In this system, the "accuracy" estimation refers to assess the precision of preferred prediction using the indicators like Nash-Sutcliffe efficiency, relative errors and so on. While the "reliability" assessment means to evaluate the reasonability of predicted interval using the indicators like containing ratio, deviation index and so on. Meanwhile, a new "reliability" assessment indicator named the containing ratio coefficient is proposed to assess the comprehensive reasonability of multiple predicted intervals. The accuracy-reliability joint assessment criteria system is tested in Wangjiaba subbasin in Huaihe River. The results suggested that this system gives a synthetic evaluation of the probabilistic flood forecasting. %R 10.18307/2020.0222 %U http://www.jlakes.org/ch/reader/view_abstract.aspx %1 JIS Version 3.0.0
