Youghiogheny Flow at the Tailrace

The flow in the Youghiogheny River just upstream of the tailrace is estimated by the following equation (Ref.1, p.3-5):"

• QF = 0.8 * (2.275 * Q^0.964)
• QF = Discharge at Friendsville (cfs)
• Q = Discharge at Oakland (cfs)
• Q_dc = 0.8 * QF
• Q_dc = Discharge Below Tailrace (cfs)

The flows at Oakland and Friendsville are obtained from USGS flow gages, stations #03075500 and #03076500 respectively. (Note that a different equation is proposed in Ref.1, p.4-33, namely Q_dc = 1.68 * Q_o^0.97) See Also Ref.1, Appendix B of Appendix G

A graph showing the difference between these two relations is found here.
