In large river basins, water management agencies are responsible for delivering flows to downstream ecosystems. In many cases, extensive dam-building has led to more stable flows, with decreased incidence and severity of high flow events. However, a growing body of research suggests floods may be ecologically important, leading to questions regarding whether flows should be managed to more closely mimic natural flood regimes. This research aims to extend beyond our current knowledge of benefits of dams in terms of water storage for industrial, municipal and agricultural purposes to assess how dams can be operated in a way to achieve positive environmental outcomes, specifically via controlled floods. This project will examine aquatic productivity and food webs following periodic, experimental inundation from a dam spillway, coupled

在大流域，水管理机构负责向下游生态系统输送流量。在许多情况下，大规模的大坝建设带来了更稳定的水流，减少了高流量事件的发生率和严重性。然而，越来越多的研究表明，洪水可能在生态上具有重要意义，这引发了以下问题：是否应该对洪水进行管理，以更接近地模拟自然洪水的状况。这项研究的目的是超越我们目前对大坝在工业、市政和农业蓄水方面的好处的了解，评估大坝如何能够以一种实现积极的环境结果的方式运行，特别是通过控制洪水。该项目将研究水生生物生产力和食物网在周期性的试验性淹没后，从大坝溢洪道，耦合
