Dicken’s Method
It was adopted for Northern India.
\({Q_P} = {C_D}{A^{\frac{3}{4}}}\)
where
QP = Peak discharge in m3/s.
A = Area in km2.
CD = coefficient applicable in the region.
Additional Information
Different empirical method for determining flood discharge are as follows:
Ryve’s Method
\({Q_P} = {C_R}{A^{\frac{2}{3}}}\)
This formula is used only in Southern India.
Jarvi’s Method
This formula is applicable for Eastern India.
\({Q_P} = C\sqrt A\)
Inglis Method
This formula is used only in Maharashtra. Here three different cases are taken into consideration.
\({Q_P} = \frac{{124A}}{{\sqrt {A + 10.4} }} \cong 123\sqrt A \)
