Abstract
Flow field of water body is the main factor affecting water temperature variation,and it is also the main reason for the migration of water pollutants.This effect is quietly obvious in a short time period.In this paper,Qingcaosha Reservoir in Shanghai is used as an example.Based on Delft3D,the simulation grid is established and the numerical simulation of flow field is carried out by ADI.The hydrodynamic model is verified by the measured data.Water temperature of the reservoir is simulated.Based on the model,water temperature of the reservoir is predicted in future.The results show that the reservoir water temperature will increase in future and the period of high temperature will be longer and in advance.The number of algae will increase not in summer but in advance.关键词
