【Abstract】 Accoding to large amount of survey date, the hydrometeorologic features in the Pulandian Bay are analysesed and the relations between the primary hydr- ometeorologic factor and the movement of silt are emphatically discussed. The northeastern wind and the southwestern wind,by the movement power of sea water,play an important role in the movement of silt in the bay.In the bay, the force to stir silt comes out of wave;the force to transport silt comes out of tidal current along deep waterways,tidal current and wave current in the shallows. The direction along which silt is transported is controlled by tidal currents.The silt in the bay comes primarily from rivers and the erosion of sea shore and islands,a part of silt is provided by out sea.更多还原
