“…Raei et al [108] applied NSGA II on a hypothetical area to design an optimal in situ groundwater bioremediation system. NSGA was also used by Zmijewski and Wörman [55] to optimize the tradeoff between hydropower production and reduction of the transport of phosphorus in the reservoir network of the Dalälven River, Sweden. Another form of heuristic algorithm method called Multi-Objective Artificial Bee Colony-based optimization approach (MOABC) was applied to allocate water quality monitoring stations in the Great Fish River, South Africa [109].…”

“…In Europe, over the past few decades, nutrient runoff from agricultural areas becomes a problem to coastal sea environments and estuaries which creates eutrophication. Laamanen et al [53], Rabalais et al [54], and Zmijewski and Wörman [55] used multi-criteria decision in the Dalälven River (Sweden) to reduce the phosphorous load supplied to downstream aquatic environments. According to a report by the European Environment Agency: State of the Environment Report 2015, around half of the European rivers and lakes have been polluted.…”

The water allocation problem is complex and requires a combination of regulations, policies, and mechanisms to support water management to minimize the risk of shortage among competing users. This paper compiles the application of multi-criteria decision-making (MCDM) related to water allocation. In this regard, this paper aims to identify and to discern the pattern, distribution of study regions, water problem classifications, and decision techniques application for a specific water allocation problem. We applied a systematic literature review study from 2000 to 2019 by using four literature databases (Web of Science, Scopus, Science Direct, and Google Scholar). From 109 papers, 49 publications have been identified and information extracted. This study reveals that in the past two decades the application of MCDM in the area of water allocation has increased particularly after 2014. Around 65% and 12% of study papers were conducted in Asia and Europe, respectively. Water shortage, water use management, and water quality were consecutively the most top-ranked discussed water problems. NSGA II (non-dominated sorting genetic algorithm), GA (genetic algorithm), and LP (linear programming) are the more often applied decision methods to solve water allocation problems. The key findings of this study provide guidelines for future research studies.

“…Various models for the simulation of ecological processes in lakes have been developed during the last decades, from mechanistic (or process-based) models to empirical models (Vinçon-Leite and Casenave, 2019), and from static models to dynamic models, to agentbased models (Jørgensen and Bendoricchio, 2011). Although the static models are based on simplifying assumptions, their low computational demand is an advantage in the large-scale assessments of eutrophication and P retention (Maavara et al, 2015;Radomski and Carlson, 2018;Wu et al, 2021;Xu et al, 2020), optimization of reservoir operation rules (Chen et al, 2019;Deng et al, 2020;Xu et al, 2021;Zmijewski and Wörman, 2017), the evaluation of manipulative plans for lakes with the risk of eutrophication (Estalaki et al, 2016;Kasprzak et al, 2018), and paleolimnological studies (Moyle and Boyle, 2021). Though N and P are both vital for algae growth in the aquatic environment (Lewis and Wurtsbaugh, 2008;Liang et al, 2021), it is widely believed that the control of P seems the most promising approach for reduction of algal blooms in freshwater systems (Kazmierczak et al, 2021;Le Moal et al, 2019;Schindler, 2012;Smith and Schindler, 2009;Tong et al, 2017).…”

“…Wang et al (2020) used the Indicators of Hydrological Alteration to estimate the ecological flow demand in the optimization of a multireservoir system in northern China, and the results showed that water use provided ecological benefits. Zmijewski and Wörman (2017) evaluated phosphorus migration in a river basin and used genetic algorithms to determine the trade-off between power generation by the reservoirs and phosphorus loss in the Dalälven River, Sweden. However, assigning weights to different objectives is highly subjective.…”

Reservoirs store and regulate natural water resources, playing a vital role in water supply, power generation, flood control, and shipping (Biemans et al., 2011;Chen et al., 2019;Kibler & Tullos, 2013). Consequently, the construction and operation of reservoirs affect the ecosystem, mainly manifesting as changes in hydrological conditions downstream. In most cases, the human-controlled discharge process is more stable, altering the flow regime formed by long-term natural evolution that is required by downstream aquatic ecosystems, thus endangering them (Jiang et al., 2019).Fish have a high trophic level in aquatic ecosystems, and their population size and species richness reflect the changes in the aquatic ecosystems (Mišetić et al., 2003;Wu et al., 2014;Zhao et al., 2015). In some systems, fish spawning coincides with the onset of flooding, and they gather at the spawning grounds to lay eggs when the flood increases and leave after it finishes (Tao et al., 2017). The key ecological requirements for the hydro-environment in the upper reach of the Yellow River in China during the spawning season include the flow regime, as the development of the fish gonads requires stimulation of the flow rising process; the water depth, as the hatching of benthic eggs requires a gentle water flow with little amplitude variation; and water temperature, with the appropriate temperature for fish spawning and egg incubation being approximately 14°C-15°C (Li et al., 2020). Table 2 in Bejarano et al. ( 2017) describes the changes in the environmental and biological responses caused by short-term flow regime changes, including the destruction of the habitats of fish and other species, impact of migration activities, and reduction of species diversity. With increased attention paid to the ecological environment, improving the current reservoir operation schemes and restoring the river's ecological flow processes, especially during critical physiological processes, such as fish spawning and migration, have become key objectives in reservoir operations.The objectives of reservoir operation are often incommensurable or even conflicting. Multiobjective optimization models, which simultaneously consider different objectives of reservoirs, such as power generation and ecological protection, are required to address these problems (Bai et al., 2019;W. He et al., 2020). Multiobjective optimization models are solved to determine the quantitative relationship among objectives and formulate a scheme balancing them (Tang et al., 2019).The existing multiobjective optimization models of reservoir operations, which consider resource exploitation and ecology, mostly use the weighting of each objective to reduce dimensionality or obtain a set of Pareto optimal
