ABSTRACT Floods are amplified and attenuated by features processes across spatial scales, defined here as flood dynamics. We review synthesise these influences at the catchment, river network reach scales a means of integrating understanding controls on dynamics identifying key questions that arise because differences in techniques investigation disciplinary emphases between scales.
