geomorphological unit hydrograph schemes based on the width function:
- 1F1U1P: 1 velocity applied to entire flow path length
- 1F2U2P: 2 velocities (respectively on hillslope and channelized length) -
- 2F2U3P: 1 velocity for surface flow, 1 velocity for subsurface flow
- 2F3U4P: 2 velocities for surface flow, 1 velocity for subsurface flow
In any case, the poster you can retrieve below the figure (click on the figure) tells it all.
