Dynamics of channel incision in a granular bed driven by subsurface water flow
A. E. Lobkovsky, B. Smith, A. Kudrolli +1
We propose a dynamical model for the erosive growth of a channel in a granular medium driven by subsurface water flow. The model is inferred from experimental data acquired with a…
Failure of a granular step
Saloome Siavoshi, Arshad Kudrolli
We investigate the gravity driven rapid failure of a granular step composed of non-cohesive steel beads. The step is initially held together with electromagnets, and released when…
Threshold phenomena in erosion driven by subsurface flow
Alexander E. Lobkovsky, Bill Jensen, Arshad Kudrolli +1
We study channelization and slope destabilization driven by subsurface (groundwater) flow in a laboratory experiment. The pressure of the water entering the sandpile from below as…
Velocity profile of granular flows inside silos and hoppers
Jaehyuk Choi, Arshad Kudrolli, Martin Z. Bazant
We measure the flow of granular materials inside a quasi-two dimensional silo as it drains and compare the data with some existing models. The particles inside the silo are imaged…
