==Geography==
The [[Kaveri]] river splits into two at a point {{Convert|20|mi|km}} west of Kallanai. The two rivers form the [[Srirangam Island|island of Srirangam]] before joining at Kallanai. The northern channel is called the [[Kollidam River|Kollidam]] (Coleroon); the other retains the name Kaveri, and empties into the [[Bay of Bengal]] at [[Poompuhar]]. On the seaward face of its delta are the seaports of [[Nagapattinam]] and [[Karaikal]].<ref>{{cite web |url=http://arno.unimaas.nl/show.cgi?fid=14861 |title=Dikes and Dams, Thick with Politics |author=Wiebe E.

==Description==
The purpose of the Kallanai was to divert the waters of the Kaveri across the fertile [[River delta|delta]] region for irrigation via canals and to its northern delta branch Kollidam/Coleroon. Downstream of the barrage, the river Kaveri splits into four streams known as Kollidam Aru, Kaveri, Vennaru and Puthu Aru. However, the flood waters can be allowed, by opening the barrage/anaicut gates, to pass through the other three delta branches also to join the sea.<ref>{{cite web |url=http://india-wris.nrsc.gov.in/wrpinfo/index.php?title=Grand_Anicut_A00677 |title=Grand Anicut A00677 |publisher=WRIS, India|access-date=7 November 2016}}</ref> It is constructed from unhewn stone spanning the Kaveri and is {{convert|329|m|abbr=on}} long, {{convert|20|m|abbr=on}} wide and {{convert|5.4|m|abbr=on}} high.<ref>{{cite web |url=http://www.iimtrichy.ac.in/home/students/places_to_visit |title=Places to visit |publisher=IIM-Trichy, India |access-date=7 November 2011 |archive-url=https://web.archive.org/web/20111219124955/http://www.iimtrichy.ac.in/home/students/places_to_visit/ |archive-date=19 December 2011 |url-status=dead }}</ref> The dam is still in excellent condition, and supplied a model to later engineers, including Sir [[Arthur Cotton]]'s 19th-century dam across the Kollidam, the major distributary of the Kaveri.<ref>{{cite web|url=http://lawlibrary.unm.edu/nrj/48/3/03_agoramoorthy_indian.pdf |title=The Check-Dam Route to Mitigate India's Water Shortages |author1=Govindasamy Agoramoorthy |author2=Sunitha chaudhary |author3=Minna J.

The delta farmers of Tamil Nadu have demanded the Tamil Nadu government to honor [[Karikala Chola]]n, who built this dam.
