Abstract

The study explore trend of short crop ETusing 24 years dataand estimated using method suggested by Penman–Monteith method. The trends analysis was done by Mann–Kendall method and the Sen’s Slope estimator. The study found that the south Konkan region has decreasing trend for all stations except the Harnai station. The magnitude of the trend was high for Wakawali and Mulde stations. The present study is very advantageous for development of existing water assets, irrigation system design, and irrigation scheduling and water balance studies of the study area.
