Question

A 4 - hours unit hydrograph is in the form of a triangle as shown below

The equilibrium discharge of the $S_4$ curve would be ______m${}^3$/s.

• A. 525

Answer 1

The correct option is A 525
Area of $UH=C.A\times 0.01$

$\frac{1}{2}\times 84\times 3600\times 50=C.A\times 0.01$

$C.A=756k{m}^2$

$Q_e=2.778\frac{A}{D}$

$=2.778\times \frac{756}{4}$

$=525m^3/s$
