Question

What is the maximum flood flow by using Inglis formula for a catchment in Western Ghat in Maharashtra having an area of $38.6k{m}^2$?

• A. $518.83m^3/sec$
• B. $601.18m^3/sec$
• C. $683.77m^3/sec$
• D. $952.93m^3/sec$

Answer 1

The correct option is C $683.77m^3/sec$

By Inglis formula,
$Q_p=\frac{124A}{\sqrt{A+10.4}}$

$Q_p=\frac{124\times 38.6}{\sqrt{38.6+10.4}}=683.77m^3/sec$
