1. What is Wave Runup?

Wave Runup is the maximum onshore elevation reached by waves, relative to the shoreline position in the absence of waves. It is a critical parameter in coastal engineering for designing coastal structures and assessing flood risks.

2. How Does the Calculator Work?

The calculator uses the Wave Runup formula:

Where:

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

Explanation: This formula calculates the maximum wave runup based on deepwater wave characteristics and surf similarity parameters.

3. Importance of Wave Runup Calculation

Details: Accurate wave runup estimation is crucial for coastal structure design, flood risk assessment, and shoreline management planning.

4. Using the Calculator

Tips: Enter deepwater wave height in meters and deepwater surf similarity parameter. All values must be valid positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What factors influence wave runup?
A: Wave runup is influenced by wave height, wave period, beach slope, and surface roughness of the coastal structure.

Q2: How accurate is this formula?
A: This empirical formula provides reasonable estimates for many coastal conditions but may need adjustment for specific site characteristics.

Q3: When is wave runup measurement important?
A: Wave runup is critical for designing coastal protection structures, determining setback lines, and assessing coastal flood risks.

Q4: Are there limitations to this equation?
A: The formula may be less accurate for very steep or very flat beaches, and for complex coastal geometries.

Q5: Can this be used for all types of waves?
A: This formula is primarily designed for wind-generated waves in coastal environments and may not be suitable for tsunamis or other extreme wave events.
