1. What is the Seelig Equation?

The Seelig Equation is used to calculate the dimensionless coefficient for wave transmission through coastal structures. It relates the wave transmission coefficient, freeboard, and wave runup to determine the overall performance of the structure in wave energy dissipation.

2. How Does the Calculator Work?

The calculator uses the Seelig equation:

\[ C = \frac{C_t}{1 - \left(\frac{F}{R}\right)} \]

Where:

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

Explanation: The equation accounts for the relationship between wave transmission, freeboard height, and wave runup to quantify the performance of coastal structures.

3. Importance of Dimensionless Coefficient Calculation

Details: Accurate calculation of the dimensionless coefficient is crucial for designing effective coastal protection structures, predicting wave energy transmission, and ensuring structural stability in marine environments.

4. Using the Calculator

Tips: Enter wave transmission coefficient (dimensionless), freeboard in meters, and wave runup in meters. All values must be valid (Ct > 0, R > 0, and F < R).

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for the dimensionless coefficient?
A: The dimensionless coefficient typically ranges between 0.2 and 0.8, depending on the structure type and wave conditions.

Q2: How does freeboard affect the dimensionless coefficient?
A: Higher freeboard values generally result in lower wave transmission and thus affect the dimensionless coefficient calculation.

Q3: When should this equation be used?
A: This equation is particularly useful for designing and analyzing rubble mound breakwaters and other coastal protection structures.

Q4: Are there limitations to this equation?
A: The equation may be less accurate for structures with complex geometries or under extreme wave conditions.

Q5: What units should be used for input values?
A: Freeboard and wave runup should be in meters, while the wave transmission coefficient is dimensionless.
