Short summary
Rating curves are used to estimate flow from recorded stage at hydrometric stations. Uncertainties in these flows are generally not estimated or reported. This paper proposed an approach to develop rating curves and to assess the corresponding uncertainties in estimated flow that can be readily applied to large-scale hydrometric networks. The mean standard deviations of estimated flows are of the order of 6.5 %. Uncertainties increase significantly for low stages and can reach values larger than 20 %.
