Directionality and spread of shallow water waves along the eastern Arabian Sea
The directional characteristics of shallow water waves are described based on measured data during 2011 at two locations spaced at 350 km along the eastern Arabian Sea. Study shows that, for high swells (significant wave height > 1 m) approaching almost parallel to the coast, the difference b...

The directional characteristics of shallow water waves are described based on
measured data during 2011 at two locations spaced at 350 km along the
eastern Arabian Sea. Study shows that, for high swells (significant wave
height > 1 m) approaching almost parallel to the coast, the
difference between mean and principal wave direction at spectral peak is
negligible. The directional spreading of wind-sea-dominated wave spectrum is
less than that of the swell-dominated spectrum. Average value of the ratio of
the directional width at twice the peak frequency and that at the peak
frequency is 1.9 indicating that the directional width increased at higher
frequency. Even though both locations studied are along the eastern Arabian
Sea, there are more northwest waves due to shamal events and local winds found at
the northern location (27%) than at the southern
location (7%). |
