Abstract The conceptual SACRAMENTO soil moisture accounting model and the physically based forest hydrological BROOK have been used in runoff simulations for small medium sized basins with aim of investigating contributions different components to overall runoff. seem confirm results previous experiments environmental tracers which prevailing groundwater reported.

Natural variability, i. e. climatic oscillation, influences the development of vegetation in annual cycle. At same time it creates conditions for changes cover even scale centuries. This is phenomenon, which causes variation or tendencies evapotranspiration demands and consequently water storage regime, its long change sometimes disregarded. The simulation rainfall-runoff process has been used re-evaluation assumed demand due to developing groundwater catchments. simulations provide results,...

The water regime variability in most catchments is frequently influenced not only by the changes of vegetation cover annual cycle but also its development time span decades. That means that resulting evapotranspiration depends on actual climatic situation soil moisture. simulations rainfall-runoff process have been used with intention to follow possible role developing land cover. differences between observed and simulated flows relatively long periods can be considered as an appropriate...

Abstract Co‐pyrolysis of coal with waste polymers in a stationary quartz reactor was performed. Mass balance the process evaluated and properties products were characterized. The main product (solid carbonaceous residue) exhibits low ash sulfur contents and, from point view application, satisfactory surface properties. Therefore, solid residue is suitable as smokeless fuel or an industrial sorbent. by‐products tar gas. may be used source chemicals low‐sulfur heating oil, gas highly...

The influence of vast salvage clear cutting in some hilly regions induced by acid rains is sometimes considered as a significant contribution to the disastrous character recent floods. Then considerations having also partly emotional character, appeared, namely after large floods Morava and Odra Rivers July 1997 Labe River basins August 2002. simulations rainfall-runoff process for several experimental catchments have been carried out using daily time series up 50 years long. outputs...

Considerable long-term time series of precipitations and air temperature changes were used for modelling the rainfall-runoff process. The also accurate assessment evapotranspiration demand Czech Elbe River. Random fluctuations vegetation cover are taken as an indication deviations in evapotranspiration. intention is to appraise such complicated a recently modified software conceptual SAC-SMA model firstly enables prompt simulation secondly creates conditions automatic calibration this model....
