Identifying flood- and food-related limits to fish and wildlife production in the Saskatchewan River delta

在大型河流流域，水管理机构负责向下游生态系统输送水流。在许多情况下，大规模的水坝建设导致了更稳定的水流，降低了高流量事件的发生率和严重程度。然而，越来越多的研究表明，洪水可能具有重要的生态意义，这引发了一个问题，即是否应该更接近地模拟自然洪水制度来管理流量。这项研究的目的是超越我们目前对水坝在工业、市政和农业储水方面的好处的了解，评估水坝如何以一种方式运作，以实现积极的环境成果，特别是通过控制洪水。该项目将研究周期性的、实验性的大坝溢洪道淹没后的水生生产力和食物网

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
