Rainfall Data Analysis and its Environmental Impact on Ground Water Recharge of Thandla, District Jhabua, Madhya Pradesh.
Rainfall records of Thandla area for a period of 25 years (1987 to 2011) have been collected and analyzed by adopting both mathematical and statistical methods. Rainfall data of Thandla area indicate a variation range from 423.0 to 1655.6 mm. The minimum annual rainfall (423.0 mm) has been recorded during 2000, whereas the maximum rainfall (1655.6 mm.) has been noted during. 1994, and the computed annual average rainfall value is 905.116 mm. The statistical analysis of rainfall data of the Thandla indicate values of means 904 mm., median 1425 mm., standard deviation 334.66 mm., mode 1900 mm., co-efficient of variation 37.01 mm., co-efficient of skewness - 2.976. The determined values of statistical parameters reveal a negative trend of rainfall. The environmental impacts of rainfall trends in ground water recharge have been discussed.
