15 (a) Shoaling analysis shall be based on linear wave theory (also known as Airy wave theory). (b) Refraction analysis shall be based on Snell's law assuming that the seabed contours are parallel with the direction of travel of the Vessel and that the angle between the wave crest and the seabed contours in very deep water is 55°. (c) In order to allow for non-linear effects, an effective water depth of D + ½H, where D is the average water depth and H is the wave height, shall be adopted in the shoaling and refraction analysis where appropriate. (d) The effects of bottom friction, viscous effects and turbulence shall be ignored in any shoaling and refraction analysis. (e) No adjustments shall be made to the Wave Periods assessed at the measurement site. E. Physical Parameters For the purposes of any calculation to assess wave characteristics under this Bylaw: (a) The density of sea water shall be taken as 1025 kg/m; 3 (b) The kinematic viscosity of sea water shall be taken as 1.15 10 6 m/s; 2 (c) The acceleration due to gravity shall be taken as 9.806 m/s; and 2 (d) Other physical parameter values shall be that applicable at a temperature of 15°C.
