Based on the investigation of the strength characteristics of seabed in front of a bank and nearby area in a section scale

the dynamic response of silt seabed was studied in the Yellow River estuary beach.It was found that the relative hard strata not only formed horizontally but also vertically;and the vertical stratum has a relationship to the hydrodynamics.Through the impact loading and model analysis

a conclusion is drawn as follows: the formation of seabed sediment consolidated inhomogeneity is due to the fine particles flow under wave loading

when the fine particles accumulate

the sediments will become harder for the perspiration of pore water pressure;thus result in the inhomogeneity of silt seabed.
