摘要
采用二维模型CE-QUAL-W2对青岛市王圈水库进行水温数值模拟,运用库区的实测资料对模型进行校正,并分析研究了出水口高程对水库水温分层的影响。研究结果表明:3月份水库垂向水温分布均匀,到5月份逐渐开始分层,温跃层形成于8月,9月份以后水温分层消失;随着出水口高程升高,水库上层水体温度变化不大,而下层水体水温下降,水库温跃层厚度增加。
Two dimensional water quality model, CE-QUAL-W2, was applied to simulate the water temperature in Wangquan Reservoir. The model was calibrated by the observation data from the reservoir, and the influence of outflow elevation on water temperature stratification was analyzed. The results showed that the vertical distribution of water temperature was homogeneous,the march thermal stratification of the water body gradually started occurring in May. The thermoeline in was developed in early August. After September the water temperature stratification gradually disappeared. The temperature of the epilimnion did not change significantly with increasing outflow elevation. However, the temperature of hypolimnion decreased, resulting in an increase in the thermocline depth of the reservoir.
