Flow regime meaning
WebJan 1, 2024 · The flow regime of a river is defined as the temporal variability of its discharge, particularly the quantity, timing, and variability in flow (Poff et al., 1997, Nilsson and Renöfält, 2008, Sauquet et al., 2008).Flow regimes are generally expressed as statistical generalizations of hydrological phenomena (e.g., seasonal runoff patterns, … WebFlow Regime. From a practical engineering point of view, the flow regime can be categorized according to several criteria. All fluid flow is classified into one of two broad categories or regimes. These two flow regimes are: Single-phase Fluid Flow. Multi-phase Fluid Flow (or Two-phase Fluid Flow) This is a basic classification.
