This paper introduces this special issue of Aquatic Sciences. It outlines a multi-scale,
hierarchical framework for develo** process-based understanding of catchment to reach …

Geomorphic units are the elementary spatial physical features of the river mosaic at the
reach scale that are nested within the overall hydromorphological structure of a river and its …

As part of an hierarchical, multi-scale, hydromorphological framework for European rivers
that has been developed within the REFORM project, a procedure for classifying rivers has …

Hydromorphological stream assessment has significantly expanded over the last years, but
a need has emerged from recent reviews for more comprehensive, process-based methods …

Natural processes and human activities both cause morphological changes in channels.
Remote sensing products are often used to assess planform changes, but they tend to …

This paper relates life cycle characteristics of fishes, their environmental tolerances, habitat
requirements, and resilience against hydromorphological disturbances to a recently …

Rivers and their floodplains are among the most important natural environments in the UK
and Republic of Ireland. Compared with other ecosystems, rivers support a …

The effects of river restoration on hydromorphological conditions and variability are often
documented immediately following the restoration, but rarely properly monitored in the long …

The EU Water Framework Directive (WFD) introduced the term 'hydromorphology', which
requires the consideration of any modifications to flow regime, sediment transport, river …

The hyporheic zone (HZ) is an area of interaction between surface and ground waters
present in and around river beds. Bidirectional mixing within the HZ, termed hyporheic …
