Site ID: 24 Lat. -16.8373 Australia Queensland
River: Gilbert Long. 141.3534
Site name: Delta Downs Contributing area: 41905 km2 Ratio to Comparison Station: 3.59
Latest measurement: 14-Jul-10 Mean annual runoff: 325 mm (2003-2009)
Hydrologic status: 2 Normal flow Total runoff this year (2010): 202.7 mm
Latest M/C ratio: 1.08 Seven day total: 3.4 mm
Estimated current discharge: 223 m3/sec Percent of mean 7-day total: 103.5 % (today's value compared to mean for same period, 2003-2009)
Ice-cover determination: 5 yr recurrence flood: 9083 m3/sec (from Log Pearson III analysis)
Status Codes:  1 = Low flow or ice, 2 = Normal flow, 3 = Flood, 4 = Major Flood 8509 m3/sec (from Gumbel Extreme Value analysis)
Comparison Station Information:  Rockfields (5109170)           Contributing Area:   sq mi 11682 sq km
(Data from this gaging station are used for the calibration to discharge, with an adjustment for different contributing areas)
Notes: Calibration to nearby ground station has been accomplished. Estimated accuracy:  Fair. Low flow values (223 m3/sec) may be too high.
Discharge and runoff, based on satellite remote sensing (NASA AMSR-E data)

Discharge is estimated via a rating equation directly from the remote sensing data (M/C ratio) shown below.
Explanation:   Green line records upwelling microwave emission from within 5 km radius of a calbration land target; blue line is emission from within 5 km radious of the measurement target centered over the river.
Brown line is their ratio (M/C; scale on right) and is used to estimate river discharge via a rating equation.
Rating equations are being developed and applied on an individual basis. For calibration status, see "notes" entry, above.
