The distribution characteristics and evolution of the sand wave in the east of Laizhou Bay
莱州湾东部沙波地貌分布特征及其形成演化

The seabed topography survey data of Layzhou Bay were collected with multibeam sounder and echo-sounder in March,2009.Based on the bathymetric data,the distribution characteristics and the evolution of the sand waves in the area were studied.There were mainly two-dimensional linear sand wave in the study area,the wavelength of sand wave ranging from 50 m to 350 m,wave height from 0.05 m to 0.4 m,steepness from 0.0007 to 0.006,and symmetry from 0.7 to 2.3.The sand wave distribution was not only related to th...
