【摘要】 采用一维水量水温耦合模型模拟预测拟建梯级水库坝址水温分布规律。充分考虑了流量、流速、气温、辐射等影响因素。利用直门达站和岗拖站实测资料进行验证,计算结果与实测资料吻合较好。根据验证的模型对不同典型年的坝址水温预测,结果很好地反应了计算江段的水温随时间、空间的变化规律。研究成果能够为无实测资料的水库坝址进行各种分析计算提供很好的试验资料。更多还原

【Abstract】 This paper simulates and forecasts the natural water temperature of the planned reservoir dam site in the Jinshajiang River upstream section which is based on the one-dimensional water quality and temperature coupling model and which fully considers the runoff,the velocity of flow,air temperature,radicalization and so on.Verified by utilizing the testing data of Zhimenda Station and Gangtuo Station,the calculation results are close to the real data.According to the confirmed model,using the hydrological data and weather data forcast the water temperature of different typical year at the reservoir dam site,the result showed the tempreature as the space and time changed at the calculated river.The research results would be helpful to each kind of analysis computation for reservoir dam site which lacks actual data.更多还原
