This work presents various simulations of flow and transport processes for the Itaparica Reservoir in northeast of Brazil. Flow conditions and spreading of tracer were simulated for mean flow conditions as well as for a drought and a flood case using the TELEMAC-2D model. The simulations indicate that the stream in the main river dominates the flow field for mean flow as well as for the drought, while in the bays the water is almost stagnant and a tracer injected at the inflow boundary is mainly transported downstream without entering the bays. For the flood case, the flow velocities considerably increased in the whole reservoir. Therefore, a tracer injected at the inflow boundary enters parts of bays. It was found out that in the flood case the friction coefficient is very sensitive.

Abstract
This work presents various simulations of flow and transport processes for the Itaparica Reservoir in northeast of Brazil. Flow conditions and spreading of tracer were simulated for mean flow conditions as well as for a drought and a flood case using the TELEMAC-2D model. The simulations indicate that the stream in the main river dominates the flow field for mean flow as well as for the drought, while in the bays the water is almost stagnant and a tracer injected at the inflow boundary is mainly transported downstream without entering the bays. For the flood case, the flow velocities considerably increased in the whole reservoir. Therefore, a tracer injected at the inflow boundary enters parts of bays. It was found out that in the flood case the friction coefficient is very sensitive.| File | Dimensione | Formato | |
