In 2019, Harvey is taking another look at possible overflow points for the
glacially-dammed Tsangpo River, and not remembering exactly what he did in the past.

The figures below show how ice might have affected overflow through the Subsansari River.
All analysis was naively done on the 3" DEM by raising the lake level until
it poured over in another direction.
