Concerns on ecological effects of sediment resuspension are on the rise because the sediments in shallow lakes are frequently disturbed by winds. However, few methods could be suitable for supporting its related study. In this paper, Y-shape apparatus for simulating sediment resuspension was used to study vertical distribution of suspended sediments in water column and their total suspended amounts driving by different wind speed in Chang-dougang Harbor, southern Lake Taihu. The results showed that the relationship between the total suspended amount of sediments in water column (T) and the motor rotation frequency(n) could be expressed byT=19.77 exp(n/2.61)-71.7. Based on the total suspended amounts in water column under field wind conditions, quantitative relationships were achieved among the simulated hydrodynamic conditions, the total suspended amounts of sediments and the field wind conditions. According to the correspondent frequency of motor rotation to field wind speed in Lake Taihu from October 2004 to October 2005, the total suspended amounts of sediments were estimated at 159, 230 and 425 g/m² for field light, moderate and strong winds, respectively. The estimated amounts, together with the vertical distribution of suspended sediments in water column, were consistent with those observed under field conditions. The Y-shape apparatus was thus recommended for use in studying the ecological effects of sediment resuspension in shallow aqueous system.
