The statistical analysis of hydrologic data derives importance in the planning and design of water resource projects which require information on different hydrologic events that are governed by probability distribution. The present study attempts to select an appropriate probability distribution function to forecast maximum hourly rainfall intensity during southwest monsoon at Kurnool and Ananthapur raingauge stations located in the drought prone area of Rayalseema region of Andhra Pradesh.

Development and effective utilization of groundwater resources is essential in arid and semi-arid regions for activities such as water supply and irrigation. The present study aims to analyze, statistically, the groundwater data at the piezometric stations of upper Swarnamukhi basin in the drought prone Rayalseema region of Andhra Pradesh and to develop relationships through multiple linear correlation and regression analysis.
