Summary

This chapter provides a framework with which to analyse river diversity in any field situation. It presents a brief discussion of the cross-scalar approach to analysis of rivers. Insights on bed material size, bedforms and channel and floodplain geomorphic units are brought together in a framework that can be used to analyse any given river. The diversity of rivers is framed along a continuum that extends from bedrock-dominated erosional landscapes through to alluvial rivers. The character of bedrock and partly confined rivers is outlined. The range of alluvial rivers is documented in relation to measures of channel planform, followed by an outline of the constructivist approach to river analysis, viewing reaches as assemblages of channel and floodplain geomorphic units. Summarizing the discriminating functions used to differentiate among river types, the chapter finally provides a brief description of a generic approach to analysis of river systems, the River Styles framework.
