Groundwater resource allocation, East Gnangara

The scope and objectives of the East Gnangara Environmental Water Provisions Plan encompassed a number of factors, including:

• identification of ecosystem components with high environmental and social values,
• determination of environmental water requirements (EWRs) and EWPs for each ecosystem component,
• determination of quantity of water available for public and private groundwater abstraction,
• computer modelling of differing abstraction scenarios to model likely impact of groundwater abstraction,
• prediction of the changes in water levels induced by groundwater abstraction, to determine if conflicts are likely,
• proposed long-term management and monitoring of groundwater in the study area.
