24 TECHNICAL MANUAL

Obtain the weighted discharges at the gage:

QIO = 5,070 ft3/s
Qso =13,100 ft3/s
Q100=18,400 ft3/s
Qsoo=36.000 ft3/s

Compute discharges at ungaged site:

QIO =(132fI69)0.48( 5,070 ft3/s)=0.89( 5,070)= 4,510 ft3/s
Qso =(132fI69)0.48(13,100 ft3/s)=O,89(13.100)=II,700 ft3/s
Qloo=(132fI69)0.48(18,400 ft3/s)=0.89(18,400)=16.400 ft3/s
Qsoo=(132f169)0.48(36,OOO ft3/s)=0.89(36,000)=32.000 ft3/s
