Abstract

We developed a model for algal growth simulation considering flow disturbance, temperature, light intensity and nutrient concentration. Jinshan Lake, a typical river-connect lake at the middle-lower reaches of the Yangtze River, was selected as the research area. According to the simulations on the algal growth processes under the different hydrodynamic conditions of typical water years in Jinshan Lake, we found that: the highest algal concentration values mainly concentrated in July and August of the three typical years. In low water year the days with high algal concentration lasted longer than that in other years for the poor water exchange frequency. Due to the uneven-distributed dynamic conditions, the water surfaces of high algal concentration in the high water year, common water year and low water year were respectively 0.15 km2, 0.91 km2 and 1.26 km2.
