| description | The study estimates the bed load sediment in the middle
Araguaia River, through the height and dunes daily displacement.
The studied region is located between the mouth of the Crixás-Açú
River and the Bananal Island, Goiás. The dunes migrated at the
rate of 7 m/day, the average water velocity was 1.25 m/sec, corresponding to a total transport of 2195.60 ton of bed load/day.
Two methods were compared in order to verify possible sources of
error, the Van Rijn one showed a difference of 1414 tons less then
the Struckrath method, difference of 0,06% in the estimated bed
load between both methods. Results were compared with the bed
load of the Araguaia River in the region of Aruanã. |
