Morphometric characteristics of Nandiyar river basin, Tamil Nadu, India

Abstract

Nandiyar river basin, located in the central Tamil Nadu plains, was subjected to dimensional analysis. Initially, through correlation matrix, the interrelationship between the various morphometric variables of the basin was found out. Using factor analysis, the individual morphometric parameters were grouped into a small number of factors and through the analysis of the factor scores, the sub basins of the Nandiyar river were studied to find out the existing relation between the factors and the sub basins. In addition, remedial measures have been suggested for the various environmental problems of the Nandiyar basin.
