1976 bedload measurements, East Fork River, Wyoming.

Quantitative measurements of bedload-transport rate in the East Fork River, Wyoming, show large spatial and temporal variabilities in traction load. The standard deviation for 1-min increments of the mean transport rate is commonly 50-100% of the mean transport rate. The transport rates measured individually over eight equal-length increments of channel width indicate greater than 10-fold variations in transport rates from subwidth sections of minimum transport to subwidth sections of maximum transport.
