Pucknell S, Kjeldsen TR, Haxton T, Jeans J and Young AR (2020) Estimating the probable maximum flood in UK catchments using the ReFH model. Dams and Reservoirs 30(3): 85–90, https://doi.org/10.1680/jdare.20.00015.

The authors have identified that the estimated summer model parameters and subsequent final summer results reported were incorrect. Accordingly, the relevant figures and tables have been updated (see below). These changes do not have an appreciable impact on the final results hence no changes to the text or conclusions of the study are necessary.

(corrected). Comparison of PMF as estimated by the ReFH2 model (y-axis) and the FSR/FEH method (x-axis) for both summer (triangle) and winter (circle) events. ReFH2.3 results are presented for comparison.
