Analysing Rainfall Patterns using Frequency Distribution and Probability Plotting in Kunigal Taluk, Tumkur District, Karnataka

Land, water, and soil are limited natural resources that are all the same but are distributed unevenly; their widespread use and conservation as the world's population grows is a major source of concern; to close the demand-supply gap between resources and ever-increasing demand, it is critical to conserve natural resources with proper prioritization for long-term development. The current study primarily focused on rainfall frequency distribution and determining the frequency of likely occurrence of Hydrologic events, as well as frequency distribution plotting and probability plotting for Kunigal Taluk. The research region has eight rain gauge stations, with monthly rainfall data for the premonsoon, southwest monsoon, and northeast monsoon recorded and studied from 1901 to 2013. By using standard approaches, the rainfall data is examined using actual rainfall vs. projected rainfall, time series of hydrological and meteorological events, and their normal components. The magnitude of such events projected to be expected for a specified probability and return 113 years is 1259.9 mm, and the event is 990.2 mm in 6.30 years. For 113 years, the first-degree equation is Y = 748.45+0.9302x. We are mostly covering rainfall data and its frequency in this article, By evaluating the maximum and the range of the cumulative deviations from the mean, the homogeneity of the data of a time series is tested.
