黄河三角洲滨海区流场分布及泥沙运动

DISTRIBUTION OF FLOW FEILD AND SILT MOVEMENT IN THE COASTAL AREAS OF THE HUANGHE RIVER DELTA

本文通过多年的海流及地形观测资料,分析研究了黄河三角洲滨海区的流场分布及泥沙运动规律,认为现行黄河口区是泥沙直接沉积区,而在海洋动力要素作用下,泥沙沉积再搬运后沿岸作长距离的输移运动,使泥沙重新分布,也是海岸带开发利用、水工建筑等不可忽视的研究课题。

Onthe basis of many years of observational data on ocean currents and topography,analyis and study was made of the distrelation of flow field and the regular patterns of silt movement in the coastal areas of the Huanghe River delta.It is beleived that the prosent Huanghe River mouth area is an area formed from direct sedimentationof silt,and that under the actions of the marine dynamic parameters,the retransported silt deposit undergoes a long-distance trancport along the coast,this resultingin re-distribution of the silt deposit.This is also a research project not to be ignored in the ex- ploitation and ectilization of the coastal zone and in hydraulic construc- tion.
