This model is a model of the total water requirement determined by the influencing factors of this year. 29 influencing
factors are shown in Table 1 and training set consists of data of this influencing factors from the year of 1997
to 2011. The influencing factors of this year determine the total water requirement of the same year. We built the best
model of the total water requirement via SVR using best parameters. Table 2 shows the results of the regression of
the total water requirement measured by billion cubic meters from the year of 1997 to 2011.
