This study explores the diurnal relationship between total precipitation and volumetric soil water content in Agartala, India, a plateau surrounded by low altitude hills over the period from June 8 to June 22, 2023 following a heavy rainfall event. Hourly data is collected from the Copernicus ERA5 dataset and analyzed to investigate spatial–temporal correlations between precipitation and soil moisture at key spatial points, including the central location (Agartala) and the eastern and western borders of the study area. Dual-axis time series plots illustrate synchronized fluctuations between precipitation events and soil water content across these points. This research contributes to a deeper understanding of the hydrological cycle and water retention dynamics at heavy rainfall event time offering valuable insights for water resource management in Agartala.
