Understanding the relative role of dispersion mechanisms across basin scales

• We analyze dispersive contributions to hydrologic response through scales. • We consider an idealized basin with variable shape, drainage density and scale. • Kinematic dispersion counteracts geomorphological one for medium size basins. • Random variability of hillslope velocity adds positive kine...

• We analyze dispersive contributions to hydrologic response through scales. • We consider an idealized basin with variable shape, drainage density and scale. • Kinematic dispersion counteracts geomorphological one for medium size basins. • Random variability of hillslope velocity adds positive kinematic dispersion. • Non-uniform runoff production yields an additional geomorphic dispersive term.
