Droughts and floods are extreme hydrological phenomena that are currently increasing in frequency due to the growing impact of climate change, and can have significant effects on our lives. Within the “PERUN” research project, an assessment of drought conditions and their development in the Czech Republic is being developed, along with the innovation of the warning system by the Czech Hydrometeorological Institute (CHMI). Drought is a natural phenomenon characterized by a gradual onset, long duration, and low dynamics, which requires a specific approach. The amendment to the Water Act introduces the obligation of regular reporting on drought and the establishment of a predictive service to be conducted by CHMI. Tools are being developed for long-term prediction of water resource conditions and a methodology for drought and water scarcity management plans. These plans aim to ensure water supply, protect the environment, and minimize the economic impacts. The decision-making body for issuing measures based on the drought plans is the Drought Commission, which operates at the regional level. The warning information is available on the HAMR web portal, which also displays local threshold limits for individual water resources.

Preservation of drinking water demand from water reservoirs in climate change conditions

Ing. Adam Vizina, Ph.D., Ing. Petr Vyskoč, Ing. Martina Peláková, Ing. Jiří Picek, Ing. Adam Beran, Ph.D. and Ing. Roman Kožín – 3/2021

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.

Impact of drought and water scarcity on water use assessment

Ing. Petr Vyskoč, RNDr. Hana Prchalová and Ing. Jiří Dlabal – 4/2017

Exist tools for water balance, time series of water abstractions and their season variability, difference between permitted and real abstractions and impact of drought in 2015 were analysed and assessed in subtask Impact of Drought on Water Use Assessment.

Policy of Protection from impacts of drought and water scarcity in the Czech Republic – consultation and processing

RNDr. Tomáš Hrdinka, Ph.D., Ing. Magdalena Nesládková, Ing. Tereza Davidová, Ph.D. and RNDr. Pavel Punčochář, CSc. – 4/2017

In the context of a severe drought period, which has started in 2014, an inter-ministerial commission WATER-DROUGHT was established to prepare a strategic policy document on protection from impacts of drought and water scarcity in the Czech Republic.

The drought management plan in the Czech Republic

Ing. Radek Vlnas – 4/2017

The paper presents the preparatory phase of the draft of the drought management plan in the Czech Republic in the commenting process. The plan is a basic document of drought protection.

Application of the water unavailability factor for characterisation of water use in LCA studies in the Czech Republic

Ing. Libor Ansorge, Ph.D. – 6/2016

The following article summarises the results of testing a method for the characterisation of water use in the system of life cycle assessment in the Czech Republic. The chosen method allows for robust expression of water use in the equivalent values of the reference system.
