Hydrodynamics And Transportation In The Rio Verde Reservoir

The characteristics of hydrodynamic circulation and the transport of contaminants is discussed in this work in order to add to our understanding of the phenomenon of eutrophication in the Rio Verde Reservoir. Models used in the analysis are part of SisBaHiA (R) (in Portuguese, Sistema Base de Hidrodinamica Ambiental). SisBaHiA (R) is a set of models that is able simulate coastal and inland water bodies. In this study, we used the horizontal two-dimensional hydrodynamic circulation model (2DH) and the vertically integrated model of water quality and eutrophication for non-conservative and passive scalars. Results from environmental modeling show that the chosen models are suitable and can be used quantitatively in characterizing the excessive algae growth in reservoirs, thus providing the foundation for new applications and developments. Despite the errors associated with boundary conditions and the simplifications considered herein, the model has demonstrated its potential to adequately simulate the data set collected from the reservoir. Based on the results of the hydrodynamic model, we noted the significant influence of wind in determining hydrodynamic circulation in the Rio Verde Reservoir. Inflows/outflows only generate impacts in circulation in their immediate surrounding regions and do not contribute to the circulation of the reservoir as a whole.
