A Water Management Analysis of the Rychtářov Reservoir Protection Function
Fliega, Adam ; Sobek, Martin (referee) ; Menšík, Pavel (advisor)
The aim of this thesis is water management analysis of the protective function of the Ryhtářov water reservoir on the Velká Haná. Thesis contains hydrological model of the basin wich is compile in HEC-HMS program. According to this model are derive flood waves PV 100, PV 1000 a PV 10 000. Within of the protective function are designed outlets and spillway. The protective function is compile in HEC-HMS program, where calculations of transformation of derived flood waves are performed. The solution provides two different variants. These variants are compared at the work.

Lumped Water Balance Rainfall-Runoff Model Within a Daily Computational Time Step
Bednář, Martin ; Marton, Daniel
This paper aims to show the developed software representing a lumped water balance rainfall-runoff hydrological model. The software allows the user to create a simulation model of the rainfall-runoff process in any catchment for which the user can provide the necessary measured climatological and hydrological data. The calibrated model then can be used to predict runoff from the catchment based on the predicted input data, allowing for some analysis of the impact of climate change on hydrological conditions in the landscape. The model is developed and tested on a part of the Thaya river catchment, the part above the Vranov reservoir.

The assessment of change in the water balance of Hačka catchment due to the climate change
Moravec, Vojtěch ; Hanel, Martin (advisor) ; Ladislav, Ladislav (referee)
In the presented paper the changes in mean runoff, temperature and precipitation totals in
an observed period 1962-2015 in the catchment river Hačka are assessed. The paper further
presents the analysis of climate change impact on mean runoff between the periods 1984-2014
(control period) and 2035-2065 and 2068-2098 (scenario periods) using the projections of three
regional climate model simulations. Thin Plate Spline interpolation was used to estimate basin
precipitation and temperature. Modified hydrological analogy was used for precise quantification
of naturalized runoff (i.e. not affected by water use). Climate change scenarios were
derived using simple delta change approach, i.e. observed series of precipitation and temperature
were adjusted in order to give the same changes between the control and scenario period
as regional climate model simulations. Hydrological balance was modelled with a conceptual
hydrological model Bilan. The parameters of the hydrological model were estimated using observed
data. These parameters were subsequently used to derive discharge series under climate
change conditions for each regional climate model simulation. Results showed a 1.7 °C average
increase in mean annual temperature in the scenario period 2035-2065 and a 2.8 °C average
increase in the scenario period 2068-2098. The seasonal cycle of precipitation in the scenario
conditions is shifted, although mean annual precipitation totals remain practically unchanged
(max changes -8.1 %; +9.3 %). The mean annual discharge decreases by 5.7% in average (most
20.3 %) in period 2035-2065 and a significant decrease of 25.5% in average (most 45.9 %) in
annual mean discharge is expected in the period 2068-2098. Frequency of minimal runoff is expected
to increase up to two times. Precipitation increase is expected from the beginning of the
fall to the beginning of the summer, with a slight decrease in spring. Increase in precipitation
is followed by evapotranspiration increase, caused by increase in temperature. Summer precipitation
is expected to decrease as well as summer runoff. Due to the temperature increase, time
shift of the snowmelt is expected from the periods between March-April to January-February.
This will also affect the increase of the discharge in this period. This knowledge can be applied
in water management planning in the future.

Design of small water reservoir in cadastral area Volenice
Harnisch, Karel ; Havlíček, Vojtěch (advisor) ; Jan, Jan (referee)
The theme of this diploma theses is project of the small water reservoir on Mačický brook in cadastral Volenice. Water reservoir is designed mainly for the accumulation function, Water reservoir can improve water flow in the catchment area behind reservoir.
In the first part of this thesis is the literature searches which process the topic of the climate changes. Designed reservoir can work as a measure for mitigation one of the consequences of climate change drought. Further this section dealt with possibilities of design of all required elements for project of water reservoir.
The second part is focused on the very characteristics of the selected area which are used as base for the design.
The third part dealt with the design of the required individual objects for proper operation of the reservoir and their verification by using hydrotechnical calculations and flood wave transformation. Also is specified the design of the integration of the reservoir into the countryside by using riparian vegetation.

Vyhodnocení retenčního potenciálu vybraného povodí
Trávničková, Mirka
This thesis evaluates the potential retention in the catchment area of the Barchov brook, in its components parts. For identifying and evaluating hydrological characteristic, it was first necessary to mapping the area in terms landscape cover, topography terrain, soil properties and divided it into individual sub-basin. This data was processed in the ArcGIS version 10.0. The output of which were characteristics for each sub-basin such as: the length of the stream, the slope of the stream, size area, slope area, 1-day maximum rainfall amount, surface roughness and runoff curve number CN, which entering into the hydrological model DesQ-MaxQ. The output of the model were hydrological characteristics of the river sub-basin with the values the size of the potential retention, the volume of runoff, percentage of the stored water, flood wave volume, time of concentration and maximum flow. When evaluating the individual hydrological characteristics were taken into account morphological, soil, landscape and vegetation properties of the specific sub-basin.
