Abstract: Water scarcity is one of hill towns’ biggest issues. Several studies have disclosed the effects of variation in rainfall on worldwide water resources. In this research, we analyzed monthly, seasonal, and annual rainfall patterns in Dharamshala Kangra in comparing with Four neighboring districts of Himachal Pradesh, a Western Himalayan Indian state. The analytical processes include the evaluation of time series. Monthly rainfall information for five districts namely Kangra, Hamirpur, Mandi, Solan, and Una of Himachal Pradesh state from 1901 to 2017 was used to evaluate the region’s changing rainfall pattern. The information used in this research is predominantly 117 years of precipitation from the years 1901–2017, obtained from the Indian Meteorological website of the Indian Water Portal and the Meteorological Center of Shimla (H.P.). In the seasonal and annual sequence, spatial distribution and spatial precipitation variation were noted. Mann-Kendall test for trend assessment was used in the research. The results of the reduction in rainfall have been observed. For about five months, an apparent decrease in precipitation was observed, namely: March, July, September, November, and December. June and October months are also close to the trend of decreasing rainfall. Understanding rainfall patterns would be very useful in predicting the future course of water re-source management in hill towns and helping water resource managers to plan and introduce appropriate water management measures in hill towns. The article concludes with important suggestions on water resource management problems and difficulties in hill towns and sustainable solutions opportunities.
