【Abstract】 Based on the bathymetric data of the Huanghe River mouth bar measured in 1984, 1987 and 1989, the morphological characteristics of the Huanghe River mouth bar are studied and described. The amount of erosion deposition is calculated. The laws and mechanism of formation and evolution of the mouth bar are analyzed based on the characteristics. The results provide a scientific basis for the harness of the Huanghe River Estuary sediment accumulation and for extending the lifetime of the recent Huanghe River course.更多还原
