Abstract
Empirical orthogonal functions (EOF) have been used to characterize spatial variability of daily and monthly rainfall and runoff in Indiana. Data from a few of the surrounding states have also been used in the analysis. After a brief discussion of the theory underlying EOF analysis, results of data analysis are presented. These results indicate that the data can be efficiently compressed and that hydrologically and meteorologically homogeneous areas can be objectively delineated by using EOF analysis.
