On esitetty uusi teoria siitä, kuinka putoukset syntyvät:
- Sen mukaan veden pyörteet voivat itsessään käynnistää putouksen synnyttävän prosessin. Siihen ei välttämättä tarvita jotain ulkopuolista tekijää kuten maanjäristystä, mikä muokkaa pinnanmuotoja joen kohdalla tai sitä, että kallioperässä on eri tavalla kulutusta kestäviä kohtia.

Visualisointeja:

Lots of things going on here, can anyone name one of the natural processes at work? #geography #geographyteacher #geomorphology pic.twitter.com/E2YyvIxK9i

Great little movie that’s great for students to visualise how lateral #erosion and #deposition alters the course of a river with #meander and #oxbowlake #georaphy #geographyteacher pic.twitter.com/XBvVi6VlM2

The Padma is one of the major rivers of Bangladesh, and satellite imagery shows that it has been growing in size, transforming in shape, and changing in location for at least the past 30 years.
