Application of multi-variate analysis in hydrology, An

Abstract

Multivariate analysis was used to make a selection of some of the more meaningful physical parameters dealing with the response of a small watershed to flood producing rainfall. Factor Analysis, Principal Component Analysis and a Correlation Coefficient Matrix was utilized. The list of 24 parameters was reduced to a list of 8 parameters. This reduction results in a very material economy in the encoding of relevant geomorphological data in flood analysis.
