Abstract

The planning, development, and management of water resources are significantly influenced by meteorological processes, which are significantly impacted by climate change. Trends become apparent as a result of these effects. Using nonparametric Mann-Kendall (MK), modified Mann-Kendall (MMK), and Theil-Sen slope estimator tests based on 60 years of data. The current study was conducted to evaluate the historical patterns of annual rainfall and rainy days in the Jodhpur zone of Rajasthan, India (1957-2016). Out of 27 stations, the annual rainfall at seven stations had a significant increasing trend. In the case of annual rainy days, only two stations showed a significant increasing trend. The dramatically increasing trend in rainfall at seven stations in the Jodhpur zone has shown that arid state of Rajasthan has been affected by climate change. The findings of this study could be used as preliminary data for planning and management of agricultural and water resources, as well as for designing soil and water conservation structures to increase the region's water availability.
