(A) Q = C × A2/3
(B) Q = C × A3/4
(C) Q = C × An
(D) Q = C × A1/2
The Ryve’s formula to be used for flood estimation Q = C × A2/3. The study of flood flows in a river system at a specific place or over a catchment is the subject of flood estimation, a branch of hydrology science. This has historically been relied on a statistical analysis of recorded flows at gauging stations; more recently, the UK flood estimating handbook’s methodologies have been used. Alternatives include employing the QdF methodology or rainfall-runoff models to estimate design flood hydrographs.

Ryve’s Method
Only Southern India use this formula.
QP = CR × A2/3
Rational Method
This approach is based on the idea that runoff and precipitation are related. As a result, it might be compared to the empirical technique.
QP = 1/36 kPcA1
Dicken’s Method
It was once solely used in Northern India, but after the constant was properly modified, it may now be used across the majority of Indian States.
QP = CD A3/4
Inglis Method
The only place this formula is utilised is Maharashtra. Three distinct cases are considered in this instance.
QP = 124A/√A + 10.4 ≅ 123√A
where
Q = Peak discharge in m3 /s.
A = Area in km2 .
CR = CD = coefficient applicable in certain region.
6 < CD < 30
6 < CR < 11
Summary:
Which of the following is Ryve’s formula, to be used for flood estimation? (A) Q = C × A2/3 (B) Q = C × A3/4 (C) Q = C × An (D) Q = C × A1/2
The Ryve’s formula will be applied to estimate floods is Q = C × A2/3. Flood is one of the Natural disasters that affect human and animal life directly. With the help of this formula, scientists estimates the flood.
