We applied a two-dimensional hydrodynamic model to explore the response of the thermal structure in Germany's largest drinking water reservoir, Rappbode Reservoir, to future climate projections and different water withdrawal strategies. We used projections for representative concentration pathways (RCP) 2.6, 6.0 and 8.5 from an ensemble of 4 different global climate models. Simulation results showed that epilimnetic water temperatures in the reservoir strongly increased under all three climate scenarios. Hypolimnetic temperatures remained rather constant under RCP 2.6 and RCP 6.0 but increased markedly under RCP 8.5. Under the intense warming in RCP 8.5, hypolimnion temperatures were projected to rise from 5 °C to 8 °C by the end of the century. Stratification in the reservoir was projected to be more stable under RCP 6.0 and RCP 8.5, but did not show significant changes under RCP 2.6. Similar results were found with respect to the light intensity within the mixed-layer. Moreover, the results suggested that surface withdrawal can be an effective adaptation strategy under strong climate warming (RCP 8.5) to reduce surface warming and avoid hypolimnetic warming. This study documents how global scale climate projections can be translated into site-specific climate impacts to derive adaptation strategies for reservoir operation. Moreover, our results illustrate that the most intense warming scenario, i.e. RCP 8.5, demands far-reaching climate adaptation while the mitigation scenario (RCP 2.6) does not require adaptation of reservoir management before 2100."}],"publication_identifier":{"issn":["0048-9697"],"eissn":["1879-1026"]},"author":[{"full_name":"Mi, Chenxi","last_name":"Mi","first_name":"Chenxi"},{"orcid":"0000-0002-4520-7916","full_name":"Shatwell, Tom","last_name":"Shatwell","id":"86424","first_name":"Tom"},{"first_name":"Jun","full_name":"Ma, Jun","last_name":"Ma"},{"first_name":"Yaqian","full_name":"Xu, Yaqian","last_name":"Xu"},{"full_name":"Su, Fangli","last_name":"Su","first_name":"Fangli"},{"first_name":"Karsten","full_name":"Rinke, Karsten","last_name":"Rinke"}],"intvolume":"       748","publication_status":"published","volume":748,"language":[{"iso":"eng"}],"date_created":"2024-12-08T20:23:26Z","citation":{"ieee":"C.

Thus, we simulated the metalimnetic oxygen minimum (MOM) in the Rappbode Reservoir with a well-established two-dimensional water quality model (CE-QUAL-W2) to systematically quantify the chain of events leading to its formation. We used high-resolution measured data to calibrate the model, which accurately reproduced the physical (e.g. water level and water temperature), biogeochemical (e.g. nutrient and oxygen dynamics) and ecological (e.g. algal community dynamics) features of the reservoir, particularly the spatial and temporal extent of the MOM. The results indicated that around 60% of the total oxygen consumption rate in the MOM layer originated from benthic processes whereas the remainder originated from pelagic processes. The occurrence of the cyanobacterium Planktothrix rubescens in the metalimnion delayed and slightly weakened the MOM through photosynthesis, although its decaying biomass ultimately induced the MOM. Our research also confirmed the decisive role of water temperature in the formation of the MOM since the water temperatures, and thus benthic and pelagic oxygen consumption rates, were higher in the metalimnion than in the hypolimnion. Our model is not only providing novel conclusions about the drivers of MOM development and their quantitative contributions, it is also a new tool for understanding and predicting ecological and biogeochemical water quality dynamics.","lang":"eng"}],"keyword":["Rappbode reservoir","CE-QUAL-W2","Planktothrix rubescens","Metalimnion","Oxygen consumption","Benthic processes"],"extern":"1","publication_status":"published","volume":175,"date_created":"2024-12-08T20:26:00Z","language":[{"iso":"eng"}],"citation":{"din1505-2-1":"<span style=\"font-variant:small-caps;\">Mi, Chenxi</span> ; <span style=\"font-variant:small-caps;\">Shatwell, Tom</span> ; <span style=\"font-variant:small-caps;\">Ma, Jun</span> ; <span style=\"font-variant:small-caps;\">Wentzky, Valerie Carolin</span> ; <span style=\"font-variant:small-caps;\">Boehrer, Bertram</span> ; <span style=\"font-variant:small-caps;\">Xu, Yaqian</span> ; <span style=\"font-variant:small-caps;\">Rinke, Karsten</span>: The formation of a metalimnetic oxygen minimum exemplifies how ecosystem dynamics shape biogeochemical processes: A modelling study.
