The effect of wave disturbance on the nutrient release from lake sediraents was simulated in flume experiments.The sediments were sampled from Lake Taihu, China, which is a large, shallow, eutrophic lake with a mean depth of 1.9 m and an area of 2447 km².The water flume was 30 m long, 0.5 m wide and 0.7 m deep.The sediments was 10 cm thick in the bottom of water flume in flume experiments.In a "little-wave" experiment, which means the wave height just a bit higher than the critical wave height for sediment resuspension, the depth of overlying water was 40 cm, the critical wave height for sediment resuspension was 8.45 cm, and the wave height for sediment resuspension experiments was 8.77 cm.In a "strong-wave" experiment,thedepthofo-verlying water was 30 cm, the critical wave height for sediment resuspension was 5.93 cm, and the wave height for sediment resuspension experiments was 12.31 cm and 13.29 cm.In the 41 little-wave.experiments, contents of suspended solids (SS) was increased to 13.6 mg/L, while in strong-wave experiments, the SS content was increased to 245.2 mg/L.The equilibrium of the con-eentration of nutrients and SS in overlying water was lag more than 1h than the change of wave height.Strong wave disturbance significantly increased the concentrations of ammonia nitrogen and soluble reactive phosphorus in overlying water.In both the little-wave experiment and strong-wave experiment, concentrations of dissolved oxygen in overlying water was increased and concentrations of dissolved organic carbon in overlying water decreased.The study indicated that strong wave might caused significant increase of internal loading of nutrients.However, flocculation and adsorption of resuspended sediments and the oxygenate action accompany by the wave disturbance may district the increasing of reactive nutrients in overlying water.
