摘要
棘洪滩水库的源水是水库流场变化的主要动力,风力状况也是影响棘洪滩水库流场况变化的重要因素,当水库处于非调水期,风力状况的作用尤为明显。本论文整理了棘洪滩水库1989～2008年20年间气象资料,统计得出水库年际和四个季度的风向、风力变化情况。结果表明,棘洪滩水库常年盛行风向是南风和西北风。春季和冬季以西北风为主,夏季和秋季以东风和东南风为主。通过SMS软件建立的水质模型可以验证,不同的风向与风力大小对水库流场的变化有着显著的影响。
The source water of Jihongtan Reservoir is the main impetus for the flow field variation. The wind conditions are also important influencing factor for reservoir flow field. Its influence is more obvious under the condition of non-transfer period. Through the collected meteorological data of Jihongtan Reservoir in 20 years from 1989 to 2008, the annual and 4 quarter wind intensity and direction variations had been obtained. The results showed that the predominant direction of wind was mainly souther and northwester all though the year. Northwest wind mainly appeared in spring and winter, east and southeast winds mainly appeared in summer and autumn. The water quality models established by the SMS software can verify that different wind directions and wind power have significant impacts on the changes of reservoir flow field.
