The rainfall trend investigation study supports to judge the periodic pattern of rainfall. The quantifiable evaluation of the overall impacts of different elements, for example, changes in precipitation, temperature, evapotranspiration, environmental changes encouraged by a hazardous atmospheric deviation and human activities on the streamflow is critical for territorial appraisal of water assets and its feasible management. This study focusses on to analyze the seasonal rainfall trend in Hemavati Catchment, Karnataka, India. For the present study, thirty-two years (1990-2021) of seasonal rainfall trend has been examined using the Mann-Kendall assessment and Sen’s gradient estimation methods.
