Abstract:

The results of numerical models of supercritical flows on alluvial fans demonstrate the strong effect fan topography has on flow velocity and depth. Particularly important are transverse gradients, which can produce high-velocity and high-discharge jets on high-slope areas defined by the fan topography.
