Particle aggregates can be regarded as a fourth state of matter which with differing energy levels can display behaviour associated with the other three. This provides the basis for a unified theory of particulate flow in the land scape, ranging from the solid-like soil creep, through plastic flows like solifluction to fluidized phenomena exemplified by fluvial sediment flows wherein bed and suspended loads relate to dense and dilute phases of fluidized beds and therefore to liquids and gases respectively.
The theory of the liquid state is central to any unified theory and this is presented with the aid of Eyring's rate process theory and Frenkel's theory of holes. Applications to geomorphology are noted, to be given detailed treatment on a subsequent occasion.

A critical analysis is made of the assumptions underlying IZ e y n o 1 d s' equations for turbulent flow. It is shown that there are regions in a flow field where these assumptions break down, and it is therefore necessary to separate the flow into a turbulent core and a laminar sublayer. The import
