Comportamento Hidrossedimentológico De Bacia Hidrográfica Com Reservatório

Abstract: O represamento hídrico altera a hidrodinâmica do escoamento fluvial e dos processos de transporte e deposição de sedimentos. O presente trabalho tem por objetivo amostrar e analisar o comportamento de sedimentos suspensos em uma bacia hidrográfica de 5ª ordem fluvial, que possui um reservatório d'água em seu exutório. Foram realizadas 20 campanhas de amostragem de sedimentos em suspensão, de 2 a 3 metros a montante da barragem, em quatro profundidades da coluna d´água. Para amostrar a mistura água-sedimentos d… Show more

“…On the other hand, the limitation of the solid discharges that carry in themselves the limitation of the hydrological simulation can be explained by two reasons. The first may be due to the evaluation data observed, since the data used to construct the flow-solid discharge rating curve were sampled by Zanin, Bonuma and Franco (2017) during the wet year of 2014, without taking into account the levels of the aforementioned reservoir during dry periods. The second Hydrosedimentological modeling with SWAT using multi-site calibration in nested basins with reservoirs 20/26 reason may be the structural limitation of the model, since the reservoir module parameters of SWAT are spatially concentrated, while the sediment balance in large reservoirs is not homogeneous throughout their length;…”

“…The RPW has 2 representative reservoirs located in one of its 3 fifth order river sub-basins, called Salto Grande Dam, which belongs to a small hydropower plant and the Caunal Dam which is used to regulate the volume of the Salto Grande Dam (Figure 1). Further details on the contributing basin of the Caunal Dam (199.32 km 2 ), that will be analyzed in this study can be obtained in Zanin, Bonuma and Franco (2017).…”
