| Abstract: | Using the alternative renewable process and run theory, this study investigates the distribution of drought interval time,
mean drought interarrival time, joint probability density function and transition probabilities of drought events in the Kansabati
River basin in India. The standardized precipitation index series is employed in the investigation. The time interval of SPI
is found to have a significant effect of the probabilistic characteristics of drought. |
