Vyhodnocení základních hydrologických charakteristik vybraného povodí

Kundrátová, Klára January 2016 (has links)
The diploma thesis is focused on rainfall-runoff relations of Srní potok (stream) basin. The input data were processed in the ArcGIS software. There was used hydrological model DesQ-MAXQ to evaluate retention potential in Srní potok basin. The thesis includes literature overview dealing with a water retention in a landscape and describing basic hydrological characteristics (a potential retention in the basin, a water flow, a water outfall, the time of concentration, the volume of a flood wave). A practical part of the thesis describes a characteristic of the interested basin, a preparation and a processing of the input data. There is evaluated the retention potential and a drainage conditions in the Srni potok basin in the conclusion. The outputs from the DesQ-MAXQ hydrological model describing the hydrological characteristics of the basin were graphically presented by map outputs created in the ArcGIS software.

Analýza odtokových poměrů ve vybraném povodí

Dufek, Václav January 2018 (has links)
The diploma thesis analyzes and evaluates the drainage conditions together with the retention potential of the landscape in the parts of the Bělský potok basin, which is located in the south of the Pardubice Region. The theoretical part of the thesis contains the elaborated literary research on the basis of the study of the specialized literature mentioned on the given issue, and also the characterization of the selected river basin. The practical part includes processing of underlying materials and data preparation in ArcGIS 10.3.1 using the ArcMap, ArcCatalog and ArcToolbox integrated applications suite. Processed data are the input information for the calculation of hydrological characteristics by the DesQ-MAXQ model.The resulting calculated values of maximum flows, specific flows, potential retention in the basin, concentration time, amount of water retained for each sub-basin are presented in the form of map outputs.

Studie odtokových poměrů vybraného povodí pomocí hydrologického modelování

Gottwaldová, Petra January 2019 (has links)
The diploma thesis "Study of runoff conditions of selected river basin using hydrological modeling" deals with analysis of runoff conditions and retention abilities of the Kašnice stream basin in the Břeclav district. The theoretical part deals with the literature review of the issue and the characteristics of the selected drainage area. Obtained information about surface cover types, hydrologic soil groups and CN curves numbers were processed in ArcGIS. The outputs were then used as input for the DesQ-MAXQ hydrological model. The resulting values of specific flow, time of concentration, potential retention, water retention and direct runoff volumes are presented in the form of attached map outputs. The result of the work is the evaluation of runoff conditions of the given 4th order river basin.

Vliv uspořádání krajiny na erozní a odtokové poměry povodí / Influence of the landscape management on erosion and runoff conditions of the catchment

Hájek, Daniel January 2016 (has links)
Aim of this study is to evaluate the effects of landscape structure on soil erosion and runoff conditions of given area with help of digital elevation model and relevant GIS data. Analyses of soil erosion by water and runoff were processed for current conditions and several other variations. Based on this analyses and results was performed an evaluation of all model variations.

Vytvoření hydrologického modelu pro odvození maximálních odtoků z malých povodí / Creating a Hydrological Model to Determine Maximum Runoff from a Small Catchments

Hakl, Petr January 2020 (has links)
The aim of the thesis is to set a hydrology model based on existed methodology DesQ-MaxQ, which comes from "Designing flows from a very small catchments" established in 1989. The model is able to set a nearest meteorology station and his 24-hours rainfall depths for periods of repetition 2,5,10,20,50 and 100 years. Substitute rainfall depths are set by "reduction of 24-hours rainfall depths" methodology. According to hydraulic and hydrology conditions of catchment, duration of the critical rains for each period of repetition are set also peak flow rates and total runoffs from the catchment. Application can work in two modes - "one slope" and "two slopes". The second option also includes calculation of design duration for the model catchment and superposition of hydrograph. Application RainRunoff was develop in C# programming language with graphic user interface and option to exports hydrographs.
