- Abstract
To research the water temperature cumulative effect of the power station cascade development, taking the upper reaches of the Yellow River from Ningmute to Maerdang as an example. In the paper, the water temperature impact evaluating indicator was used, combined with three-dimensional model to simulate the distribution of the reservoir area water temperature in its six work conditions. The water temperature affect characteristics of the Maerdang reservoir was reflected intuitively and clearly. When the Maerdang reservoir run separately, the effects of water temperature was small than jointly run. The minimize of the water temperature effect is the separately run wet years condition, while the maximum is jointly run dry year conditions. The baseline deviation from the indicators can intuitively reflect the Maerdang reservoir from month to month, the heating and cooling season and year-round water temperature deviate characteristics. The phase deviation indicators precisely water temperature hysteretic effect. The extremal change indicator vividly describes the effect of water temperature planarizing effect. The application of evaluation indicator can provide a scientific basis for the rational development and utilization of the period for river, reservoir optimal scheduling.
