Pena-Arancibia, Jorge; Zhang , Yongqiang; Pagendam, D E; Viney, Neil; Lerat, Julien; Van Dijk, Albert; Vaze, Jai; Frost, Andrew

Description

Common streamflow gauging procedures require assumptions about the stage-discharge relationship (the 'rating curve') that can introduce considerable uncertainties in streamflow records. These rating uncertainties are not usually considered fully in hydrological model calibration and evaluation yet can have potentially important impacts. We analysed streamflow gauge data and conducted two modelling experiments to assess rating uncertainty in operational rating curves, its impacts on modelling...[Show more]
