Abstract

Abstract The water availability days and calendar of the Pennar river basin has been worked out for 55 stations taking mean monthly potential evapotranspiration and mean monthly Actual Evapotranspiration (AE). From the analysis it is found that there are four periods in a calendar year, they are humid period, wet period, moderately dry period and dry period. The humid period is noticed in the months of September and October. The wet period is found in October, November and December. The moderately dry period is found in January, February, July and August months. And dry period is found in March, April, May and June months. Based on the water availability days and calendar crop management of the Pennar river basin is suggested region wise.
