Abstract:
The present study has been undertaken to determine the expected amount of rainfall in Khordha district at different probability levels (90%, 75% and 50%) using Incomplete Gamma Probability distribution in Weather Cock model. Rainfall data of 25 years (1993-2017) of Khordha district has been collected from Special Relief Commissioner (SRC), Govt. of Odisha to estimate annual, seasonal and monthly rainfall probabilities. The analysis of 25 years rainfall data revealed that the annual average rainfall of Khordha district is 1433 mm which is received in 94 rainy days. The average annual predicted rainfall at 90%, 75% and 50% probability levels are 1092.6 mm, 1238.7 mm and 1415.9 mm respectively. 31 SMW has the record of receiving highest amount of rainfall at all the three probability levels. From the onset of monsoon 23-25 SMW district receives a good amount of rainfall and it goes on increasing up to 40 SMW. At 75% of assured probability level monsoon period may receive 516 mm of rainfall and post monsoon period may receive 37.6 mm of rainfall. So, the best suitable crops in medium and lowlands are rice during kharif season and pulses like black gram, green gram, soybean, horse gram, rice bean and oil seeds like sesame, mustard can be taken up during rabi season.
