Based on the principle of conservative matter removal in estuary, a new method is proposed for estimating the ratio of sediment resuspension in estuaries with fine-suspended sediments. Nearly half of the particulate matter in the turbidity maximum zone (TMZ) of the Changjiang (Yangtze) estuary originates from sediment resuspension, indicating that sediment resuspension is one of the major mechanisms involved in formation of the TMZ. Compared with traditional method for calculating these ratios in the estuary, this new method evaluates the dynamic variation of SPM content carried by river runoff from the river mouth to the ocean. The new method produced more reliable results than the traditional one and could produce a better estimation of resuspension flux for particulate matter in estuaries.
