Abstract

This research is mainly based on rainfall variability in Zhob district of Balochistan. Balochistan is the largest province of Pakistan as far as area is concerned. A drought is the most frequently faced disaster in Zhob district. Zhob not only receives the winter rainfall from western depression but also receives some rainfall from the summer monsoon as well. For sustainable growth and better management of water resources, it is highly recommended to use resources wisely. Rainfall variability is one of the effects of climate change. That is why spatial and temporal analysis of rainfall is getting huge attention from scientists internationally. Rainfall data for district Zhob of 22 years (1999- 2020) was analyzed to find the annual trend of rainfall. The trend analysis was done through the Man-Kendal test & Sen’s slope estimator. The results indicate that there are positive and negative trends but are not statistically significant. High rainfall variability is also found.
