Laboratory Debris Flow Experiments: A Study of Erosion
… distribution in experimental debris flows and erodible beds. We systematically and independently varied the composition of each the supply and erodible bed material and the flume inclination angle, ϕ. Then, we demonstrate that there is a unique neutral angle, ϕN (the angle at which erosion is …

Scour in regions of flow separation with free-surface effects
… were delineated for a wide variety of fixed bed structures, based on both new experiments and reanalysis of others' experiments with new dimensionless parameters, in an effort to form a generalized picture of regime phenomena. ^ Scour downstream of what was initially a backward-facing step …

Experimental Investigation of Turbulent Flows at Smooth and Rough Wall-Cylinder Junctions
… this dynamically-rich phenomenon have been described within the body of a rapidly-expanding literature. Nevertheless, important aspects remain inadequately understood and call for further scrutiny. This study emphasized three of them, by investigating the effects of: model scale, wall roughness, …

Avalanching on dunes and its effects: Size statistics, stratification, & seismic surveys
… surveys. Firstly, I describe experiments on erodible, unbounded, grain piles in a channel, slowly supplied with additional grains, and I demonstrate that the behaviour of the consequent, discrete avalanches alternates between two regimes, typified by their size statistics. Reconciling the …
