摘要：A three dimensional model of simplified riverine estuary was established with numerical simulation to investigate the distribution of estuarine salinity and suspended sediment under different flow rates. The spatial distribution of suspended sediment and deposition in the simulation were inspected.(1)There are two types of vertical distribution of suspended sediment, one increasing with water depth all the way and the other beginning with increasing and then followed by decreasing.(2)The head of salt wedge where the turbidity maxima is formed contributes to a large number of sediment deposition on bed;(3)With the increase of flow rates, saltwater intrusion is weakened, the corresponding turbidity maximum zone and the location of rapid sedimentation both moved toward the sea.(4)The estuarine circulation dominates the major processes of the turbidity and deposition at the salt front.
