Advances in topographic survey and terrain modelling have enabled a revolution in the
study in the fluvial morphodynamics in the last decade. Prior to the advent of electronic
tacheometry in the 1990s, the analysis of channel dynamics was typically inferred from a
combination of cross-section surveys and planform mapping. Distributed surveys acquired
with GPS or EDMs enabled this analysis to be dimensionally extended and the pattern and
magnitude morphodynamics elucidated in 3D; in particular through DTM differencing …
