I& Abstract (Limit: 200 words)
A study was conducted for the resolution of sediment source areas in the Big
Sandy River basin, southwestern Wyoming. Suspended-sediment and bedload data were
collected in order to determine total sediment transport at several locations within
the basin.
The bedload data were compared to the Einstein bedload function and total load data
were compared to the Colby method. The bedload comparison showed a higher estimation of
transport rates with Helley-Smith sampler measurements than with the Einstein bedload
function. The Colby method yielded higher transport rates at high flows and lower
transport rates at low flows than the measured total transport rate.
The Big Sandy Reservoir acts as a control in the basin. The area upstream of
the reservoir was interpreted separately from the area downstream for source-area
determination. In the arid plains upstream of the reservoir, the amount of
sediment transported increased 98 percent with an increase in runoff of only
1 percent.
