The coefficient of correlation values of those two models (FFBP and CFBP) is
represented in Figs. 12 and 13.
In almost both cases, the correlation coefficient (R) value ranges between 0.96
to 0.99, which indicates a good correlation among precipitation and runoff data
sets. FFBP and CFBP model have been run for two types of data sets. (15 + 1)
Years monsoonal data sets for the whole catchment and (12 + 4) years monthly
total rainfall-runoff values for the whole catchment have been utilized. Here, 15 and
12 years of data have been used for training and validation purposes, and the rest one
and four years of data were used for simulation purpose. For (12 + 4) years dataset,
R values are 0.993 and 0.996, respectively, in the CFBP and FFBP model, which are
