Abstract

The Pitt River is a meandering rier channel linking the Fraser River estuary and Pitt Lake. Calculations indicate that during the flood, basal shear stress peaks earlier in the cycle and reaches higher values than during the ebb. Thus, sediment moves further forward on a flood flow than it moves back on the succeeding ebb. An upstream movement of sediment in Pitt River from the Fraser River is indicated by: 1) the identical mineralogy of the two rivers; 2) a decrease in median grain size from the Fraser to Pitt Lake; and 3) a predominance of flood-oriented bedforms in the river channel.- from Author
