“…Uncertainty analysis allows the identification of uncertain parameters (Tung & Yen, 2005), a quantitative assessment of model reliability (Merz & Thieken, 2005;Montanari & Koutsoyiannis, 2012;Tung & Yen, 2005), and it provides a means of analyzing the robustness of flood risk management decisions. Furthermore, an analysis of the contribution of individual sources indicates where potential improvements in the method could have the greatest impact (Cullen & Frey, 1999;Hall & Solomatine, 2008;Sikorska et al, 2012) and therefore how uncertainty could be reduced (Qi et al, 2016), which is especially important for ungauged catchments (Sikorska et al, 2012). Although, uncertainty cannot be eliminated, its assessment at least enables its management (Koutsoyiannis, 2014).…”
