Abstract : This study focused on the statistical and trend analysis of rainfall of over eleven years from 2010 to 2021 of Kanthatmakurvagu catchment area of Warangal urban and rural districts of Telangana state. The data was collected from the six rain gauge stations falling in the catchment area. The study involved analysis of annual and seasonal statistical analysis such as mean, median, standard deviation, coefficient of variation, skewness and kurtosis. Trend analysis of same seasons are also analysed and reported. The results indicated that annual mean rainfall was found to be 1153.3 mm. About 82% of the rainfall was contributed in southwest monsoon period. Maximum rainfall in the southwest monsoon was 1590.5 and minimum was 549.8 mm. Annual maximum rainfall was found to be 1870.6 mm and minimum was 717.5 mm. Annual and all seasonal standard deviation considerably large, this indicates there is larger variation in rainfall pattern. The coefficient of variation indicates the erratic nature of rainfall. Positive skewness indicating the region is asymmetric and it lies to the right of mean that is right skewed. Annual kurtosis value indicating slightly leptokurtic in nature. The northeast and winter and summer seasons showed a negative kurtosis which indicated a flat distributions during this seasons and in southwest seasons it showed a positive kurtosis which indicated a peaked distribution. Highest standard deviation considerably high in July and August indicates there is larger variation, while remaining months has low indicates smaller variation in rainfall pattern. The coefficient of variation ranges between 0.1 and 0.9, which indicates February, was more varied than other months. Positive months showed a positively skewed distribution in the area. The months showed a negative kurtosis indicated a flat distributions and positive kurtosis which indicated a peaked distribution.
