“…The module can work directly on standard templates (Figure 4), covering different combinations of water quality processes (eutrophication, heavy metals, sediments and vegetation, biochemical oxygen demand or dissolved oxygen) or can be adjusted according to the specific needs of each aquatic environment [34; 11] and can be applied to simple cases, where the major problem is oxygen depletion, as well as to more complex cases, where the effects of biochemical oxygen consumption must be considered [20; 6] or that can describe nutrient cycling through quantitative scenario assessments [17]. Level 1 of the model was used in this study and includes for dissolved oxygen reaeration processes and for biochemical oxygen consumption it includes processes of oxidation or decomposition of organic matter [25].…”

For the simulation of hydrodynamic changes and pollutant dispersion in the study area, an appropriate model was applied using the DHI series software. Flows were modelled using the hydrodynamic model and the hydrological model, and water quality was modelled using MIKE 11 ECO LAB. The paper presents a simulation for the water quality of the Bahlui River. Mike 11 contains a GIS map and simulation editors. Water quality parameters such as temperature, dissolved oxygen and biochemical oxygen demand were simulated. Modelling results can be used as a planning tool to help decision makers during different phases.

“…Another feature of the water system is its dynamism, i.e., any process in the environment should be considered in time. Research papers [8]- [10] show that mathematical models used to study the water environment are complex and diverse in their structure. To build models of this type, it is very important to correctly formulate the problem statement and generalize the available initial data, then choose the optimal solution method.…”

<span>The task of the research was to build and analyze a model of the dynamics of pollution of a flowing reservoir and systems of communicating reservoirs with and without taking into account water filtration in the soil as a result of external sources (effluents from industrial enterprises). This work was aimed at studying the change in temporal dynamics, taking into account the concentration of impurities in the volumes of three reservoirs during the periods of discharge and completion, lasting 30 days. Numerical experiments were carried out for various flow rates and compositions of filtration coefficients to study the relaxation times of pollution in the system of reservoirs. Also, software was developed that analyzes the change in the concentration of impurities in the system of reservoirs. As a result, it was found that the pollution pattern is more dependent on the topology of the watercourse network.</span>
