1. What is Wave Height?

Wave Height is the vertical distance between the crest and the trough of a wave. Higher wave heights correspond to greater wave forces, which leads to increased structural loading in marine environments.

2. How Does the Calculator Work?

The calculator uses the wave height formula:

\[ H = \sqrt{\frac{KE}{\frac{1}{16} \times \rho \times g \times \lambda}} \]

Where:

\( H \) — Wave Height (m)
\( KE \) — Kinetic Energy of Wave Crest (J)
\( \rho \) — Mass Density (kg/m³)
\( g \) — Gravitational acceleration (9.80665 m/s²)
\( \lambda \) — Wavelength (m)

Explanation: This formula calculates wave height based on the kinetic energy of the wave crest, mass density of water, gravitational acceleration, and wavelength of the wave.

3. Importance of Wave Height Calculation

Details: Accurate wave height estimation is crucial for coastal engineering, offshore structure design, navigation safety, and understanding wave energy distribution in marine environments.

4. Using the Calculator

Tips: Enter kinetic energy in joules, mass density in kg/m³, and wavelength in meters. All values must be positive numbers greater than zero.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range of wave heights in oceans?
A: Wave heights can range from a few centimeters (ripples) to over 30 meters in extreme storm conditions, with most ocean waves between 1-5 meters.

Q2: How does wave height affect coastal structures?
A: Higher wave heights generate greater hydrodynamic forces that can cause erosion, structural damage, and overtopping of coastal defenses.

Q3: What factors influence wave height besides kinetic energy?
A: Wind speed, duration, fetch length, water depth, and seabed topography all significantly influence wave height development.

Q4: How is wave height measured in practice?
A: Wave height can be measured using buoys, satellite altimetry, radar systems, or visual observations from ships and platforms.

Q5: What are the limitations of this calculation method?
A: This formula assumes ideal wave conditions and may not account for complex wave interactions, breaking waves, or shallow water effects.
