Simulation model of reservoir system in Dyje river basin
Buršík, Lukáš ; Kozel, Tomáš (referee) ; Menšík, Pavel (advisor)
This Bachelor’s Thesis is focused on creating a simulation model of the reservoir system in Dyje river basin. The reservoir system consists of four reservoirs: Jevišovice and Výrovice on the Jevišovka River, Vranov and Znojmo on the Dyje River. The HEC-ResSim program was chosen to create the simulation model. The simulation model is aimed at reservoir storage function and the calculation works with the daily step. Real data of individual reservoirs and real flow series of three measuring profiles are used. The first part of work deals with simulation models and reservoir functions in general. Then the used program is described in a greater detail. The second part deals with selected system of reservoirs, watercourses and measuring profiles. There can be found a description of creating the model itself in the selected program in the third part. The description is complemented by selected examples of physical data and management rules. The last fourth part is devoted to a summary of the results, which are again accompanied by selected examples.

Long Term Discharge Prediction in River Hydrometric Profile
Šelepa, Milan ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The diploma thesis is focused on the long term prediction of mean monthly flows in hydrometric profile for purposes of reservoir control optimization and optimization of reservoir systems. Discharges were predicted using by artificial neural network method. Predicted flows were statistically evaluated by relevant coefficients and then compared with the measured flows for given river hydrometric profiles.

Modelling the hydrodynamics and water quality of the Vltava river reservoir cascade
Růžička, Martin ; Hejzlar, Josef ; Jarošík, Jiří
Mathematical modelling is an efficient tool for evaluation of impacts of human activities and environmental changes on water quality in rivers and reservoirs. This contribution describes simulations of water quality in the Vltava River reservoir system, namely cascade of reservoirs Hněvkovice, Orlík, Kamýk, Slapy, Štěchovice, and Vrané. The two-dimensional water quality model CE-QUAL-W2 was used for this task over years 2000 to 2003. Sensitivity analysis, calibration, and evaluation of the model were done. The model gave good results in particular for hydrodynamics, water temperature, and conservative constituents because of good quality of available hydrological and meteorological input data. The accuracy of results was strongly depended on the quality of input data and sampling frequency. Minor problems occurred in water quality simulations based on monthly input data in periods with fluctuating discharges.
