Editing Waterfall (section)

== Definition and terminology ==
A waterfall is generally defined as a point in a river where water flows over a steep drop that is close to or directly vertical. In 2000 Mabin specified that "The horizontal distance between the positions of the lip and [[plunge pool]] should be no more than c 25% of the waterfall height." There are various types and methods to classify waterfalls.{{Sfn|Goudie|2020|p=61}} Some scholars have included [[rapids]] as a subsection.<ref name=":1">{{Cite journal|last=Hudson|first=Brian J.|date=2013|title=The Naming of Waterfalls|url=https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1745-5871.2012.00780.x|journal=Geographical Research|language=en|volume=51|issue=1|pages=85–93|doi=10.1111/j.1745-5871.2012.00780.x|bibcode=2013GeoRs..51...85H |issn=1745-5871|access-date=26 August 2021|archive-date=26 August 2021|archive-url=https://web.archive.org/web/20210826130300/https://onlinelibrary.wiley.com/doi/abs/10.1111/j.1745-5871.2012.00780.x|url-status=live}}</ref> What actually constitutes a waterfall continues to be debated.{{Sfn|Hudson|2013b|p=372}}

Waterfalls are sometimes interchangeably referred to as "cascades" and "cataracts", though some sources specify a cataract as being a larger and more powerful waterfall{{Sfn|Goudie|2020|p=61}}<ref>{{Cite web|title=Cascade/Cataract/Waterfall – History of Early American Landscape Design|url=https://heald.nga.gov/mediawiki/index.php/Cascade/Cataract/Waterfall|access-date=2021-08-28|website=heald.nga.gov|archive-date=28 August 2021|archive-url=https://web.archive.org/web/20210828160934/https://heald.nga.gov/mediawiki/index.php/Cascade/Cataract/Waterfall|url-status=live}}</ref><ref>{{Cite web|title=Definition of Cataract|url=https://www.merriam-webster.com/dictionary/cataract|url-status=live|access-date=2021-08-28|website=Merriam Webster|language=en|archive-date=28 August 2021|archive-url=https://web.archive.org/web/20210828160926/https://www.merriam-webster.com/dictionary/cataract}}</ref> and a cascade as being smaller.<ref>{{Cite web|title=Definition of Cascade|url=https://www.merriam-webster.com/dictionary/cascade|url-status=live|access-date=2021-08-28|website=Merriam Webster|language=en|archive-date=28 August 2021|archive-url=https://web.archive.org/web/20210828160925/https://www.merriam-webster.com/dictionary/cascade}}</ref> A plunge pool is a type of [[stream pool]] formed at the bottom of a waterfall.<ref>Robert L Bates, Julia A Jackson, ed.
