Fig. 2: Cost of identical parameter combinations applied to bedload (BL) and suspended load (SSL) for 2020 and 2021.
From: Different geomorphic processes control suspended sediment and bedload export from glaciers
Cost is defined as relative error or \(\xi (\theta)=\frac{1}{{n}_{r}}\sum \left\vert \right.\frac{\overline{Q}(\theta)-\overline{{Q}_{o}}}{\overline{{Q}_{o}}}\left\vert \right.\), where nr is the number of runs, θ is a parameter set, \(\overline{Q}(\theta)\) is model output and \(\overline{{Q}_{o}}\) is observations. Note that no parameter combinations result in model outputs that perform well for both BL and SSL.
