By BYJU'S Exam Prep

Updated on: October 17th, 2023 (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.
