Impact of Teplice restoration on river basin runoff – preliminary results

As part of the project for the Ministry of the Environment of the Czech Republic dealing with the monitoring of the impact of nature­‑friendly measures on improving the hydrological regime of small river basins, the Teplice river basin in the White Carpathians has been observed. Monitoring has been taking place since 2018, the measures were implemented in 2020. Data are available for the time period before the measures were implemented and for the year 2021, on which it is possible to observe the impact of the implemented revitalization. The data show the fluctuation of the daily runoff from the river basin and its overall reduction, which is probably caused by increased evaporation from the newly formed water bodies and increased water infiltration into the underground zone. After evaluating the observed data, there was a visible reduction in the surface runoff from the basin, which may nevertheless also be caused by the low rainfall totals in 2021.
