Abstract :
This paper studies the probability analysis and estimation of Annual Maximum Monthly Rainfall (AMMR) for different return periods which is very useful for crop planning. We fit various distributions namely NORMAL, LOG NORMAL, LOG PEARSON and GUMBEL for the rainfall data of Dharmavaram Rain Gauge Station (RGS) in Anantapuramu district. Using goodness of fit we determine the best fit probability distribution for predicting the AMMR for different return periods. Based on the obtained numerical results, conclusions are drawn.

Key-Words / Index Term :
AMMR, Rainfall, Probability distribustions, Goodness of fit, RGS
