identified, to model relationships between these types and
the driving-processes. A range of strategies can be applied
to extract information. As shown by Piegay and Schumm
(2003), geographic patterns of hydrographic networks
can be used to both highlight similarities between fea-
tures at different scales (inter-object comparisons within
a catchment or between catchments) and, by considering
longitudinal trends, to provide information on sources
and on local controls on sediment transfer (Table 11.1).

In the first case, it is possible to sample features and
work on inter-object comparisons, sampling being driven
by the working hypothesis. The comparison of geographic
objects is not a new perspective, getting its roots in the
hydraulic geometry approach and allogenic modelling
(Church and Mark, 1980). In this area, research has mainly
focused on channel planforms and notably on meandering
geometry and cut-offs in a synchronic approach or in a
diachronic way looking at channel shifting.
