The morphological and climatic factors affecting runoff were studied using correlation and regression methods during 1989-'90. Two river basins of Kerala viz. west flowing Chaliyar and east flowing Kabbani were selected for the analysis. They were divided into sub-basins, each containing a river gauge station. Drainage area length and order of the main stream, maximum straight length of the sub-basin and rainfall were the chief factors influencing streamflow. Non-monsoon discharge was only a small fraction of the total discharge. Major portion of the monthly streamflow was from monsoon rainfall of the same month.
