In the late 1960s in North America, the River Continuum Concept (RCC)—an ecosystem perspective of the rivers—emerged [32]. The RCC generated numerous studies many of that supported it, others disproved it, and yet others offered many modifications [58,65]. Studies of large river systems, which develop extensive floodplains, brought into focus the importance of the lateral interaction with the floodplains and their linkages with riverine fisheries [73]. Detailed studies of the floodplains of large rivers resulted in the flood pulse concept (FPC). The FPC thus added the perspective of lateral connectivity to the longitudinal connectivity of the riverine ecosystem [21].
Adaptive water management in response to climate change: the case of the southern Murray darling Basin
Published in Australasian Journal of Water Resources, 2023
Increasingly the world’s major river systems are subject to intensive management of flows for energy generation, flood management and water supply (Vörösmarty et al. 2010). The use of environmental flows or ‘e-flows’ to mitigate against the ecological impacts of altered flow has been a feature of river management over the last two decades (Arthington et al. 2018). Key theories within riverine ecology have recognised flow as a ‘master driver’ within river ecosystems. The science of restoring flow has developed on the foundation of the natural flow paradigm (Poff et al. 1997). These foundations have improved our understanding of the relationship between attributes of the flow regime and ecological responses to natural variability and to flow alteration (Poff 2018). Insights from the River Continuum Concept (Vannote et al. 1980), Flood Pulse Concept (Junk, Bayley, and Sparks 1989), Riverine Ecosystem Synthesis (Thorp, Thoms, and Delong 2006) and the River Wave Concept (Humphries, Keckeis, and Finlayson 2014) have provided an increasingly nuanced conceptualisation of the relationship between flow and ecological outcomes.
