Sand waves in the Daishan Houshayang of the Zhoushan Islands were surveyed with multibeam sounding system and subbottom profiler. Results show that, 1) bedforms are distributed in the zones of shore slope, sand ridge, gentle slope, trench and flat bed seawards from the coast; 2) sand waves are mainly developed in the gentle slope zone, the south and east to the sand ridge zone, the north of the trench and the slopes between small trenches; 3) sand waves are usually distributed in relatively flat terrain within a depth of 10m to 21.1m on a slope less than 0.09 degree to 2.8 degree; 4) sand waves can be divided into small, medium and large ones in a zone. 5) sand waves move actively under the action of tidal current.
