1. What is Wave Runup Above Mean Water Level?

Wave Runup is the maximum onshore elevation reached by waves, relative to the shoreline position in the absence of waves. It's 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:

\[ R = \frac{F}{1 - \frac{C_t}{C}} \]

Where:

\( R \) — Wave Runup (m)
\( F \) — Freeboard (m)
\( C_t \) — Wave Transmission Coefficient
\( C \) — Dimensionless Coefficient in the Seelig Equation

Explanation: This formula calculates the wave runup height above mean water level based on freeboard height and wave transmission characteristics through coastal structures.

3. Importance of Wave Runup Calculation

Details: Accurate wave runup estimation is crucial for designing coastal protection structures, determining safe elevation levels for coastal development, and assessing flood risks in coastal areas.

4. Using the Calculator

Tips: Enter freeboard in meters, wave transmission coefficient (dimensionless value between 0-1), and dimensionless coefficient from the Seelig equation. All values must be valid (freeboard > 0, C > Ct).

5. Frequently Asked Questions (FAQ)

Q1: What is freeboard in coastal engineering?
A: Freeboard is the height of the watertight portion of a building or other construction above a given level of water, providing a safety margin against wave overtopping and flooding.

Q2: What does the wave transmission coefficient represent?
A: The wave transmission coefficient is a dimensionless ratio that quantifies the amount of wave energy transmitted through a structure compared to the incident wave energy.

Q3: What are typical values for the Seelig equation coefficient?
A: The dimensionless coefficient in the Seelig equation typically ranges between 0.3-0.6 for various coastal structures, depending on material properties and structural configuration.

Q4: When is this calculation most important?
A: This calculation is particularly important for designing breakwaters, seawalls, and other coastal protection structures where wave energy transmission and runup affect structural integrity and safety.

Q5: Are there limitations to this equation?
A: This equation provides an estimation and may need adjustment for complex coastal geometries, irregular wave conditions, or structures with unusual material properties.
