Riverbank collapses are hugely under-researched, and indeed the amount of data and imagery available on collapse events is poor. A few days ago Ron Dorn highlighted these two amazing riverbank collapse videos from the Missouri River to the south of Bismarck in North Dakota, USA. The first takes 30 seconds or so to get going, but do hang on in there. It is worth it:

These are quite small failure events, but are really quite interesting.
