DRIFT is a holistic environmental flow methodology that provides detailed, transparent predictions of how ecosystems will change under a range of selected water development and management scenarios, and how users of those ecosystems may be affected by these changes.
DRIFT provides a basis for assessing the environmental impacts of a given project at basin or site specific level on the river ecosystem and its dependent biota and stakeholders, and for identifying and evaluating appropriate mitigation strategies.
The findings and outputs of DRIFT are often used as the basis for discussion and negotiation between regulatory authorities and other stakeholders to determine the agreed development strategy for a basin, sub-catchment or a specific project (e.g. hydropower).
Increasingly DRIFT is being applied in a whole basin setting where the opportunities of offsets and avoidance through careful and intelligent planning are far greater than at a project scale.
