Technical Note |
| Abstract: |
The purpose of this technical note is to present a new formula to compute the incipient breaking wave properties based on a simplified solution of the wave energy flux conservation equation combined with Snell’s law. The execution time and calculated results of the new formula were compared with those of the iterative method which is commonly used in coastal engineering calculations, including in shoreline response modeling. The new formula could be used instead of the iterative method to save calculation time for application in coastal engineering. |
