Presence of water reservoirs (fishponds) in the basin and their impact on water runoff volume and peak flows during rainfall-runoff events
MUCHNA, Radek
This bachelour thesis is focused on an affect of ponds during rainfall-runoff events. Distribution of the water is desribed and how it affects a landscape. It is also defined what hydrological cycle is, its division and description. The thesis also evaluates precipitation, more specifically it is focused on extreme rainfall, which causes floods. In the thesis is mentioned a history of formation of ponds for better understanding of this topic and its context. This part deals with basic features and function of ponds, where to properly place them and their technical specification. The second part of the thesis begins with description of retention (a retention space) and accumulation (an accumulation space) and continues with recommondations for elevating the retention space in ponds. Then the thesis is focused on factors that more or less affect water runoff from a watershed. The main part of the thesis deals with the impact of water tanks on the size and shape of the hydrograph in rainfall-runoff events and it vividly demonstrates the affects of the ponds whether positive or negative on various floods in history of the Czech Republic.

The small reservoirs as part of cultural landscape
Portová, Nikola ; Vrba, Ing Jan (referee) ; Milerski, Rudolf (advisor)
While the title of this thesis is “Small reservoirs as a part of the cultural landscape”, the focus of this study is much broader. The analysis goes beyond small water reservoirs, discussing both the historical and technical aspects of their restoration with emphasis on the south Moravian reservoir systems. The opening chapter explores the history of the relationship water has with both society and nature. In the second chapter, the focus shifts onto the various roles, the physical and technical characteristics, as well as the methods for restoring small water reservoirs. In the final chapter, the emphasis shifts from reservoirs to ponds - and their utilization for farming fish. This chapter starts by exploring the current pond systems across Czech Republic, and then compares today’s south Moravian pond systems to their historical beginnings.

Managerial Evaluation of the Preparation for Construction of the Pond
Hronová, Monika ; Syrovátka, Oldřich (advisor) ; Žižka, Martin (referee)
The thesis disserts the decision making during the construction of a pond as water management source mainly focused on pre-implementation phase and the associated financial costs, from the decision of investor (builder), through appropriate site selection, to project preparation and selection of the contractor. The thesis marginally mentions the realization of the construction in terms of financial costs. In the practical part of the thesis, there is simplified procedure for pre-implementation phase, qualified estimate of the financial costs and the thesis also focuses on the selection of contractors and conditions that are related to the selection. The main contributions of the thesis is to introduce the issue of water management pre-implementation phase of construction of a pond, the procedure and conditions for decision to build a pond by the investor or hired individuals by the investor. Another practical part presents the percentage appreciation of the construction as a whole, which is divided into the costs associated with the appropriate site selection, project documentation, as well as costs associated with the purchasing of land and the cost of the construction itself. The results of this analysis showed that the avarage financial cost of 1 ha are 1,93 mil CZK. The main finding is that under these financial information is not easy to decide, because even two ponds with the acreage of 3,5 ha could have different budget, depending on the different local conditions. The guiding elements are particularly choice and suitability of the site for the construction. The final finding is, that the financial budget of the whole construction is divided into several parts. The part of pre-implementation, where is included the costs of site selection, land purchasing and project documentation, which is 9,4% of the total cost. The remaining 90,6 % of the cost is spent on the construction, which, based on the financial analysis, is the most costly.
