1. What is Energy Dissipation Rate?

Energy Dissipation Rate per unit Surface Area is the amount of energy lost by the viscous forces per unit surface area. It quantifies the rate at which wave energy is dissipated due to wave breaking and other processes.

2. How Does the Calculator Work?

The calculator uses the energy dissipation formula:

\[ \delta = \frac{K_d}{d} \times ((E'' \times C_g) - E_f) \]

Where:

\( \delta \) — Energy Dissipation Rate per unit Surface Area
\( K_d \) — Decay Coefficient
\( d \) — Water Depth (m)
\( E'' \) — Wave Energy (J/m²)
\( C_g \) — Wave Group Speed (m/s)
\( E_f \) — Energy Flux associated with Stable Wave Height

Explanation: The equation calculates the rate of energy dissipation by considering the decay coefficient, water depth, wave energy, wave group speed, and energy flux.

3. Importance of Energy Dissipation Calculation

Details: Accurate energy dissipation calculation is crucial for understanding wave behavior, coastal erosion patterns, and designing coastal protection structures.

4. Using the Calculator

Tips: Enter all required values with appropriate units. Ensure all values are positive and water depth is greater than zero for valid calculations.
