Effective precipitation duration for runoff peaks based on catchment modelling

摘要

Graphical abstractDisplay OmittedHighlights?The effective precipitation duration is introduced as a new characteristic.?This quantity is used to characterize precipitation events and catchment response.?These effective precipitation durations were estimated for nine Swiss catchments.?For the highest peaks typical effective precipitation durations are about 12?h.AbstractDespite precipitation intensities may greatly vary during one flood event, detailed information about these intensities may not be required to accurately simulate floods with a hydrological model which rather reacts to cumulative precipitation s
