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.
Variability of water regime in forested experimental basis
Buchtele, Josef ; Tesař, Miroslav
Climatic conditions represent a significant factor for water regime of a watershed. They form conditions both for the vegetation cover development in the annual cycle and also its changes in the span of decades of years. Land-use changes can be a reason of variability and/or tendencies in the evapotranspiration process affecting water balance in both short-term and long-term temporal scales. The present contribution deals with simulations of the rainfall-runoff process with the help of SAC-SMA (Sacramento Soil Moisture Accounting) a BROOK´90 models. The time course of differences between observed and simulated runoff represents a possible tool for the evaluation of tendency and/or variability of water regime of a basin. The used approach makes possible to assess a result of long-term development of the vegetation cover in a catchment and consequent evapotranspiration changes.
