Early work by Leopold and Wolman (1957) differentiated alluvial channel types based on the controlling variables of discharge and gradient (Figure 2.2). Three classic channel types were recognised: meandering, wandering, and braided. The thresholds defining shifts between these channel types were observed to be mainly dependent on the calibre of the bed material present in the channel with braiding occurring at lower gradient/discharge values than gravel systems.
