WebJun 7, 2024 · Abundant research around the natural flow regime concept (Poff et al., 1997) has explored the link between the different facets of flow regime (i.e., magnitude, frequency, duration, and timing of high- and low-flow events) and the provision of ecological outcomes (e.g., persistence of native freshwater biodiversity).
