Quantifying and reducing external nutrient inputs in these systems remains a significant challenge. The difficulty arises from low monitoring frequencies of the highly dynamic external inputs and the limited availability of measures to reduce diffuse source loading. One option for the latter is the use of pre-dams, i.e. small impoundments at the inflow points into reservoirs, designed to retain nutrients by algal uptake and sedimentation. This study analyzes long-term (ranging from 8 to 22 years) nutrient and discharge time series for nine German pre-dams to assess their retention capacity. For that, we (i) quantified nutrient loading using four different mathematical methods, (ii) derived their retention efficiencies, and (iii) identified environmental factors determining the retention of nitrogen (N), phosphorus (P), and silica (Si). We show that retention of soluble reactive phosphorus (SRP) (43.6 %) and total phosphorus (TP) (39.9 %) is far higher than for nitrate (NO3) (15.3 %) and Si (15.9 %). The retention efficiency for SRP and TP was higher during the warm seasons because of higher algal nutrient uptake and thus higher nutrient sedimentation. Mixed effects models documented a significant positive effect of the pre-dams' hydraulic residence time (HRT) on retention efficiency. Pre-dams provide substantial service in retaining nutrients and help to protect downstream waterbodies from nutrient inputs. They provide effective measures for trapping nutrients including those originating from non-point sources.","lang":"eng"}],"type":"scientific_journal_article","publisher":"Elsevier BV","external_id":{"pmid":["39647312"],"isi":["001377992000001"]},"doi":"10.1016/j.watres.2024.122864","date_updated":"2025-06-24T14:12:42Z"},{"issue":"8","quality_controlled":"1","date_updated":"2024-12-11T13:11:19Z","doi":"10.1016/j.watres.2022.118721","type":"scientific_journal_article","publisher":"Elsevier BV","keyword":["Deforestation","Climate change","Temperate regions","Reservoir","Eutrophication","Process-based modeling"],"extern":"1","abstract":[{"lang":"eng","text":"Deforestation is currently a widespread phenomenon and a growing environmental concern in the era of rapid climate change. In temperate regions, it is challenging to quantify the impacts of deforestation on the catchment dynamics and downstream aquatic ecosystems such as reservoirs and disentangle these from direct climate change impacts, let alone project future changes to inform management. 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."}],"department":[{"_id":"DEP8022"}],"user_id":"83781","year":"2022","status":"public","title":"Reservoir water quality deterioration due to deforestation emphasizes the indirect effects of global change","publication_identifier":{"eissn":["1879-2448"],"issn":["0043-1354"]},"author":[{"first_name":"Xiangzhen","last_name":"Kong","full_name":"Kong, Xiangzhen"},{"last_name":"Ghaffar","full_name":"Ghaffar, Salman","first_name":"Salman"},{"last_name":"Determann","full_name":"Determann, Maria","first_name":"Maria"},{"full_name":"Friese, Kurt","last_name":"Friese","first_name":"Kurt"},{"first_name":"Seifeddine","last_name":"Jomaa","full_name":"Jomaa, Seifeddine"},{"first_name":"Chenxi","full_name":"Mi, Chenxi","last_name":"Mi"},{"orcid":"0000-0002-4520-7916","first_name":"Tom","id":"86424","last_name":"Shatwell","full_name":"Shatwell, Tom"},{"last_name":"Rinke","full_name":"Rinke, Karsten","first_name":"Karsten"},{"first_name":"Michael","last_name":"Rode","full_name":"Rode, Michael"}],"intvolume":"       221","language":[{"iso":"eng"}],"date_created":"2024-12-08T19:52:43Z","volume":221,"publication_status":"published","place":"Amsterdam","citation":{"ama":"Kong X, Ghaffar S, Determann M, et al.

Rapid winter warming and increasing observations of winter blooms warrant more investigation of these controls. We investigated the mechanisms regulating a massive winter diatom bloom in a temperate lake. High frequency data and process-based lake modeling demonstrated that phytoplankton growth in winter was dually controlled by light and temperature, rather than by light alone. Water temperature played a further indirect role in initiating the bloom through ice-thaw, which increased light exposure. The bloom was ultimately terminated by silicon limitation and sedimentation. These mechanisms differ from those typically responsible for spring diatom blooms and contributed to the high peak biomass. Our findings show that phytoplankton growth in winter is more sensitive to temperature, and consequently to climate change, than previously assumed. This has implications for nutrient cycling and seasonal succession of lake phytoplankton communities. The present study exemplifies the strength in integrating data analysis with different temporal resolutions and lake modeling. The new lake ecological model serves as an effective tool in analyzing and predicting winter phytoplankton dynamics for temperate lakes."}],"extern":"1","keyword":["Winter diatom bloom","High frequency monitoring","Lake modeling","Light limitation","Temperature"],"status":"public","year":"2020","user_id":"83781","department":[{"_id":"DEP8022"}],"doi":"10.1016/j.watres.2020.116681","date_updated":"2024-12-09T11:24:12Z","quality_controlled":"1","publisher":"Elsevier BV","type":"scientific_journal_article","article_number":"116681","_id":"12231","publication":"Water research : a journal of the International Water Association","main_file_link":[{"url":"https://doi.org/10.1016/j.watres.2020.116681"}],"title":"Unravelling winter diatom blooms in temperate lakes using high frequency data and ecological modeling","place":"Amsterdam","citation":{"apa":"Kong, X., Seewald, M., Dadi, T., Friese, K., Mi, C., Boehrer, B., Schultze, M., Rinke, K., &#38; Shatwell, T.

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."}],"extern":"1","keyword":["Rappbode reservoir","CE-QUAL-W2","Planktothrix rubescens","Metalimnion","Oxygen consumption","Benthic processes"],"publisher":"Elsevier BV","type":"scientific_journal_article","doi":"10.1016/j.watres.2020.115701","date_updated":"2024-12-09T10:25:49Z","quality_controlled":"1","issue":"5"}]
