Breaker Height Index Solution

STEP 0: Pre-Calculation Summary

Formula Used

Breaker Height Index = Wave Height at Incipient Breaking/Deep-Water Wavelength
Ω_b = H_b/λ_o
This formula uses 3 Variables

Variables Used

Breaker Height Index - Breaker Height Index is the ratio of wave height and still water depth at the shore face location where waves start breaking.
Wave Height at Incipient Breaking - (Measured in Meter) - Wave Height at Incipient Breaking refers to the height of the wave at the point where it starts breaking, often referred to as the breaker point.
Deep-Water Wavelength - (Measured in Meter) - Deep-Water Wavelength is the horizontal distance between two successive crests (or troughs) of the wave.

STEP 1: Convert Input(s) to Base Unit

Wave Height at Incipient Breaking: 18 Meter --> 18 Meter No Conversion Required
Deep-Water Wavelength: 7 Meter --> 7 Meter No Conversion Required

STEP 2: Evaluate Formula

Substituting Input Values in Formula

Ω_b = H_b/λ_o --> 18/7

Evaluating ... ...

Ω_b = 2.57142857142857

STEP 3: Convert Result to Output's Unit

2.57142857142857 --> No Conversion Required

FINAL ANSWER

2.57142857142857 ≈ 2.571429 <-- Breaker Height Index

What is Wave Period?

The Wave Period is the time it takes to complete one cycle. The standard unit of a wave period is in seconds, and it is inversely proportional to the frequency of a wave, which is the number of cycles of waves that occur in one second. In other words, the higher the frequency of a wave, the lower the wave period.

What is Breaker Index?

The Breaker Index is defined as the ratio between the height of a wave and the water depth in which the wave breaks or the ratio of wave height and still water depth at the shoreface location where waves start breaking.
