* Refraction coefficient, Kj, — Vb / b at design water level. 

 Shoaling coefficient, K = H / H at design water level. 



t Adopted as the significant design wave height. 



NOTES 



Columns 1, 2 and 3 are taken from the statistical wave data as determined from synoptic weather 

 charts. 



Column 4 is determined from the relative distances between two adjacent orthogonals in deep 

 water and shallow water, and the shoaling coefficient. 



Column 5 is the product of columns 2 and 4.
