  abstract = {{T}his paper proposes a systematic procedure to identify river reaches from a geomorphic point of view. {T}heir identification traditionally relies on a subjective synthesis of multi-dimensional information (e.g., changes of slope, changes of width of valley bottom). {W}e point out that some of the attributes adopted to describe geomorphic characters of a river (in particular sinuosity and confinement) depend on the length of reaches, while these latter are not yet identified; this is a source of ambiguity and introduces, at least conceptually, an unpleasant, implicit, iterative procedure. {W}e introduce a new method which avoids this difficulty. {F}urthermore, it is simple, objective, and explicitly defined, and as such, it is automatable. {T}he method requires to define and determine a set of intensive attributes, i.e., attributes that are independent of the segment length. {T}he reaches are then identified by the intersection of the segmentations induced by such attributes. {W}e applied the proposed procedure in two case studies, the {M}agdalena {R}iver ({C}olombia) and the {B}aker {R}iver ({C}hile), and investigated whether the adoption of the traditional approach for the definition of reaches would lead to a different result. {W}e conclude that there would be no detectable differences. {A}s such, the method can be considered an improvement in geomorphic river characterization.},
