Abstract / Summary:
Water is becoming an increasingly valuable commodity. In Australia, like elsewhere, the increasing demands for water for both consumptive and environmental uses are resulting in competition for water. All users of water recognise the variability of water availability as a result of climate and man
s intervention in rivers and groundwater systems. Few users recognise the impact of land-use on water availability, so this report is an important step forward in this area. With the tools described in this report, we are able to assess the changes to mean annual streamfl ow as a result of changing vegetation within that catchment. This information is vital in assessing the trade offs between the benefi ts and costs of major land-use change.
This report describes some of the work conducted by the Cooperative Research Centre for Catchment Hydrology
s program concerning land-use impacts on rivers. The program is focused upon the impact of man
s activities upon the land and stream environment upon the physical attributes of rivers. We are concerned about managing impacts for catchments ranging in size from a single hillslope to several thousands of square kilometres. The specific impacts we are considering are changes in streamflow, changes to in-stream habitat by the movement of coarse sediment and changes to water quality (sediment, nutrients and salt). If you wish to find out more about the program
s research we invite you to first visit our website at http://www.catchment.crc.org.au/ landuseimpacts .
