Models performance. Quantile-quantile plots of model behavior. Top 3 panels: Calibration period; middle 3 panels: Shorecast. Model prediction vs measured shoreline position for (a) and (d) HM; (b) and (e) ML; (c) and (f) model prediction vs measured shoreline rotation. Dashed grey line represent the average shoreline position during the calibration and the Shorecast period, respectively. R², RMSE, skill and λ for shoreline prediction for; (g–j) averaged shoreline position; (k–n) shoreline rotation. See supporting material for more information about the metrics and individual models.
