DESCRIPTION:Suspension and transport of particulate material is critical t
 o a wide variety of environmental and industrial processes. In this talk\,
  the fundamental mechanics of particulate transport in open channel flow a
 re reviewed as an introduction to predicting and understanding the dynamic
 s of buoyancy-driven sediment-laden flow\, turbidity current. Turbidity cu
 rrents represent some of the largest movements of material on the planet's
  surface\, yet how they traverse vast distances on the seafloor remain eni
 gmatic. Here experiments\, and field work\, are used to highlight the pote
 ntial importance of coherent flow structures and non-local mixing. Lessons
  learnt from turbidity current hydrodynamics are then applied to revise pa
 rticulate transport in classical shear flow\, providing an insight as to w
 hy classical models are poor at predicting sediment transport in real-worl
 d environments.\n
