东风水库下游临岸潜流带水流场响应规律研究

Water Flow Field Response Regularity Research of the Near Shore Undercurrent Zone at Dongfeng Reservoir Downstream

水库下游临岸潜流带水流场响应规律可用于预测不同水库运行情景下临岸潜流带的水头与流量变化情况。本文以复州河东风水库为例,基于测量数据得到其下游某断面临岸潜流带的水头及流量响应过程,提出响应强度指标的概念,得到简单直观的响应规律经验公式,从而为该水库下游临岸系统的生态建设提供依据,并为水库运行方案的生态影响评价提供参考。

Water flow field response regularity of near shore undercurrent zone at reservoir downstream can be used to forecast the changing condition of delivery head and flow rate in different reservoir operation circumstances. The article takes Fuzhou River Dongfeng Reservoir as an example,get the delivery head and flow rate response process of its downstream near shore undercurrent zone on the basis of measured data,put forward concept of response intensity index,get simple and visual response regularity empirical formula,thereby provide the basis for the ecological construction of the reservoir downstream near shore system and provide reference for ecological impact assessment of the reservoir operation scheme.
