Critical river length calculation method for reservoir discharge water temperature influence recovery
The invention discloses a critical river length calculation method for reservoir discharge water temperature influence recovery, and the method comprises the following steps: 1, building a longitudinal one-dimensional mathematical model of a river reach under a dam, and obtaining the on-way water temperature change of a downstream river reach; compared with the natural water temperature before the reservoir is built, the critical river length for recovering the natural water temperature is obtained; and 2, according to the critical river length, the net heat flux and the water temperature rising and falling amplitude, a multiple regression method is adopted for fitting to obtain a critical river length formula of reservoir discharged low-temperature water and discharged high-temperature water recovered along the way under the dam. The critical river length calculation method for reservoir discharge water temperature influence recovery is wide in application range, easy and convenient to operate and high in reliability, and water temperature ecological risks under different scales of hydropower engineering dams can be judged on the basis.
本发明公开了一种水库下泄水温影响恢复的临界河长计算方法，包括以下步骤：步骤1：建立坝下河段纵向一维数学模型，得到下游河段沿程水温变化；与水库建成前沿程天然水温相比，得到恢复至天然水温的临界河长；步骤2：根据临界河长、净热通量以及水温升降幅采用多元回归方法拟合得到水库下泄低温水和下泄高温水在坝下沿程恢复的临界河长公式。本发明要解决的技术问题是提供一种适用范围广、操作简便、可靠性高的水库下泄水温影响恢复的临界河长计算方法，更能有依据地判断不同规模水电工程坝下水温生态风险。
