create a digital terrain model that will allow accurate calculation of the bathymetric curves through volumetric analysis. The amount of evaporation will be determined using selected empirical formulas and simple balance analysis, taking into account the standard ČSN 75 2405 concerning the water management design of reservoirs and comparison with data from the Czech Hydrometeorological Institute. The practical part of the work includes the creation and evaluation of a digital terrain model of the Landštejn reservoir and subsequent estimation of evaporation based on average temperatures and other meteorological data. The results show new bathygraphic curves and provide accurate estimates of the volume of water evaporated from the reservoir over the specified period. This work contributes to a better understanding of the hydrological processes in the Landstejn reservoir area and provides important input for more effective water management planning and management.
