Abstract / Summary:
Predicting the Effects of Large-Scale Afforestation on Annual Flow Regime and Water Allocation: An example for the Goulburn-Broken Catchments
Preface
Trees use more water than grass. This simple statement has important implications for managing dryland salinity and changes in river flows. Until recently the data analysis and predictive tools only permitted confidence in predictions concerning river flows on a mean annual basis. This limited the use of the science in the day-to-day management of water resources and catchment planning.
This report bridges part of the gap between the science of catchment water balances and the management of catchments. The language has moved from "annual average yield" to "water security". Afforestation and water remains a contentious issue. This report sets out an important case study to underpin future decision-making.
This work has been 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 I invite you to first visit our website at http://www.catchment.crc.org.au/programs/projects/index.html.
