Quantification approach
Data source
Water Audit Monitoring Report 2009–10 (22 February 2011).
Water audit monitoring (WAM) report data are stored in the Murray–Darling Basin Authority (MDBA) HYDRO database.
Data provider
MDBA.
Method
South Australian data are based on the assumption that all stock and domestic entitlements diverted the full value of their entitlement.
Uncertainty
40% for South Australian MDB region.
Approximations, assumptions, caveats/limitations
- Uncertainty reported for diversion at the abstraction point account for possible errors in the data collection process.
- Uncertainty of diversion at the diversion point: a single metered abstraction point may provide water to a range of users, under various types of entitlements (e.g. stock and domestic class). When this happens, the jurisdiction may split the metered abstraction into several classes of entitlements or types of users, according to priority rules governing the entitlements. This split has an inherent uncertainty that is not considered here.
