- Abstract
Eutrophication is one of the main problems in water quality, especially in water bodies used as sources for drinking water supply. The main cause of eutrophication lies in the contribution of nutrients that reach the water body from its catchment, increasing its productivity and causing negative effects such as toxic algal blooms. In recent years, the application of numerical water quality models has been a useful tool for evaluating and predicting environmental problems such as eutrophication, consequently a valuable tool for the management of water resources. In general, these models are preceded by hydrodynamic modeling. In this work, the two-dimensional numerical model MIKE 21 is applied to the San Roque reservoir (Córdoba, Argentina). It was used to study and evaluate the dynamics of hydrodynamic and water quality variables associated with eutrophication processes and in response to flood events that occurred in the period January-April 2017. The hydrodynamic variables (speed and water levels), the biological water quality variables (chlorophyll a), and inorganic variables (dissolved oxygen, phosphorus and nitrogen) were modeled evaluated. The results showed the effect that flood events had on the spatial and temporal distribution of these variables. The model presented a good performance with respect to the hydrodynamic and inorganic water quality variables with Absolute Percentage Errors (MAPE) below 10 %. However, a lower adjustment of the biological water quality variables was observed.
