wavevel2wlconvfactor

[Kuv, f] = wavevel2wlconvfactor(f, h, heightfrombed, kCalcMethod, dispout)

Description

Calculate a water particle horizontal orbital velocity to the water surface elevation conversion factor

Inputs

f

Frequency in (Hz)

h

Water depth in (m)

heightfrombed

Height from bed that Kp calculated at in (m)

kCalcMethod=’beji’;

Wave number calculation method

‘hunt’: Hunt (1979), ‘beji’: Beji (2013), ‘vatankhah’: Vatankhah and Aghashariatmadari (2013)

‘goda’: Goda (2010), ‘exact’: calculate exact value

dispout=’no’;

Define to display outputs or not (‘yes’: display, ‘no’: not display)

Note: inputs can be as a single value or a 1-D vertical array

Outputs

Kuv

Horizontal orbital velocity to the water surface elevation conversion factor

f

Frequency (Hz)

Examples

[Kuv,f]=wavevel2wlconvfactor(0.2,1,0.2,'beji','no');

[Kuv,f]=wavevel2wlconvfactor([0.2;0.25],[0.5;0.6],0.2,'exact','yes');
