Future hydrology and hydrological extremes under climate change in Asian river basins

Abstract The diverse impacts of anthropogenic climate change in the spatiotemporal distribution of global freshwater are generally addressed through global scale studies, which suffer from uncertainties arising from coarse spatial resolution. Multi-catchment, regional studies provide fine-grained de...

Multi-catchment, regional studies provide fine-grained details of these impacts but remain less explored.
