What is Wave Reflection on Structures?

If there is a change in water depth as a wave propagates forward, a portion of the wave’s energy will be reflected. When a wave hits a vertical, impermeable, rigid surface-piercing wall, essentially all of the wave energy will reflect from the wall. On the other hand, when a wave propagates over a small bottom slope, only a very small portion of the energy will be reflected. The degree of wave reflection is defined by the reflection coefficient Cr = Hr/Hi where Hr and Hi are the reflected and incident wave heights, respectively.

How to Calculate Reflection Coefficient in Coastal Structures?

Reflection Coefficient in Coastal Structures calculator uses Reflection Coefficient = (Coefficient 'a'*Surf Similarity Number (Iribarren Number)^2)/Coefficient 'b'+Surf Similarity Number (Iribarren Number)^2 to calculate the Reflection Coefficient, The Reflection Coefficient in Coastal Structures formula is defined as the ratio of the reflected wave height to the incident wave height when waves encounter a structure such as a breakwater, seawall, or any coastal defense structure. Reflection Coefficient is denoted by r symbol.
