Abstract
The annual extremes of rainfall for a region would be useful in planning of the irrigation pattern, reservoir operation, etc. For the coastal belt of Maharashtra, the rainfall is very intense and this is different from the inland districts. The present study aims to estimate the extremes of precipitation for the coastal districts of Maharashtra, namely Sindhudurg, Ratnagiri, Raigad, Mumbai City, Mumbai Suburban, and Thane. The data used for analysis is annual precipitation totals from the year 1901-2000, obtained from Indian Meteorological Department. To get the extremes of precipitation, peak-over-threshold sampling technique would be employed. Magnitude for 50 and 100 year extreme rainfall would be estimated by fitting suitable extreme value distribution from the Gumbel, the Weibul, Generalized Extreme Value and Generalized Pareto distributions.
