Title

Hydraulic geometry in river channel networks as a method for the assessment of river condition

Author(s)

Abstract

Aspects of channel morphology were examined across the stream network in the Kangaroo River catchment, NSW. Downstream hydraulic geometry relationships were analysed as appropriate methods of predicting alterations in channel morphology with increasing scale within a network context. Examining river network behaviour in this way enhances understanding of the way in which geomorphic processes behave across networks. This in turn provides scientific grounding for stream management on a network scale. A similarity between downstream and network hydraulic geometry relations was found, suggesting the potential for modelling adjustment in channel form to discharge regimes across the network. The potential for the use of network hydraulic geometry relationships in assessments of river channel condition is discussed.
