From July 2023 VUHU a.s, together with scientific teams from several European countries, has participated as part of the EU research program in the solution of the REECOL project, which deals with the reclamation of areas affected by mining in European coal basins. One of the important tasks of the first phase of the project solution is to identify suitable case study areas in each country of the project solution. The selection of these areas in the Most Basin (CZ) is the subject of this paper. The selection of case study areas was based on the results of long-term research. The main part of the paper contains the characteristics and localization of...

The article evaluates changes in the hydrogeological behaviour of groundwater in the immediate vicinity of Lake Medard in 2023. Hydrogeological conditions in the area have been mapped since 2008, when the pumping of mine water at the bottom of the quarry was stopped. The final level of the lake (400.0 m a.s.l.)) was reached in March 2017. Four observation boreholes (MPT13, HG14, SV52 and 60PA) were used to monitor the groundwater levels in the vicinity of the lake in 2023. The obtained measurement results illustrate the view of the hydrogeological conditions in the area that have occurred since the lake was filled. After the final level is reached...
