1. What is Deepwater Wave Height?

Deepwater Wave Height refers to the measurement of the vertical distance between the trough and the crest of a wave in deep water. It is a crucial parameter in coastal engineering and oceanography for understanding wave behavior and its impact on coastal structures.

2. How Does the Calculator Work?

The calculator uses the formula:

Where:

• \( H_d \) — Deepwater Wave Height (m)
• \( R' \) — Mean Runup (m)
• \( \varepsilon_0 \) — Deepwater Surf Similarity Parameter (-)

Explanation: This formula calculates the deepwater wave height based on the mean runup and deepwater surf similarity parameter, which compares the wave surface slope to the bed slope in the surf zone.

3. Importance of Deepwater Wave Height Calculation

Details: Accurate calculation of deepwater wave height is essential for coastal structure design, beach erosion studies, and understanding wave energy distribution in marine environments.

4. Using the Calculator

Tips: Enter mean runup in meters and deepwater surf similarity parameter (dimensionless). Both values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the significance of the surf similarity parameter?
A: The surf similarity parameter represents important features of the hydrodynamics of the surf zone and helps characterize wave breaking types and patterns.

Q2: How accurate is this calculation method?
A: This empirical formula provides good estimates for typical coastal conditions but may have limitations in extreme wave conditions or complex bathymetry.

Q3: What are typical values for deepwater wave height?
A: Deepwater wave heights can range from less than 1 meter in calm conditions to over 20 meters during severe storms.

Q4: How does mean runup affect deepwater wave height?
A: Higher mean runup values generally correspond to larger deepwater wave heights, as more wave energy is being transferred to the shoreline.

Q5: Are there limitations to this equation?
A: This formula is most accurate for specific coastal conditions and may need adjustment for unusual beach slopes, complex wave patterns, or non-uniform bathymetry.
