Description :
A method for analysing longitudinal variations in cross-sectional shape and channel slope is developed and demonstrated with an application to the Wimmera River, Australia. The method involves characterising the geometry and spatial location of individual cross-sections using 4 parameters and then conducting statistical analyses of the parameters from a set of cross-sections. The application to the Wimmera River identifies longitudinal trends and variability in cross-section characteristics, including quantification of differences in channel characteristics associated with a quasi-periodic switching between 2 different channel plan forms (single-thread and anastomosing).
