Above: modelled (y axis) vs observed (x axis) BOD fluxes (in logarithmic scale), from left to right: mean annual load (t/y); specific loads (t/km2/y); and concentrations (mg O2/L). Calibration dataset is indicated with black circles and validation dataset in grey crosses. Below: boxplots of modelled flux residuals (normal scale) for calibration and validation datasets.
