| Abstract | The term “meromixis” means that a lake contains a chemically different, deep water layer due to incomplete mixing over the year. Ten years ago, Boehrer and Schultze (2006) discussed the relevance of meromixis for pit lakes. More than 100 papers have been published on meromixis in pit lakes since 2006, suggesting an update. Newly published papers have dealt with the interaction of underground workings and ground-water within meromictic pit lakes, double diffusion and erosion of the chemocline, climatic influences on meromixis, biogeochemical processes and microbial ecology in the water column and sediments, and predictive modelling. Results of the monitoring of meromictic pit lakes improved the understanding of processes and allowed in some cases to prove results of earlier modeling. Experiences with the management of meromictic pit lakes were also published. Meromixis is not the common mixing regime in pit lakes. However, meromixis seems to occur more frequently in pit lakes than in natural lakes due to the shape of the basin of pit lakes and the occurrence of chemically different waters in the catchment of many pit lakes. Therefore, and because of the particular chances and risks related to meromixis, it is of particular relevance in pit lakes. Based on the findings of the last ten years, predictive modeling of future pit lakes and the management of existing meromictic pit lakes can be made much better today. This contribution gives a brief introduction to the phenomenon of meromixis in pit lakes, summarizes the findings from the last ten years and draws conclusions regarding the management and predictive modeling of meromixis in pit lakes. |
