The over‐enrichment of water bodies by nutrients and the increase in primary production is a natural process that happens slowly, however, this process has been occurring in recent decades rapidly, due to the increase in the external load of anthropogenic nutrients, mainly phosphorus. Lake and reservoir eutrophication models seeking to calculate the critical load of phosphorus often do not consider the temporal variation in water volume. In this study, a dynamic model was used to estimate critical loads of phosphorus from six reservoirs in Brazil's semi‐arid region, all of which experience great water volume variation, to describe the variation in water balance together with the variation in phosphorus mass balance. The critical load of phosphorus was defined as the load that guaranteed total phosphorus concentrations of up to 30 mg/m3 throughout 90% of the simulation period. A total of 40 scenarios were simulated and combined two vertical flows of phosphorus, five concentrations of phosphorus in the affluent volumes, and four water demands. Results revealed that the critical load of phosphorus was strongly affected by water demand, what pose a strong dilemma toward the operation of reservoirs in the semi‐arid region of Brazil between rationing stored water for use in long periods of drought or stimulating water use to increase water turnover rates. The critical load of phosphorus was also affected by phosphorus concentration in affluent volumes, and the vertical flow of phosphorus between the sediment and water columns. The findings of this study can help for better understanding of the impact of temporal variations in lake and reservoir water volumes to define critical loads of phosphorus more accurately and control eutrophication more effectively in these environments.

“…According to the principle of material balance, the Vollenweider model was developed by the renowned Canadian scholar Vollenweider in 1968, precisely for the purpose of total phosphorus load balance in lakes. The specific equations of this model can be found in the literature (please refer to the cited sources) (Djelita et al, 2017; Vollenweider, 1975). This model assumes a steady state condition and calculates the concentration of phosphorus in the lake water.…”

Ecological models hold significant potential for advancing lake research. In this study, we employed CiteSpace, a bibliometric analysis tool, and VOSviewer, a visualisation software, to facilitate a comprehensive understanding of recent advancements in ecological modelling within the context of lake research. The objective was to furnish valuable references in support of the widespread application of ecological models in aquatic environments. Using the 4688 articles collected in the Web of Science (WoS) core database as the sample data source, conducting corresponding data mining and quantitative analysis through visualisation analysis software such as CiteSpace and VOSviewer. From the perspectives of literature output patterns, keyword co‐occurrence networks and future research directions, in‐depth quantitative and visual analysis is carried out on the current status of research on lake ecological models, research institutions, journal publication situations, prolific authors and research hot topics. Through meticulous examination of literature and organisational categorisation techniques, we systematically scrutinised and synthesised the present state, limitations and noteworthy considerations associated with models such as EFDC, CE‐QUAL‐W2, DYRESM‐CAEDYM, AQUATOX, Vollenweider, PCLake, MIKE, WASP and Deflt3D in the context of lake research. Our findings reveal that research focal points from 2002 to 2022 encompass climate change, the ramifications of eutrophication on aquatic ecosystems and the effects of phytoplankton and resuspended sediments on lake management.
