The area of land where two rivers meet is called a confluence. A confluence occurs when two or more watercourses join together, forming a larger river or waterbody. This geographical feature is significant for various ecological, cultural, and historical reasons. Confluences often serve as fertile land due to the nutrient-rich sediments deposited by flowing water, enhancing biodiversity and supporting local ecosystems. Historically, many settlements have developed near confluences because of the resources and transportation routes they provide, making them vital in human civilization.
