This paper examines the hydrometeorological factors contributing to the devastating floods in Himachal Pradesh, India, during July 2023. The study analyzes meteorological and hydrological data from various observation stations, along with reanalysis data from ERA5, SMAP-L4, and FLDAS-NOAH, to understand the causes of the flood peak. The analysis reveals that the combination of extremely heavy rainfall, near-saturation antecedent moisture content, and snowmelt was the primary factors leading to the inflation and sustenance of the flood peak. The Himalayas, acting as a natural barrier and water tower for Asia, play a crucial role in regulating the climate and supplying water to major rivers. However, climate change has increased the frequency and intensity of extreme precipitation events, exacerbating the impact of floods in the region. The paper highlights the need for a comprehensive understanding of multiple causative factors to develop resilient solutions for managing such events and reducing damage.This paper examines the hydrometeorological factors contributing to the devastating floods in Himachal Pradesh, India, during July 2023.
