1. What Is The Equivalent Unrefracted Deepwater Wave Height?

The Equivalent Unrefracted Deepwater Wave Height (EDWH) is a parameter used particularly in wave behaviour and breakwater design, defined in relation to the Breaker Height Index from Linear Wave Theory.

2. How Does The Calculator Work?

The calculator uses the formula:

Where:

• \( H'o \) — Equivalent Unrefracted Deepwater Wave Height (m)
• \( \lambda_o \) — Deep-Water Wavelength (m)
• \( \Omega_b \) — Breaker Height Index

Explanation: This formula calculates the equivalent unrefracted deepwater wave height based on the deep-water wavelength and breaker height index.

3. Importance Of Wave Height Calculation

Details: Accurate wave height estimation is crucial for coastal engineering, breakwater design, and understanding wave behavior in deep water conditions.

4. Using The Calculator

Tips: Enter deep-water wavelength in meters and breaker height index. Both values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the Breaker Height Index?
A: Breaker Height Index is the ratio of wave height and still water depth at the shore face location where waves start breaking.

Q2: Why is the constant 0.56 used in the formula?
A: The constant 0.56 is an empirical coefficient derived from wave theory research and experimental data.

Q3: What are typical values for Breaker Height Index?
A: Breaker Height Index typically ranges from 0.5 to 1.2, depending on wave conditions and bottom topography.

Q4: When is this calculation most useful?
A: This calculation is particularly useful in coastal engineering projects, breakwater design, and wave energy conversion systems.

Q5: Are there limitations to this formula?
A: This formula is based on linear wave theory assumptions and may have limitations in extreme wave conditions or complex bathymetry.
