Determination of Sediment Depositional Range in HuangMao Bay

The main courses of sediment transport in Huang Mao bay are obtained by the relationship which is calculated by the fuzzy mathematical theory and cluster of the samples data determined by neutron activation method.The samples as sediment sources are selected based on actual conditions and analysis of sediment so urces characteristics.And the sediment depositional range from each source can be determined by the least-squares method.
