Abstract
This research aims to formulate an approach that will allow for the opportunity
mapping for stage zero river restoration in the Tweed catchment, in Scotland. The
methodology developed first assesses the suitability of valley bottoms by taking into
account their geomorphological features and anthropogenic constraints. The
methodology then works on identifying relic stage zero river surfaces to be re established using the Geomorphic Grade Line (GGL) method and GIS tool developed
by Powers et al, (2018). Results found 22 and 16 potential sites for stage zero river
restoration in the Teviot and Till sub-catchments, respectively. A scoring system was
developed to rank these identified potential sites in terms of restoration suitability.
Site surveys and engagement with a local river restoration practitioner concluded that
the developed methodology has successfully allowed for the opportunity mapping
for stage zero river restoration. However, the methodology does not consider the
restoration's feasibility. Hence, the results of this approach need to be combined with
knowledge from local river restoration practitioners and stakeholders to conclusively
identify sites for stage zero river restoration.
