Climate change is heating up the world, affecting water resources like rivers. Scientists in Nepal studied how different climate models predict changes in the Thuli Bheri River Basin. They used a computer model to estimate future river flow, focusing on the years 2021-2099. The results show that temperatures will rise, impacting water availability. Rainfall might decrease or increase slightly, with an overall increase in river flow of 9-13%. However, these predictions have wide variations and show more uncertainty during heavy rain seasons. This research helps prepare for water management challenges in the future.
