Description: Abstract - Dynamic equilibrium in stream channels has traditionally been applied on the reach scale, where fluxes of water and sediment into a reach result in rapid but minor adjustments of channel dimensions, hydraulics or roughness (equilibrium), or aggradation and degradation (disequilibrium). Such an essentially one-dimensional spatial approach to sediment-channel interactions implicitly avoids a long standing and difficult problem: how do large inputs of sediment travel through channel systems and thereby distribute the fluxes to which channels respond at any time scale?
