“…Consider point IV -the intersection of two linear dependences at which "pure dilution" corresponds to the processes in a real water object. If one compares the overall form of equations (6) and (8), they practically coincide. Then the results of calculations based on these equations for the considered case, for the mean annual data, should also be equal to:…”

“…To study the spread of a conservative additive along a river current, the transfer equations are additionally solved [6,7]. It should be noted that when solving a mass transfer equation, in addition to taking into consideration the temperature and dynamic characteristics of receiving watercourses, one must take into consideration the interaction of components with each other [8]. The most common models include GLEN (USA), DRM (USA), QUAL (USA), FINNECOC, ERAUSO (Sweden, Finland), FINEST (Estonia).…”

At present, even for a fairly large surface water object, the effectiveness of the forecasting models of water qualitative composition is largely determined by the completeness and adequacy of the source information. A review of approaches to using such models is given in scientific papers [1, 2]. Traditional forecasting methods, developed for using mod-16. Smirnyagina, N. N., Khaltanova, V. M., Kim, T.

“…Reservoirs play an important role for water resources management by helping store rainwater received from their drainage areas and regulate downstream streamflow. Reservoir operation can alter downstream flow regimes and ecosystems [1][2][3]. Sustainable water resources management requires reservoirs to support both anthropogenic activities and the environment; however, the hydrological and social complexity involved in reservoir decision-making processes makes it challenging to optimize the trade-off between multiple water use objectives [1,4,5].…”

“…Sustainable water resources management requires reservoirs to support both anthropogenic activities and the environment; however, the hydrological and social complexity involved in reservoir decision-making processes makes it challenging to optimize the trade-off between multiple water use objectives [1,4,5]. Various reservoir operation models and strategies have been developed to guide reservoir-river management, but there is still substantial room for improvement in balancing between reservoirs' roles as the sources of water for agricultural water use and the environmental flow (EF) [1][2][3]6,7].…”

Excessive nutrient loadings from drainage areas and resulting water quality degradation in rivers are the major environmental issues around the world. The water quality further deteriorates for the large seasonal variation of precipitation and water flow. Environmental decision makers have been exploring affordable and effective ways of securing environmental flow (EF) to improve the water quality, especially in dry seasons, and agricultural reservoirs have attracted the attention of policymakers as an alternative source of EF. This study proposed an analysis framework for assessing the EF supply potential of agricultural reservoirs as alternative sources of EF. A reservoir water balance model was prepared to mathematically represent the reservoir water balance and quantify temporal variations of the amount of water available for the EF supply. The simulation model was designed to explicitly consider inflow from the upstream drainage areas, irrigation water requirement, and hydrological processes happening in the reservoirs. The proposed framework was applied to four agricultural reservoirs located in South Korea to evaluate its efficiency. Results showed that the additional storage capacity added by the dam reinforcement enabled the study reservoirs to satisfy both needs, EF and irrigation water supply. The surplus capacity turned out to be enough to satisfy various EF supply scenarios at the annual time scale. However, the current operation plans do not consider the seasonal variations of reservoir hydrology and thus cannot supply EF without violating the original operational goal, irrigation water, especially in dry months. The results demonstrate that it is necessary to consider the temporal variations of EF when developing reservoir operation rules and plans to secure EF. This study also highlights the unconventional roles of agricultural reservoirs as resources for improved environmental quality. The methods presented in this study are expected to be a useful tool for the assessment of agricultural reservoirs’ EF supply potential.
