Short summary
Rainfall-runoff event identification can be highly affected by parameter-driven uncertainty and event definitions that do not always reflect hydrological processes. We introduce RVEIM, a parsimonious method for event identification that improves both robustness and physical plausibility. Applied across 467 Australian catchments, RVEIM reveals systematic shifts in event runoff coefficient distribution, demonstrating how event-scale rainfall-runoff relationships vary with climate regime.
