Hydraulically Driven Jamming of Rods

Hydraulically driven flow of filament-like objects has a broad range of natural and industrial applications such as log jams in rivers, or the clogging of an open channel irrigation ditch in agriculture. To investigate the phase space of the jamming of rods in a fluid driven flow, we have performed experiments on buoyant particles over a range of aspect ratios in an open channel flume with a gated restriction, and quantify the results as a function of channel geometry, Froude number and density of logs in the channel.
