Abstract

Variation in river hydraulic geometry throughout stream networks is central to the problems of catchment management because of its influence on flow and sediment routing, physical habitats and channel-floodplain interactions. In its simplest form, at-a-station hydraulic geometry is described by power functions relating the surface width, water depth and mean velocity at a channel cross-section to discharge. This paper extends hydraulic geometry analysis to represent the mean and variation of hydraulic characteristics along a river reach as power functions of discharge. Using 54 surveys of 17 river reaches, mostly in south east Australia, it is shown that five reach hydraulic variables are su..
