Abstract
Integrating hydrogeomorphological principles into the restoration of
degraded rivers can achieve sustainable results for a variety of
objectives and human benefits that are consistent with the potential
functioning of rivers as well as their uses. Despite recent management
approaches inspired by these principles, several restoration projects
largely involve controlling river processes and target specific
one-dimensional objectives often associated with the habitat of a few
high-valued fish species or with rivers steadiness and aesthetics.
Although there is overall a lack of post-project monitoring, several
projects appear to have failed or had mixed success. This research aims
to answer the question: What are the real drivers behind river
restoration projects? Four restoration projects in Quebec (Canada) were
characterized through a qualitative research process of support and
interviews with the organizations running them as well as with two
representatives of ministries involved in river restoration and
management. The results identify two major drivers for the formulation
of restoration objectives: project funding and stakeholder expertise. We
propose a new analytical framework including these drivers, which appear
to act as both conditions and motivations guiding the objectives of the
projects and their diversity. Following diverse sociocultural and
legislative contexts shaping these drivers, they may facilitate or
restrict the integration of hydrogeomorphological principles towards
diversified objectives and benefits. This supports regulation that is
better informed by scientific knowledge about hydrogeomorphological and
sociocultural river dynamics, knowledge sharing between academic
researchers and environmental organizations, and collaboration between
stakeholders and communities living around rivers.
