 ABSTRACT

The weekly rainfall data from 1967 to 2016 for 5 stations of Pratapgarh district was used to analyse rainfall trend. Spatial distribution and temporal variation of rainfall were observed in weekly and annual rainfall data series. Mann Kendall test and Sen’s slope estimator were used for the trend analysis. IDW interpolation technique was used for analysing spatial variability of rainfall of the district. The statistical indices such as mean, standard deviation, skewness and kurtosis of rainfall were calculated. The results showed that, peak average weekly rainfall (89.50 mm) of the district was observed in meteorological week MW-31, whereas the minimum rainfall (3.36 mm) was seen in MW-42. Mann Kendall test and Sen’s slope estimator confirmed that, the annual rainfall data series of all the stations in the district has no trend. The trend was detected in weekly rainfall data series of MW-30 only. The hypothesis of no trend was accepted for all other weekly rainfall data series.

Key words: Rainfall trend, Mann-Kendall test, IDW interpolation etc.
