a view on the upstream side, with the water from the impounded
river flowing to the right and encroaching on the toe of the slide.

On the night of August 1-2, a large landslide occurred along the Sunkoshi River in northern Nepal, damming the river and creating an urgent crisis. I'm not going to follow this event because
Dave Petley's landslide blog will be providing excellent coverage. It is the peak of the monsoon season and so the impounded lake behind the landslide is likely growing fast and, Dave believes, may already be overtopping the dam. It also appears that the dam is in fine-grained materials and so the likelyhood of a breach is high. The valley downstream is heavily populated (evacuation has apparently already begun) and the main road from Nepal into China is blocked. The highway, however, does provide a route to bring in heavy machinery and crews to work on excavating a channel through the slide.
