Urban riverscape assessments: a framework to assess complex social-ecological systems

Urban riverscapes, comprising the river channel, connected floodplain, and their biotic communities, are complex socioecological and hydrogeomorphic systems, often degraded yet highly valued by communities. The linkages between altered physical, hydrological and ecological conditions and human values and uses are often opaque, making it difficult to develop, justify, and fund appropriate restoration, renovation or protection approaches. To plan for urban riverscapes which support human connections and values, we developed a flexible yet structured framework to assess urban riverscape condition and trajectory. The framework provides a structure to assess multiple riverscape facets (e.g. human connections, hydrology, geomorphology and ecology), and the connections between them, at multiple scales (e.g. watershed, riverscape and reach). In developing the framework, we drew on non-urban analogues from environmental flows and hydrogeomorphic methods, and the development of two recent urban stream assessment methods in the US and Australia. Despite the challenge of integrating social, ecological and hydrogeomorphic science, an integrated process-based stream assessment framework that provides a consistent evaluation approach and incorporates stream values can advance urban stream planning and management, reduce maintenance, and improve stream health as well as the livability of our cities.
