Description :
Analytical hydraulic geometry equations are combined with a watershed model to quantify downstream trends in equilibrium fluvial morphology in gravel streams. The hydraulic geometry equations relate fluvial morphology to discharge, bedload transport rate and grain size; these independent variables are in turn determined by routing gravel supplied at zero-order basins through a channel network. The resulting model specifies the discharge, bedload transport rate, grain size, width, depth, slope and river bed elevation at every point in the drainage basin.
