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.

Drought in the Upper Metuje Basin in 2014–2019

Jan Kašpárek – 4/2021

In the years 2014–2019, there was a historic drought in the Czech Republic. The Department of Hydrology and Hydrogeology of the T. G. Masaryk Water Research Institute has been carrying out long-term hydrological and hydrogeological observations in the upper Metuje basin where this drought manifested itself significantly. The upper part of the catchment area of the Metuje River is located in the Police Cretaceous basin geological formation.

Professional seminar The impact of hydrological drought in 2015 on surface water quality

Ing. Tomáš Mičaník, Ph.D. – 6/2016

Almost the entire 2015 precipitation was below normal and on the contrary temperature significantly above normal. Precipitation deficit began to show early in 2015 and peaked in mid-August with a further deepening in the autumn months.

Hydrological groundwater drought

Ing. Eva Soukalová, CSc. and Ing. Radomír Muzikář, CSc. – 4–5/2015

The paper deals with the regularities of groundwater circulation with respect to extremely low groundwater level occurrence, seasonal and multiannual periodicity and trends of groundwater levels, occurrence of minimal levels and their impact on the enviromental components, methods of groundwater levels forecasts.

Interview with the Minister of the Environment Mgr. Richard Brabec on the topic of drought

Redakce – 4–5/2015

Drought has been and certainly will be. On this topic is based conversation with the Minister of the Environment, which includes questions on the continuing heat wave and drought.

Establishment and operation of the interdepartmental commission WATER-DROUGHT

RNDr. Tomáš Hrdinka, Ph.D. – 4–5/2015

Since the mid-80s of the 20th century in the Czech Republic is a demonstrable increase in water temperature slightly influenced by surface water as a result of climate change.
