基于Delft3D水动力模型对青草沙水库水温变化的模拟和预测OACSTPCD
Simulation and Prediction of Water Temperature Variation in Qingcaosha Reservoir Based on Delft3D Hydrodynamic Model
水体流场是影响水体温度变化的主要因素,也是影响水体污染物迁移的主要原因,这种影响在短时间内尤为明显.以上海市水源地青草沙水库为例,基于Delft3D建立模拟网格,利用ADI法进行流场数值模拟,利用实测数据进行验证得到拟合的水动力模型,并对水库的水温进行模拟,基于该模型预测未来气温条件下水库的水温变化.结果表明,随着气温的升高,水库水温高温时间段变长,升温时间点提前,未来藻类暴发时间可能不在夏季,而有所提前.
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 temperatu…查看全部>>
