Short summary
Hydrologic models use daily precipitation and potential evapotranspiration for streamflow estimation. The effect of an increase in rainfall intensity on the long-term water balance is not adequately accounted for in these hydrologic models. This study, using data from a forested watershed in France, shows that the effect of peak rainfall intensity on runoff prediction is insignificant for two models tested, and model performance is unlikely to improve when peak daily precipitation is included.
