汾河水库水温分布的现场试验

为了研究汾河水库水温的分布情况,采用WP型水温测量仪对汾河水库1#—5#断面的水温进行了3次测量,并对监测的水温数据进行了整理分析.结果表明:4月份水库水温从库表到库底基本呈等温分布,水温沿垂向变化不大,并且整个库区水温是一个完全混合状态;7月份水库水温处于一个弱分层的状态;1月份水库水温处于分层状态.实测数据可为水库水温预测模型进行参数率定以及预测结果的验证提供依据.

Field Test of Water Temperature Distribution in Fenhe Reservoir

In order to sutdy the distribution of water temperature in Fenhe Reservoir,the water temperature of Sections 1#—5# of Fenhe Reservoir was measured three times successively by means of WP-type water temperature instrument.The monitoring data of water temperature were sorted and analyzed,and the results show that the water temperature of reservoir generally presented shows an isothermal distribution from the reservoir surface to the bottom,in Aprial and the water temperature showed little change vertically.The water temperature of the whole reservoir was a completely mixed state;in July,the water temperature of reservoir was in a weekly stratification state;in January,the water temperature of the reservoir was in a stratification state.The measured data could provide evidence for the parameter calibration of the water temperature prediction model for reservoirs and also provide evidences for the verification of prediction results.
