Souhrn V poslední době se velmi diskutuje – a to nejen mezi odbornou veřejností – o dopadech změny klimatu na vodní režim v přírodní krajině. Řešení OP Praha – pól růstu se zaměřilo i na krajinu kulturní v bezprostřední blízkosti města… Read more »
Drought and water shortages are concepts that need to be spaced properly differentiate. Drought is a temporary decrease in water availability and is considered a natural phenomenon. Drought is characterized by its gradual onset, considerable area and long duration.
Environmental protection is one of the important societal needs. Appropriately oriented applied research is also necessary for its fulfillment.
Update of empirical relationships for calculation of free water surface evaporation based on observation at Hlasivo station
Evaporation from free water surface is one of the essential components of water circulation in nature and significantly affects the overall water balance of the catchment. Due to the complicated direct measurement, it is often calculated from formulas that require available meteorological variables as input data.
Evaporation from free water surface is one of the important factors affecting the total water balance of a catchment. Since direct measurement of evaporation is complicated, evaporation is in practice often calculated using formulas based on common meteorological variables.
Increasing occurrence of drought periods in the Czech Republic has highlighted a necessity of legislation modification. At the same time, a need has emerged for tools supporting decision making and water resources management at various levels during the drought periods.
Study on the assessment of the effect of nature-friendly measures in the Olešná in Pelhřimov catchment area using the BILAN, HEC-HMS and HYPE models
A catalogue of natural restoration measures was created within several research programs under Ministry of the Environment of the Czech Republic, especially in the program for hydrological draught mitigation. As a next step suitable catchments for their application were identified. With use of hydrological models, the effect of designed restoration measures on three aspects of hydrological regime was assessed.
Article is based on the amendment to Act no. 254/2001 Coll. pursuant to the wording of Act no. 150/2010 Coll., the Ministry of Environment has been charged with the task of drafting a Government regulation on the method and criteria for determining the minimum residual discharge values.
The article deals with the assessment of the hydrological balance in a monthly time step in the territory of the Czech Republic, which was divided into 133 sub-basins for the period 1981–2015.
The aim of the study is the regionalization of the Czech Republic with respect to drought characteristics in individual catchments.
Physicians with a little exaggeration claim that a healthy person does not exist, only to be met with a poorly-diagnosed patient. This claim can also be applied to drinking water and wastewater.
Possible compensation of negative climate change impacts using the localities for potential accumulation of surface water
The list of localities potentially suitable for accumulation of surface water (LASW) exists in the Czech Republic from the beginning of 20th century.
The BILAN model has been used in a number of research projects and hydrological studies dealing with estimation of water balance for European catchments. This paper is focused on the recent development of the model during last years. The model changes include both core development (new variables representing water use, optional calibration for a system of catchments, saving of state variables) and enhanced user interface that was extended by new graphical outputs and controls allowing interactive use of the model.
