A New Paradigm for Catchment Management: Detection, Forecasting and Management of Water Catchments With Multiple Steady States

Grant number: LP0991280 | Funding period: 2010 - 2013

Completed

Abstract

Understanding the response and recovery of Australia's water catchments to climatic change and variability is become increasingly urgent. Our catchments are vulnerable because there is a fundamental gap in our understanding of how they recover from high or low rainfall periods. This project will: a) advance water management concepts; b) build tools to understand how and when catchments might switch to new states when hit by a disturbance; and c) identify how best to build the buffering capacity to reduce the chance of a switch occurring. The project will make Australia's groundwater and streamflow resources more secure and make Australian researchers and water resource managers world leaders..
