ANNOUNCEMENTS
Flash floods in the Himalayan region are frequently abrupt and highly destructive, driven by short-duration, high-intensity rainfall episodes. The interrelationship between climatic variables and geomorphological features in this area exacerbates the flood risk, necessitating precise prediction and effective management strategies. The Ravi River Basin, located in the northwestern Himalayas, is equally vulnerable and unchartedly studied for such risks in the Indian extents and is vulnerable due to its specific geographical attributes and the pronounced influence of the Indian monsoon. Historical rainfall datasets are comprehended to identify patterns and trends, providing a basis for forecasting future events. The catchment assessment involves an examination of the topographical and hydrological characteristics of the basin, pinpointing areas with high runoff potential and heightened flood susceptibility.
The study's findings further indicate substantial inundation risks across various sections of the basin, including regions traditionally perceived as less vulnerable due to their elevation. The effects of steep terrain and intense rainfall can result in rapid water accumulation and flash flooding, posing significant threats to both upstream and downstream communities.
