Using of the soil arametrisation based on soil samples database in rainfall-runoff modelling
Němečková, Soňa ; Košková, Romana ; Hesse, C.
The soil data processing and the simulations of the hydrological cycle in the Malse river basin using a distributed hydrological model SWIM are described. The Malse basin is situated in the southern Bohemia and it is a part of the Elbe river basin. Two sets of soil parameters were derived, the first one according to the soil samples (of the soil types) in the Malse watershed and the second according to samples from the whole Elbe river basin. The runoff simulations were completed based on both sets of parameters as the sensitivity test of the SWIM model to the soil data.
Otázky spojené se spolehlivým určením věrohodných parametrů srážko-odtokového modelu z dlouhých datových řad
Buchtele, Josef ; Košková, Romana
The paper focuses on the issue of the credible identification of parameters of rainfall-runoff models taking into account the length of the calibration period. The benefits of the usage of the long-time observed data series during the model parameter determination have been analysed. The article deals with the uncertainties connected to evolution of the vegetation cover within the simulation of different runoff components.
The simulation of evapotranspiration in the Malse basin using hydrological model SWIM
Košková, Romana ; Němečková, Soňa
This paper presents possibility of simulation of hydrological quatities which are hardly measured, in this case actual evapotranspiration. The distributed hydrological model SWIM has been used. It was dependence of evapotraspiration on several geographical factors that was assessed to prove the simulations.
Climate change and engineering precaution in all-planetary scale
Kos, Z. ; Košková, Romana
All the fundamental analysis of climate resulted in prediction of the climate change. The main impact of greenhouse gases production of mankind will be global warming. The political negotiations against climate change organised up to now require regulation of greenhouse gases only. Actions like the Kyoto Protocol will not stop the increase of concentrations of greenhouse gases and further global warming. On the other hand, the methods of engineering the whole planet - geo-engineering - are capable to reduce the global temperature by engineering methods.
Case Study Elbe - a Part of the Project NeWater
Košková, Romana ; Krysanova, V. ; Hesse, C. ; Blažková, Š. ; Martinková, M. ; Němečková, Soňa
The central tenet of the NeWater project is a transition from currently prevailing regimes of river basin water management into more adaptive regimes in the future. NeWater identifies key typical elements of the current water management system and focuses its research on processes of transition of these elements to adaptive IWRM. The development of concepts and tool that guide an integrated analysis is the corner-stone of research activities in the NeWater project.
Analysis of water regimes in two experimental basins in Beskydy Hills
Buchtele, Josef ; Košková, Romana ; Jařabáč, M.
Rainfall-runoff simulations were carried out in two experimental catchments with the aim of evaluation of the outflow changes caused by the defforestation. Results showed apparent influence on outflow.
Changes of water regime due to land use change
Buchtele, Josef ; Buchtelová, Marie ; Košková, Romana
Tendencies in water regime resulting from land-use change represent an important and actual subject for research on global scale as well as urgent problem from the local viewpoint.The assessment of deforestation, urbanisation and intense farming effects on flood regime on local or regional scale represent an important and integral part of such intentions and projects. Gradual deforestation, then overgrowing of deforested areas with grass or reforestation of some parts of catchments indicate that the change of vegetation cover did not occur as an abrupt change, but often even random phenomena took place, such as damage in woods inflicted by bark beetle, etc. In order to compare consequences of all these phenomena in different natural conditions simulations in relatively undisturbed areas, i.e. in the Šumava Mts in southern Bohemia were incorporated into the studies. The Vltava catchment down the river to Lenora village and Otava catchment down to Modrava are used for such comparisons.
Results of a rainfall-runoff model used for simulations in selected sub-basins of the Czech par of the Elbe river
Buchtele, Josef ; Košková, Romana ; Fořtová, Magda
The simulations of rainfall-runoff processes were prepared for the selected sub-basins of the Czech Labe river. The tool used for simulations was rainfall-runoff model Sacramento developed by the National Weather Service River Forecast Center. The aim of the project was to ascertain the changes int the observed and simulated runoff series caused by the geomorphological and climate conditions, by the model sensitivity to input data and by the human activities as land cover and land-use changes.
Implementace hydrologických modelů SAC-SMA a HSPF v povodí Vltavy pro uzávěrový profil Lenora
Košková, Romana ; Buchtele, Josef ; Vološ, B. ; Fořtová, Magda
Research aim is the application of two different rainfall-runoff models to a specific basin and comparison of the results of rainfall-runoff simulations obtained both with and without respect to data spatial variability
