| Abstract: | Because of human impacts, lowland rivers are among the most degraded running water ecosystems, with their floodplains being
the center of human activity. Recently, many programs to restore running water ecosystems have been undertaken using various
methods in streams and rivers of North America, Europe, and Far East Asia. However, research and knowledge on the effects
of river restoration in lowland rivers are limited around the world. The restoration project involving the first reconstruction
of a meandering channel in Asia has been conducted in a lowland river section of the Shibetsu River, northern Japan. We review
the geomorphologic and hydraulic characteristics of lowland rivers and their environments for macroinvertebrates and discuss
approaches to restoring macroinvertebrate communities in lowland rivers, using insights from the restoration project in the
Shibetsu River. It is concluded that the recovery of macroinvertebrate assemblages in channelized lowland rivers requires
the implementation of restoration methods to create stable substrates. |
