Abstract

Climate change has caused significant variations in precipitation across the different geographical regions of the world. A better understanding of rainfall trends, distribution, and features is essential for effective water resource management, particularly in areas with high spatiotemporal variability. This study examines the spatiotemporal changes in rainfall patterns of the Tunga River Basin which is located in the Western Ghats region of Karnataka, India. Also, the potential reasons for the rainfall variability in the region were investigated. The Tropical Rainfall Measuring Mission (TRMM) 3B43 monthly precipitation data for 24 years from 1998 to 2021 were used. The study revealed that the high-elevated areas are getting more rainfall compared to the lowlands, which shows the influence of topography on precipitation.
