“…They found that the input data role is more significant than the role of the hydrological parameter in peak flow estimation. Others have investigated the uncertainty caused by input and hydrological parameters (e.g., Bae et al, 2018;Zhang et al, 2016), hydrological parameters and model structure (e.g., Butts et al, 2004;Jin et al, 2010), climate change, and hydrological parameters (e.g., Her et al, 2019;Meresa, 2019), climate change and flood frequency (e.g., Qi et al, 2016), frequency distribution parameters and types (e.g., Sun et al, 2017). These studies have shown that only one aspect of systematic and/or inherent uncertainty is insufficient to address the problem in estimating extreme flow.…”
