It is suggested that factor analysis, if used in the classical manner, will never be of great value for hydrologic analysis. However, factor analysis used as a numerical procedure for screening variables and building effective regression equations is a useful and powerful tool for hydrologie analysis that can be expected to yield equations that outperform others when used as predictors for control samples.
