Download Solution PDFExplanation:
Dicken’s Method
It was adopted for Northern India.
\(Q_P=C_DA^{\frac{3}{4}}\)
Where:
-
Q_P = Peak discharge in m³/s -
A = Area in km² -
= Coefficient applicable in the region
Additional InformationDifferent empirical methods for determining flood discharge are as follows:
Ryve’s Method: \(Q_P=C_DA^{\frac{2}{3}}\)
This formula is used only in Southern India.
Jarvi’s Method: \(Q_P=C_D\sqrt A\)
This formula is applicable for Eastern India.
