Lorencová, Eliška ; Emmer, Adam ; Geletič, Jan ; Bašta, Petr ; Vačkář, David
Climate change is one of the key challenges of the 21st century, both in terms of adaptation as well as mitigation. The aim of this research was, following the Adaptation Strategy of the City of Prague, to prepare the background analysis for the Adaptation Action Plan, focusing on vulnerability assessment. The vulnerability asssessment focused on the climate change impacts related to: (i) temperature extremes - heatwaves, (ii) insufficient rainwater retention and extreme rainfall. The approach included spatially-specific analysis using ArcGIS based on climatic, land use and socio-economic indicators for the current status and future RCP 4.5 and RCP 8.5 scenarios. Regarding vulnerability to heatwaves, the most affected areas are located in the city center (Prague 2, Prague 3, Prague 6, Prague 7, Prague 1) and some peripheral areas with industrial buildings (e.g. Libeň or Štěrboholy). Vulnerability to extreme precipitation and insufficient rainwater retention was highest particularly at the confluence of the Vltava and Berounka (Velká Chuchle, Prague 16, Zbraslav and Lipence).
Influence of landscape type surrounding the roads towards the frequency of traffic accidents in Písek region
Necid, Pavel ; Bašta, Petr (advisor) ; Gdulová, Kateřina (referee)
Bachelor thesis aimed on analysis of car Accidents in the area of MEC Pisek in relation to the landscape. Database of car accidents within years 2007 - 2013 was analyzed as well as the basic terrain parameters.The results show high complexity and interconnection between all factors. The results of simple database analysis show, that there is higher risk of car accident on Monday and Sunday, as well as highest risk of drink drive offence on Saturday. Elevation and slope of the terrain does not play any major role. There is also no reason for fear from driving in the forest. For detailed analysis, much more complex data are needed.
Analysis of the water network development and utilization of water resources in and around Hradec Králové
Barborik, Lukáš ; Gdulová, Kateřina (advisor) ; Bašta, Petr (referee)
This thesis analyzes the use of water resources, development of water supply and water management structures since the 60s of the 20th century to the present day. Background materials provided on request by Vodovody a kanalizace Hradec Králové a.s. from their archives. The materials consist of text and map outputs from master plans of water supply network. For the analysis were created maps of water network in the years 1973, 1981, 1994 and 2010, whose underlying maps are digitized material from the period. As graphical output was used ArcMap program. The analysis assesses the development and future of drinking water resources, water network and water management structures and can serve as a starting point for a more detailed examination of historical events and developments in and around Hradec Králové.
The comparison of digital terrain model sources in GIS for hydrological purposes
Klempíř, Hynek ; Bašta, Petr (advisor) ; Gdulová, Kateřina (referee)
This thesis deals with comparsion of digital terrain models from different sources processed in GIS for hydrological purposes. The diploma thesis is composed from several parts. First part sis consist of characteristics related to watershed and water flow, which are important for the understanding this work. The thesis also describes digitial terrain model, his creation and methods for obtainig digitial models. Then, there are described data sources from which is possible to gain digitial models. Next chapter is dedicated to the coordinate system. The last parts of this thesis describes drain alghorithms. Characteristic of this area was collected on experimental watershed Modrava II with the ESRI ArcGIS Desktop software that would mainly Spatial Analyst and ArcHydro extensions. The results of this diploma thesis can be concluded that the free digital terrain model SRTM 90 is not suitable for small regions with diverse terrain structure. Thereason is a small resolution model. Other terrain models provided free of chargé are sufficient even for small areas as the selected area of interest. Paid digitial models can al lbe established for the area of interest as appropriate.

Then Bachelor thesis suggests to provision their saving, resousces of saving Děčín´s thermal structure, but the same some possibilities of their progress. The result of bachelor thesis will be not only propose actions to save the Děčín´s thermal structure, but find possibilities other wastes to Děčín and enviroment as well.
Derivation of rating curve for discharge estimation in the centre of Prague
Fojtová, Tereza ; Pavlásek, Jiří (advisor) ; Bašta, Petr (referee)
This thesis deals with the processing of data of water levels and flow measurements in measuring profile Vltava at Charles Bridge in Prague. The work is divided into theoretical part, ie. literature search and the practical part. Review of literature deals with the characteristics of the Vltava River, the basic hydrological concepts. For the most part it focuses on the importance hydrometry or the science of water, which thoroughly explains how the water levels and flow rates are measured and how measurement methods can be used. The practical part describes the characteristics of the territory and processing measured values, which were measured at three different points in time. They referred to the resulting data are shown in the tables and plotted in the graphs. Finally, the work was compiled empirical density curve, which graphically illustrates the relationship between the water level and flow. To curve the optimum, we have chosen various processing procedures.
The Bathymetry of Němčice reservoir
Prchal, Jan ; Máca, Petr (advisor) ; Bašta, Petr (referee)
Bathymetric measurements are important for mapping relief of current reservoirs and streams. Due to the lack of similar measurements in the Czech Republic is presented diploma thesis focused on the implementation of the first bathymetric survey on the water reservoir located on the basin Němčice - Sedlický stream. As a part of the work was done bathymetric data collection device River Surveyor M9 data processing interpolation procedures and evaluate the mutual comparison of estimation results. It was also evaluated the effect of the resolution to the retention volume of the tank and its sedimentations regime. Based on the evaluation of the measurement is based on a minimum average error method Universal Kriging. Processed data were measured during the year 2015. The result of the work can serve as a guide for subsequent measurements and estimates bathymetric data on a similar small reservoirs in the catchment areas of the Czech Republic.

Strnad, David ; Gdulová, Kateřina (advisor) ; Bašta, Petr (referee)
This theses reports on facts about pumped storage power plants. The first part of the theses introduces us to the importace of hydropower, consists of a description of historical development of pumping sets, and also defines limitations for its potential suitable localization. The research is processed via ArcGIS software and it´s methodologically divided into three phases. The first phase is searching for the minimum suitable terrain gradient on the whole Czech landscape and it defines local insterests for the next phase of research. The second phase is based on limited factors and assesses the chosen location of interest. The final phase provides detail on the most potentially suitable destinations with specific locations of pumped storage power plants. The study resulted in map outputs of final destinations and locations of interest across the Czech landscape. The distinction of source data and the importace of classification of enviromental factors are included in the discussion.
Analysis of flood protection measure on Cehnický potok – dry polder
Předota, Michal ; Bašta, Petr (advisor) ; Vokoun, Martin (referee)
This bachelor thesis aims on flood troubleshooting and on the flood protection Czech Republic uses. The theoretical part sums up the flood proces - its origin, process and types of flood. It describes the management of flood protection system and all means of flood protection. It contains a detailed description of dry polders, which represent a protective and retention function in the countryside. Further on it defines the concept of river flow, flood wave, active flood zone, degree of flood activity and small water reservoir. The practical part contains a characteristic of the area of interest of flow polder of the Cehnice village, through which flows the Cehnice stream. The efficiency and functionality of this polder has not been sufficiently verified yet and so the main benefit of this thesis is the calculation of transformation of the flood wave by the dry polder of Cehnice with the period of repeatability Q100, Q50 and Q20 using "numerical method for dry reservoir assessment", evaluation of the results and an analysis of the current flood situation in the area of Cehnice village.
