This analysis quantifies runoff coefficient variations in transboundary river basins, indicating trends essential for water management.

Key Points

This research aims to quantify variations in the runoff coefficient across key transboundary river basins over two decades, using a water budget approach.
Analyzed runoff data from Ganga, Indus, and Brahmaputra basins from 2003 to 2021
Employed an ensemble mean approach to combine multi-source datasets including precipitation and evaporation
Evaluated contributions of evapotranspiration and storage coefficients to runoff coefficient variability
Brahmaputra Basin shows the highest average annual runoff coefficient at 0.71
Ganga and Indus Basins have average annual runoff coefficients of 0.41 and 0.40, respectively
Brahmaputra and Ganga Basins exhibit increasing runoff coefficient trends, while Indus shows a slight decline
