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.
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.
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.
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.
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.
