Abstract
In this research the rainfall intensity data in mm/hr for the period ( 1982-1990 )
of nine years are collected for duration 3 to 13 hour from a station at Hamam - Al Alil
( Small town 25 km from Mosul ). Data generation for long period is generated from the
historical records by using uniform and normal distribution.
Physical and Statistical tests for comparing the historical and generated data will
indicate that Markov process of 1st degree is better than 2nd degree for two distribution.
