Site ID: 30 Lat. 22.0102 Burma Sagaing
River: Chindwin Long. 95.1426
Site name: Monywa Contributing area: 112080 km2 Ratio to Comparison Station: 7.72
Latest measurement: 19-Jul-10 Mean annual runoff: 494 mm (2003-2009)
Hydrologic status: 2 Normal flow Total runoff this year (2010): 259.4 mm
Latest M/C ratio: 1.19 Seven day total: 11.9 mm
Estimated current discharge: 1679 m3/sec Percent of mean 7-day total: 79.8 % (today's value compared to mean for same period, 2003-2009)
Ice-cover determination: 5 yr recurrence flood: 7642 m3/sec (from Log Pearson III analysis)
Status Codes:  1 = Low flow or ice, 2 = Normal flow, 3 = Flood, 4 = Major Flood 7297 m3/sec (from Gumbel Extreme Value analysis)
Comparison Station Information:  Toungoo (2261500)           Contributing Area:   sq mi 14520 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. Accuracy Estimate: Poor. Comparison basin is much smaller.
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.
