1. What is the Effect of Current on Wave Height?

The effect of current on wave height describes how water currents influence the height of waves as they enter an inlet. The inlet current wave height factor (R_h) represents the ratio between the actual wave height and the wave height entering the inlet.

2. How Does the Calculator Work?

The calculator uses the formula:

\[ H = R_h \times H_A \]

Where:

\( H \) — Wave Height (meters)
\( R_h \) — Inlet Current Wave Height Factor (dimensionless)
\( H_A \) — Wave Height Entering Inlet (meters)

Explanation: This formula calculates the actual wave height by multiplying the wave height entering the inlet by the current's effect factor.

3. Importance of Wave Height Calculation

Details: Accurate wave height calculation is crucial for coastal engineering, navigation safety, port operations, and understanding coastal erosion processes.

4. Using the Calculator

Tips: Enter the inlet current wave height factor (dimensionless value between 0-1 typically) and the wave height entering the inlet in meters. Both values must be positive numbers.

5. Frequently Asked Questions (FAQ)

Q1: What is the typical range for the inlet current wave height factor?
A: The factor typically ranges from 0 to 1, where 1 indicates no reduction in wave height and lower values indicate greater current-induced wave height reduction.

Q2: How does current affect wave height?
A: Currents can either amplify or reduce wave height depending on whether the current is following or opposing the wave direction.

Q3: When is this calculation most important?
A: This calculation is particularly important for harbor design, navigation channel safety, and coastal structure design.

Q4: Are there limitations to this simplified formula?
A: Yes, this is a simplified approach. More complex models may be needed for precise engineering applications that consider wave-current interaction dynamics.

Q5: Can currents increase wave height?
A: Yes, following currents (currents moving in the same direction as waves) can actually increase wave height, while opposing currents typically decrease wave height.
