Bellary region is characterized as one of the semi-arid zones of Karnataka, having only 508 mm of annual rainfall distributed over 35 rainy days. The ill-distribution of rainfall creates at least 5 drought years in every decade. The average rainfa1l distribution shows that there is a total failure in Kharif season. However, some assured rainfall received during September and October a better prospect which assumes for rabi season .This problem can be overcome to. certain extent by scientific management of crops and water. This calls for detailed analysis of any Important water resources Issues. Keeping this mind, an attempt made in this paper to analysis short and long period rainfall data. The probabilities analysis of. rainfall for shorter periods for identification of suitable periods for sowing, return period analysis for designing of soil and water conservation structures and determining the size of storage structures, the identification of number of Various rainfall events for designing water harvesting system for crop and water management are carried out and presented in this paper.
