This process, known as river piracy, set in motion a chain of geological events that reshaped the landscape, scientists reported Monday in the journal Nature Geoscience.
While some instances of river capture and landscape remodeling began millions of years ago, others are happening today, she added.
Evidence of one ancient example still exists around the edges of the Himalayas, where long-ago river capture eroded deep gorges.
Han’s simulations suggested that river capture would have dramatically increased the flow of water in the Kosi’s lower segments.
Compared with river piracy, erosion and uplift unspool over a much longer time span — and are still happening with Everest, Lhotse and Makalu.
