Suspended load and bed-load transport of particle-laden gravity currents : the role of particle – bed interaction

  title={Suspended load and bed-load transport of particle-laden gravity currents : the role of particle – bed interaction},
  author={George W. Bergantz},
The development of particle-enriched regions (bed-load) at the base of particle-laden gravity currents has been widely observed, yet the controls and relative partitioning of material into the bed-load is poorly understood. We examine particle-laden gravity currents whose initial mixture (particle and fluid) density is greater than the ambient fluid, but whose interstitial fluid density is less than the ambient fluid (such as occurs in pyroclastic flows produced during volcanic eruptions or… CONTINUE READING
