Site ID: 71 Lat. -17.5362 Zambia Western
River: Zambezi Long. 24.6114
Site name: Sesheke Contributing area: 338827 km2 Ratio to Comparison Station: 8.92
Latest measurement: 31-Aug-11 Mean annual runoff: 41 mm (2003-2009)
Hydrologic status: 2 Normal flow Total runoff this year (2010): 59.6 mm
Latest M/C ratio: 1.17 Seven day total: 0.5 mm
Estimated current discharge: 257 m3/sec Percent of mean 7-day total: 111.5 % (today's value compared to mean for same period, 2003-2009)
Ice-cover determination: 5 yr recurrence flood: 1990 m3/sec (from Log Pearson III analysis)
Status Codes:  1 = Low flow or ice, 2 = Normal flow, 3 = Flood, 4 = Major Flood 1829 m3/sec (from Gumbel Extreme Value analysis)
Comparison Station Information:  Kamativi G/w (1491200)         Contributing Area:   sq mi 37973 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.
