River ecosystems are four-dimensional systems, with longitudinal, lateral, and vertical components, relationships, and processes; temporal vectors add the fourth dimension. The overriding importance of dynamic flow patterns in streams and rivers is captured in the Natural Flow Regime Paradigm. More general hydro-ecological principles conceptualise and quantify the ecological roles of flow, and contribute to the understanding of the flow requirements of rivers and their biota. Explicit hydro-ecological principles and conceptual models describe in-stream biodiversity (aquatic plants, invertebrates, and fish), riparian vegetation, and nitrogen dynamics. Although common to most stream and river ecosystems, particulars vary with climate, biogeographic region, topography, catchment vegetation, and flow regime type. Hydro-ecological principles and concepts described in this chapter provide the ecological foundations for environmental flow management.
