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.

Water loss by evaporation from free water surface

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.

HAMR: Online drought management system – operational management during a dry episode

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.

Determination of minimum residual flow values in the Czech Republic

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.

Hydrological balance and available water resource in the czech republic during hydrological drought

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.

Regionalization of deficit runoff volumes in the Czech Republic

The aim of the study is the regionalization of the Czech Republic with respect to drought characteristics in individual catchments.

Warning system for the Prague water system against micro-pollutant pollution

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.

Recent developments of the BILAN model

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.

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.
