The found of well-defined zones of swell dominance,termed "swell pool",located in the eastern areas of the Pacific are presented in this paper,by calculating the global distribution of swell index in 2000.

The dynamic ocean surface containing swell is constructed on the basis of random ocean wave theory,and the Mapping Project Algorithm(MPA) is introduced to simulate polarimetric Synthetic Aperture Radar(SAR) images of ocean wave.

Whether the swell produced by the coffer dam falls can causes the harm to the periphery building and the environment,is always the problem people concerned.

By comparing two different directional distributions,it s shown that the directional distribution recommeded in the nowaday specifications in China is characteristic of wind wave and swell with short propagation distance and in good agreement with Mitsuyasu direction distribution.
