Abstract

Abstract Controlled in-stream flow manipulations are challenging but necessary to implement to assess the consequences of real-world flow alterations on aquatic ecosystems. We designed a double v-notch weir system, which was first prototype-tested in a laboratory flume and then in the field. The device diverted instantaneous flows proportionally in a robust way (e.g., 10% of flow in the stream main channel and 90% of flow into the diversion channel). We tested diversions systematically and evaluated how well flows matched our target flow-percentages. This is one of the first ecohydraulic structures designed and tested to experimentally manipulate environmental flows in small upland streams.

溪流环境流量实验操纵的成对堰系统设计
控制流内流量是评估现实世界流量变化对水生生态系统影响的一项挑战。我们设计了一个双v形槽堰系统,首先在实验室水槽中进行了原型测试,然后在现场进行了测试。该装置以稳健的方式按比例分流瞬时流量(例如,10%的流量进入溪流主河道,90%的流量进入导流通道)。我们系统地测试了改道,并评估了井流量与目标流量百分比的匹配程度。这是第一个设计和测试的生态水力结构之一,用于实验控制小型高地溪流的环境流动。
