Špaček, Stanislav ; Holomek, Michal (referee) ; Paseka, Stanislav (advisor)
The aim of this bachelor thesis is to characterize the area of interest, the municipality Hlinsko, to define the decisive factors determining the flood hazard of the intravillage of the municipality, to determine the critical points and the corresponding critical profiles, to define the erosion assessment areas and to define the erosion hazard on them. Subsequently, propose erosion protection organisational, agrotechnical and technical measures and appropriate erosion protection seeding practices. In the introductory part of the work, the existing knowledge on the subject and the procedures for determining the surface runoff values and the erosion hazard rate were defined. Subsequently, an analysis of the study site was prepared and in the final part suitable water management and erosion control measures were proposed.

Determination of the functional volumes of the reservoir considering input data uncertainties
Paseka, Stanislav ; Doležal, Petr (referee) ; Szolgay,, Ján (referee) ; Marton, Daniel (advisor)
Damaging changes and interventions in the water cycle in our landscape caused mainly in the last century together with uncertainties from climate change are the cause of more frequent occurrences of hydrological extremes. In Hydrology, the most urgent problem is that the values of the long-term mean flows are decreasing in rivers as well as the yield of groundwater sources, but on the other hand, we cannot forget to the problem of extreme floods. In these consequences developing methods and tools to uncertainty analysis of the reservoir yield and of the reservoir flood protection is very important, useful and desired. The main aim was to determine the functional volumes of the reservoir considering input data measurement uncertainties and to quantify them and was explained how uncertainty took into account in results. The active storage capacity was determined from the historical series of monthly flows that were affected by uncertainties, next were applied on water evaporation, seepage losses of the dam and morphological volume-area curves. The simulation-optimization reservoir model was developed and temporal reliability as reservoir yield performance measures was applied. This model will extend the existing UNCE_RESERVOIR software. The flood capacity was determined from random flood wave variations were obtained by repeatedly generating uncertainty on the flood hydrograph. Software was developed based on the modified Klemes method, which was able to transform flood waves. The measurement uncertainties of data inputs were created using Monte Carlo method in both softwares. By connecting two softwares, the functional volumes of the reservoir under conditions of measurement uncertainties were complexly determined. The case study was applied to the real water reservoir, in the Morava River Basin. The result will be whether the dam is resistant to the current conditions, or the optimal design of the functional volumes of reservoir under conditions uncertainties.

Estimation of the Sediment Balance in the Selected Hydrometric Profile
Priesner, Radek ; Paseka, Stanislav (referee) ; Marton, Daniel (advisor)
The aim of the bachelor thesis is to evaluate the balance of suspended sediment load, respectively undissolved substances carried in suspension in the selected hydrometric profile. The work also contains methodical instructions for measurement and subsequent evaluation of sediment load, based on the Austrian methodological manual Leitfaden zur Erfassung des Schwebstofftransportes (Habersack et al., 2017). The calculations will be used as a partial basis for the project ATCZ28 SEDECO – Sediments, ecosystem services and interrelation with floods and droughts in the AT-CZ border region. The practical application will be implemented on data measured in hydrometric profile Přibice on the River Jihlava where continuous measurement of suspended sediment load has been taking place since 2019.

Uncertainty of Measurement Estimation of Mean Monthly Flows Values of the Selected Hydrometric Station at the Svitava River Catchment Area
Paseka, Stanislav ; Janál,, Petr (referee) ; Marton, Daniel (advisor)
Currently, a sizes of the time series elements of average monthly flows uncertainty are not taken into account in more detail and it does not know the estimation of their sizes. The above mentioned fact could ultimately affected the design and operation of large open water reservoirs. This bachelor's thesis deals with the uncertainty of measurement estimation of the mean monthly flows which have derived in the measuring profile Prostřední Poříčí in the Křetínka river in the Svitava river basin. Evaluation is done using a measured values of water level stages and a stage-discharge relation curve. The basis for design of uncertainty affected stage-discharge curves and water lavel stages the Monte Carl method is used. The outcome values of random flows are further evaluated using the statistical methods in the form of the statistical characteristics and presented as uncertainties of mean monthly flows.

Revitalization of the Hradisko Small Water Reservoir in the Radslavice Cadastral Area
Mrázová, Iva ; Menšík, Pavel (referee) ; Paseka, Stanislav (advisor)
The main goal of this thesis is to introduce the topic of small water reservoirs as an important landscape element, which contributes not only to creation of ecological stability, but also improves the quality of water in the catchment area, the microclimate, as well as helps to increase the groundwater reserves. The thesis consists of two parts. The first part of the thesis is theoretical and offers a brief description of the small water reservoirs, along with their main function, structure, history, and factors affecting their condition and causing the lack of them in the Czech Republic. The second part is practical and focuses on a review and the current state of a small water reservoir Hradisko in Radslavice. This part also includes a suitable suggestion for a solution regarding this case. The thesis was prepared in cooperation with the former mayor of Pustiměř and residents of Zelená Hora and Radslavice.

Uncertainty Analysis of Hydrological and Operating Parameters on Water Management Analysis of Reservoir Storage Capacity
Paseka, Stanislav ; Menšík, Pavel (referee) ; Marton, Daniel (advisor)
The aim of the thesis is to introduce the concept of Monte Carlo method for incorporating the uncertainties into the all hydrological and operational data inputs, which are needed to design and operation of large open water reservoir. Incorporating uncertainties into data inputs during calculation of reservoir storage capacity, then the consequent active conservation storage capacity is loaded by uncertainties. In the same way the values of outflow water from reservoir and hydrological reliability are affected by these uncertainties as well. For these kind of calculations the reservoir simulation model has been used, which simulate behavior operation of reservoir and is able to evaluate the results of simulations and help to reduction risk of storage capacity failure, respectively reduction of water shortages during reservoirs operation during low water and dry periods.

Design of water reservoir for flood protection
Vláčil, Lukáš ; Holomek, Michal (referee) ; Paseka, Stanislav (advisor)
The aim of this thesis is to map an anti-flooding protection in locality Dobrá Voda near Hořice and to create suitable plan of a water retention reservoir. Retention reservoir works as a system for holding and transformation of flood wave and thus for dealing with floods. First part of this thesis covers general description of issues of floods, current legislature, anti-flooding measures and a description of flood wave transformation. Methods for determination of retention seepage of the reservoir are described in this part as well. Computer programmes (HEC-RAS, Transformwave) were used for the purpose of above mentioned determination. In the second part of this thesis the given locality is described including all the possible risks and plans of convenient anti-flooding measures. The results of appropriate software determinations are compared in this part of the thesis as well. A final plan of a suitable retention reservoir is based on the results of comparison.

Uncertainty estimation of reservoir storage capacity in first stage of design preparation
Oulehla, Pavel ; Paseka, Stanislav (referee) ; Marton, Daniel (advisor)
The aim of the bachelor thesis is the estimation of reservoir storage capacity uncertainty. The input uncertainty is defined by the inaccuracy of the altitude geographic data. Using the appropriate altitude measuring and the estimated errors of the measurement, the change in the area – volumes curves is described as weel as its value of uncertainty. Afterwords the storage capacity loaded by batymetric curves uncertainty is calculated. Furthermore the uncertainty of the reservoir filling height has been quantified. For these kind of calculations the reservoir simulation model has been used, Monte Carlo method, to generate random values of the batygraphic curve has been used too. Expression of uncertainties when calculating the storage capacity can help to reduction risk of storage capacity failure, respectively reduction of water shortages during reservoirs operations during critical dry periods.
