Description: Abstract - Sediment transport capacity mediates the transfer and storage of bed material between alluvial reservoirs in a drainage system. At intermediate time scales corresponding to the evolution of sediment pulses, conditions governing bed-material transport capacity under the hydrologic regime respond to variations in storage and sediment flux as pulses extend, overlap, and attenuate through the network. Relations between transport and storage in degrading gravel-bed channels and general relations between bed-load transport rate and tractive force have similar inflection points marking the inception of armoring.
