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.
Volumetric determination of weak and strong acid in the mixture.
Norková, Renáta ; Opekar, František (advisor) ; Jelínek, Ivan (referee)
The project is aimed to the study of the titration curves of the weak and strong acid mixtures. Purpose of the project is to compare titration curves computed on the basis of simple model, when neglecting influence of the solution's ionic strength , with experimental titration curve obtained through measuring under standard laboratory conditions. This comparison is carried out for one strong acid in the mixture with various weak acids, that differ in value of dissociation constant. How titration curves are influenced by the ratio of concentration of strong and weak acids is observed further.
