However, studies of climate warming effects on lentic waters usually do not sufficiently account for a change in heat flux from the catchment through altered inflow temperature and discharge under climate change. This is particularly relevant for reservoirs, which are highly impacted by catchment hydrology and may be affected by upstream reservoirs or pre‐dams. This study explicitly quantified how the catchment and pre‐dams modify the thermal response of Rappbode Reservoir, Germany's largest drinking water reservoir system, to climate change. We established a catchment‐lake modeling chain in the main reservoir and its two pre‐dams utilizing the lake model GOTM, the catchment model mHM, and the stream temperature model Air2stream, forced by an ensemble of climate projections under RCP2.6 and 8.5 warming scenarios. Results exhibited a warming of 0.27/0.15°C decade<jats:sup>−1</jats:sup> for the surface/bottom temperatures of the main reservoir, with approximately 8%/24% of this warming attributed to the catchment warming, respectively. The catchment warming amplified the deep water warming more than at the surface, contrary to the atmospheric warming effect, and advanced stratification by about 1 week, while having a minor impact on stratification intensity. On the other hand, pre‐dams reduced the inflow temperature into the main reservoir in spring, and consequently lowered the hypolimnetic temperature and postponed stratification onset. This shielded the main reservoir from climate warming, although overall the contribution of pre‐dams was minimal. Altogether, our study highlights the importance of catchment alterations and seasonality when projecting reservoir warming, and provides insights into catchment‐reservoir coupling under climate change.","lang":"eng"}],"language":[{"iso":"eng"}],"type":"scientific_journal_article","article_number":"e2023WR036808","publication_identifier":{"issn":["0043-1397"],"eissn":["1944-7973"]},"user_id":"83781","publication":"  Water resources research : an AGU journal","date_updated":"2025-06-24T14:14:26Z","_id":"12853","place":"New York, NY","status":"public","author":[{"first_name":"Bo","last_name":"Gai","full_name":"Gai, Bo"},{"full_name":"Kumar, Rohini","last_name":"Kumar","first_name":"Rohini"},{"full_name":"Hüesker, Frank","last_name":"Hüesker","first_name":"Frank"},{"last_name":"Mi","first_name":"Chenxi","full_name":"Mi, Chenxi"},{"last_name":"Kong","first_name":"Xiangzhen","full_name":"Kong, Xiangzhen"},{"full_name":"Boehrer, Bertram","first_name":"Bertram","last_name":"Boehrer"},{"last_name":"Rinke","first_name":"Karsten","full_name":"Rinke, Karsten"},{"last_name":"Shatwell","first_name":"Tom","id":"86424","orcid":"0000-0002-4520-7916","full_name":"Shatwell, Tom"}],"date_created":"2025-04-24T06:22:35Z","keyword":["climate change","coupled catchment-lake model","thermal characteristics","drinking water reservoir management","GOTMstratification"],"volume":61,"intvolume":"        61","title":"Catchments Amplify Reservoir Thermal Response to Climate Warming","external_id":{"isi":["001390720200001"]},"publisher":"American Geophysical Union (AGU)","department":[{"_id":"DEP8000"},{"_id":"DEP8022"}]},{"_id":"12213","status":"public","place":"Ambleside ","date_created":"2024-12-08T19:40:16Z","author":[{"last_name":"Determann","first_name":"Maria","full_name":"Determann, Maria"},{"full_name":"Musolff, Andreas","last_name":"Musolff","first_name":"Andreas"},{"last_name":"Frassl","first_name":"Marieke A.","full_name":"Frassl, Marieke A."},{"full_name":"Rinke, Karsten","first_name":"Karsten","last_name":"Rinke"},{"orcid":"0000-0002-4520-7916","id":"86424","full_name":"Shatwell, Tom","first_name":"Tom","last_name":"Shatwell"}],"publication_identifier":{"eissn":["2044-205X"],"issn":["2044-2041"]},"type":"scientific_journal_article","publication":"Inland waters : journal of the International Society of Limnology","date_updated":"2024-12-11T13:57:10Z","quality_controlled":"1","user_id":"83781","publisher":"Freshwater Biological Association","title":"Nutrient retention in a small reservoir under changed variability of inflow nutrient concentration","department":[{"_id":"DEP8022"}],"page":"560-575","intvolume":"        13","extern":"1","volume":13,"keyword":["catchment–lake interaction","concentration variability","GOTM-WET","lake nutrient export","reservoir biogeochemistry"],"issue":"4","doi":"10.1080/20442041.2024.2305105","citation":{"havard":"M.

Their functioning is based on an interplay of hydrological and biogeochemical processes, rendering them vulnerable to climate change. Future changes in catchment characteristics are likely to alter the timing and magnitude of nutrient concentrations in discharge. This study investigated the impact of changing variability of nutrient concentrations on lake and reservoir dynamics. We examined intraannual nutrient retention and analyzed the role of reservoirs in reconfiguring the variability of nutrients. Utilizing the 1D lake model GOTM-WET, we simulated nutrient processing in a mesotrophic reservoir. Further, we performed scenario simulations by modifying the variability of inflow nitrogen and phosphorus concentrations. Our findings indicate that the reservoir removed ∼4% and ∼12% of total nitrogen (TN) and total phosphorus (TP), respectively. Particulate fractions were retained efficiently, but there was a net export of dissolved organic fractions. Regarding mixing and stratification periods, however, we observed net nitrogen export during stratification in certain years. During stratification, outflow concentration variability remained relatively unchanged for TN and TP compared to inflow concentrations. Conversely, phosphate and nitrate concentration variability increased in the outflow because of in-lake assimilation and the influence of hydrological events. With increasing inflow concentration variability during stratification, there was decreased removal of TN and TP by the reservoir, but increased variability of concentration. By evaluating the lake's capacity to attenuate variability of nutrient inflows under altered conditions, there are opportunities to improve monitoring of nutrient export and evaluate the potential impact of nutrient peaks on downstream drinking water resources and ecosystems.","lang":"eng"}]},{"abstract":[{"lang":"eng","text":"A precise understanding of the mechanisms causing phytoplankton blooms in reservoirs is still lacking, especially in large riverine reservoirs. To better understand these blooms, the role of the complex hydrodynamics caused by dam operation must be quantified. Here we examine how synergistic hydrodynamic processes, rather than individual metrics, trigger blooms in Xiangxi Bay, a typical tributary bay of the Three Gorges Reservoir, China. We used a 3D ecological-hydrodynamic model, which integrated hydrodynamics with the abiotic factors that limit phytoplankton growth to simulate one whole year (2010). By implementing a scaling criterion, we quantified the contribution of local phytoplankton growth and hydrodynamic processes, including advection transport and vertical mixing, on bloom dynamics. Results indicated vertical mixing was the main process inhibiting blooms in colder months (from October to February) but horizontal advection, which flushed and diluted blooms, was dominant in warmer months (from May to July) when stratification was intense and nutrients were replete. Accordingly, blooms occurred when both vertical mixing and horizontal advection were low. We suggested a potential dam operation strategy to mitigate blooms during stratification, which involves withdrawing the warm surface water from upstream reservoirs to increase horizontal flows in the surface layer. Extending the application of critical turbulence model, our study shows how vertical mixing and horizontal advection rate interact with phytoplankton growth rate to drive blooms in highly dynamic riverine systems."}],"publication_status":"published","language":[{"iso":"eng"}],"year":"2023","citation":{"van":"Gai B, Sun J, Lin B, Li Y, Mi C, Shatwell T.

Here, we tackled this issue by investigating a unique catchment-reservoir system with two reservoirs in distinct trophic states (meso‑ and eutrophic), both of which drain into the largest drinking water reservoir in Germany. Due to the prolonged droughts in 2015–2018, the catchment of the mesotrophic reservoir lost an unprecedented area of forest (exponential increase since 2015 and ca. 17.1% loss in 2020 alone). We coupled catchment nutrient exports (HYPE) and reservoir ecosystem dynamics (GOTM-WET) models using a process-based modeling approach. The coupled model was validated with datasets spanning periods of rapid deforestation, which makes our future projections highly robust. Results show that in a short-term time scale (by 2035), increasing nutrient flux from the catchment due to vast deforestation (80% loss) can turn the mesotrophic reservoir into a eutrophic state as its counterpart. Our results emphasize the more prominent impacts of deforestation than the direct impact of climate warming in impairment of water quality and ecological services to downstream aquatic ecosystems. Therefore, we propose to evaluate the impact of climate change on temperate reservoirs by incorporating a time scale-dependent context, highlighting the indirect impact of deforestation in the short-term scale. In the long-term scale (e.g. to 2100), a guiding hypothesis for future research may be that indirect effects (e.g., as mediated by catchment dynamics) are as important as the direct effects of climate warming on aquatic ecosystems.","lang":"eng"}],"_id":"12223","date_created":"2024-12-08T19:52:43Z","author":[{"full_name":"Kong, Xiangzhen","last_name":"Kong","first_name":"Xiangzhen"},{"last_name":"Ghaffar","first_name":"Salman","full_name":"Ghaffar, Salman"},{"full_name":"Determann, Maria","last_name":"Determann","first_name":"Maria"},{"last_name":"Friese","first_name":"Kurt","full_name":"Friese, Kurt"},{"last_name":"Jomaa","first_name":"Seifeddine","full_name":"Jomaa, Seifeddine"},{"last_name":"Mi","first_name":"Chenxi","full_name":"Mi, Chenxi"},{"last_name":"Shatwell","first_name":"Tom","full_name":"Shatwell, Tom","id":"86424","orcid":"0000-0002-4520-7916"},{"full_name":"Rinke, Karsten","first_name":"Karsten","last_name":"Rinke"},{"last_name":"Rode","first_name":"Michael","full_name":"Rode, Michael"}],"status":"public","place":"Amsterdam","publication_identifier":{"issn":["0043-1354"],"eissn":["1879-2448"]},"article_number":"118721","type":"scientific_journal_article","quality_controlled":"1","date_updated":"2024-12-11T13:11:19Z","publication":"Water research : a journal of the International Water Association","user_id":"83781","publisher":"Elsevier BV","title":"Reservoir water quality deterioration due to deforestation emphasizes the indirect effects of global change","department":[{"_id":"DEP8022"}],"extern":"1","intvolume":"       221","volume":221,"keyword":["Deforestation","Climate change","Temperate regions","Reservoir","Eutrophication","Process-based modeling"]},{"language":[{"iso":"eng"}],"publication_status":"published","abstract":[{"text":"The thermal structure in reservoirs affects the development of aquatic ecosystems, and can be substantially influenced by climate change and management strategies. 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.","lang":"eng"}],"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."}],"_id":"12235","main_file_link":[{"url":"https://doi.org/10.1016/j.watres.2020.115701"}],"date_created":"2024-12-08T20:26:00Z","author":[{"last_name":"Mi","first_name":"Chenxi","full_name":"Mi, Chenxi"},{"last_name":"Shatwell","first_name":"Tom","full_name":"Shatwell, Tom","id":"86424","orcid":"0000-0002-4520-7916"},{"full_name":"Ma, Jun","first_name":"Jun","last_name":"Ma"},{"first_name":"Valerie Carolin","last_name":"Wentzky","full_name":"Wentzky, Valerie Carolin"},{"full_name":"Boehrer, Bertram","last_name":"Boehrer","first_name":"Bertram"},{"first_name":"Yaqian","last_name":"Xu","full_name":"Xu, Yaqian"},{"first_name":"Karsten","last_name":"Rinke","full_name":"Rinke, Karsten"}],"place":"Amsterdam","status":"public","publication_identifier":{"eissn":["1879-2448"],"issn":["0043-1354"]},"article_number":"115701","type":"scientific_journal_article","quality_controlled":"1","publication":"Water research : a journal of the International Water Association","date_updated":"2024-12-09T10:25:49Z","user_id":"83781","publisher":"Elsevier BV","title":"The formation of a metalimnetic oxygen minimum exemplifies how ecosystem dynamics shape biogeochemical processes: A modelling study","department":[{"_id":"DEP8022"}],"intvolume":"       175","extern":"1","keyword":["Rappbode reservoir","CE-QUAL-W2","Planktothrix rubescens","Metalimnion","Oxygen consumption","Benthic processes"],"volume":175}]
