Stochastic Management of the Open Large Water Reservoir with Storage Function with Using a Genetic Algorithm
(IOP Publishing, 2016-09-05)Described models are used random forecasting period of flow line with different length. The length is shorter than 1 year. Forecasting period of flow line is transformed to line of managing discharges with same length as ... -
Black Carbon and Its Effect on Carbon Sequestration in Soil
(MDPI, 2021-11-09)The properties of black carbon (BC) are described very differently in the literature, even when determined by the same methodological procedure. To clarify this discrepancy, BC was investigated in the clay Cambisols of ... -
Fractionation of Soil Organic Matter into Labile and Stable Fractions
(MDPI, 2022-01-03)The present study aims to test and evaluate the efficiency of a new modified method of organic matter evaluation. It allows the assessment of the quality and quantity of the primary soil organic matter and the stable organic ... -
Possibilities of Using Neuro-Fuzzy Models for Post-Processing of Hydrological Forecasts
(MDPI, 2021-07-08)When issuing hydrological forecasts and warnings for individual profiles, the aim is to achieve the best possible results. Hydrological forecasts themselves are burdened by an error (uncertainty) at the inputs (precipitation ... -
Irrigation with Treated Wastewater as an Alternative Nutrient Source (for Crop): Numerical Simulation
(MDPI, 2021-09-29)From a global perspective, drought is a well-known manifestation of climate change. The search for alternative sources of water also brings uncertainties and risks, for example, in relation to wastewater irrigation. We ... -
Influence of landscape retention capacity upon flood processes in Jičínka river basin
(Mendel University Press, 2014-05-12)This paper describes the retention capacity of the river basin and its course during a flash flood. Retention capacity of the river basin was measured of balancing of precipitation fallen in the river basin and discharges ... -
Development and Changes in Characteristics of Infiltration and Retention Facilities for Transport Infrastructure and Paved Area Surface Run-off Treatment
(Palacký University in Olomouc, 2014-12-01)The paper presents the results of water quality monitoring of road and parking surface run-off, which was done in the city of Brno in 2008-2009 and 2013-2014. The main results of the effectiveness of retention and infiltration ... -
Changes of Soil Aggregate Stability as a Result of the Effect of Freeze-thaw Cycles
(Acta Universitatis Agriculturae et Silviculturae Mendelianae Brunensis, 2015-09-01)The objective of the present research was to assess the changes in soil erodibility during the non-vegetation period as one of the factors affecting the snowmelt erosion. The temperature fluctuation was simulated with the ... -
Stochastic Forecast of Flow Reservoir Behaviour
(Elsevier, 2015-09-07)The main advantage of stochastic forecasting of flow reservoir behaviour is the fan of a possible value, which deterministic methods of forecasting could not give us. Future development of random process is described well ... -
The Impact of the Uncertain Input Data of Multi-Purpose Reservoir Volumes under Hydrological Extremes
(MDPI, 2021-05-16)The topic of uncertainties in water management tasks is a very extensive and highly discussed one. It is generally based on the theory that uncertainties comprise epistemic uncertainty and aleatoric uncertainty. This work ... -
Spatio-temporal analysis of remotely sensed and hydrological model soil moisture in the small Jicinka River catchment in Czech Republic
(SCIENDO, 2021-01-26)The knowledge of spatio-temporal dynamics of soil moisture within the catchment is very important for rainfall-runoff modelling in flood forecasting In this study the comparison between remotely sensed soil moisture and ... -
