Understanding the patterning of near bed flow around an obstacle is the first step towards understanding the processes that control the depth and extent of any resulting scour. Both newly collected and previously published data are used to describe flow patterning around a wide variety of 3D obstacles in unidirectional flow. The extent, location and asymmetry of wake features are shown to vary considerably with obstacle size, shape and orientation. The along flow extent of affected flow regions is also shown to scale with the Reynolds number, up to a critical value (Re?10^4), with implications when modelling flow interaction and hence scour at small scales in the laboratory.
