Climatic Variability Analysis of a Garhwal Himalayan Watershed, Uttarakhand

Manju Arya, Deepak

Abstract: Climate change is the most serious threat confronting the globe today, and it is predicted to have its impacts on different sectors. A study of climate changeability, trend and estimate for better water resource management and planning in a watershed is very significance. The present study focuses on the study trend analysis of the temperature and precipitation of a central Himalayan watershed viz., the Mathugad in district Chamoli of Uttarakhand state. For this purpose, IMD Gridded daily data over the time period of 40 years (1981?2020) have been used. Statistical trend analysis techniques, namely the Mann?Kendall test and Sen?s Slope estimation have been done to examine trends. The results indicate that the average annual temperature shows a significant increase which has found significant at 95% confidence level no marked change were notice in the average annual rainfall but the rhythm of the rainfall has changed significantly. Due to temperature rise and change in rainfall rhythm the hydrological system and agriculture is being adversely affected in the region. The present study also attempts to define the impact of temperature rise and change in rainfall rhythm in springs, streams and river.
