Theme 3: River and coastal settings - Classifying tropical rivers

Theme Leader: 
Peter Davies

Peter DaviesThe rivers and estuaries across northern Australia can differ substantially between catchments. Differences in riverscape setting - primarily their flow patterns and how they form and evolve - are likely to influence ecosystem processes, the potential types of developments and the likely response to development and climate change.  In Theme 3 a physical classification system is being developed so we can determine the degree to which information is transferable from one catchment to another.

We are also seeking to understand the demographic and economic character of local communities in nominated catchments, and how this relates to the physical classification.

Projects

An understanding of the socio-economic systems and their relationships with the environment is a key component in assessing the implications of future developments in northern Australia.  This project will study a range of economic, cultural, institutional and human-capital aspects of northern populations to look for differences and similarities among communities and to describe how the region's socio-economic systems might change under the different future development scenarios.

A universally accepted system of classifying riverscapes (i.e. a geomorphic river classification scheme) does not exist for the tropical north of Australia.  This project will develop such a classification and so provide an understanding of the diversity of riverscapes in northern Australia.  It will also provide a rational basis for extrapolating limited, site-specific data collected in the TRaCK program to the rest of the wet-dry tropics.

River classifications identify the key features that make rivers different or similar and so provide a tool by which the insights and knowledge gained in one river or region may be meaningfully applied or transferred to another.  This project proposes to develop a regional classification of Australia’s rivers based on ecologically relevant aspects of their hydrology (i.e. an ecohydrological classification).
