Stratigraphic sequences formed of coarse clastic sediments represent the consequences of bedload transport and deposition. Interpretation of stratigraphic sequences is based on both an understanding of the physical processes of sediment transport and deposition and on the opportunities for stratigraphic preservation. Research on coarse gravel transport indicates that bedload does not move at a constant rate, even when flow conditions are nearly constant (Gomez, 1991; Prestegaard and Plotnick, in press). Interpretation of variations in bed thickness or sediment size distributions in the stratigraphic record require realistic models of bedload transport and deposition that can predict not only average conditions, but expected variations in these processes.
