Effects of wind and water transfer on transport of blue algal bloom in Taihu Lake

Blue algal blooms are constantly observed in Taihu Lake in recent years. Firstly, a two-dimensional hydrodynamic model and drogue tracking method are validated and possible blue algal blooms initiated at Gonghu are studied to find out how wind conditions affect blue algal blooms in Gonghu. Then, surface drogue tracking experiments are performed for blue algal blooms which are initiated at water works located in Meiliang Bay and Gonghu respectively under SE 3m/s wind condition with different water diversion measures. Finally, the results are compared and analyzed to show their efficiency on improving the water quality of the water resource areas of water works in Meiliang Bay and Gonghu.
