Potential of areas protected for surface water storage to mitigate the impacts of climate change on drinking water supply
In the Czech Republic, areas morphologically, geologically and hydrologically suitable for surface water storage to mitigate the adverse effects of floods and droughts are defined through the General Plan for Surface Water Accu-mulation Areas. In the context of climate change, these locations create potential for possible adaptation measures. This article describes the assessment of the potential of selected sites for water supply under climate change condi-tions by means of hydrological and water balance modelling.
Balance of groundwater resources and demands for human consumption during climate change conditions
This article presents the results of the assessment of the possible impact of climate change on groundwater abstraction for human consumption between 2041 and 2060.
The current version of the BILAN model
BILAN is a comprehensive conceptual model in a daily/monthly structure (the diagram is shown in Fig. 1), simulating the components of the hydrological balance in a basin. Although its development was started at TGM WRI at the beginning of 1990s, it is a model that is still used as a standard in the Czech Republic… Read more »
Preservation of drinking water demand from water reservoirs in climate change conditions
This study presents interim results of an evaluation of a potential climate change impact on the preservation of drinking water demand provided by water reservoirs in the timeframe of the year 2050. Hydrological and water sources and demands balance procedures have been applied, including modelling of the storage ability of water resources and water supply systems.

HAMR: online drought management system – web presentation to the public
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.
Environment for life program and projects solved in TGM WRI
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.
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.
