The quantities of water and sediment discharged into the Huanghe River Estuary in Qingshuigou course(1976-1995) are less than those of the other three courses before 1976,and the annual and yearly variations are abundant and dry alternately,the scouring and alluviating areas of the delta are closely-related to the quantity of water-sediment into the estuary.The silting topography of the profile,the status of area growing and the alluviation distribution of the sediment discharge are analyzed,and it is found that the evolution of the Huanghe River Delta has been undergoing three period:in the primary period from 1976 to 1980 the river delta grew in a widely estuary region,in the mid-period from 1981 to 1990 the river delta grew quickly,and in the last period from 1990 to 1995 the river delta grew gently.According to the condition of water-sediment quantity in the Qinshuigou course,the areasediment analogue model is used to forecast the area growth trend of river delta in the future.
