Conclusion
An alluvial plain is a flat landform created by the deposition of sediment carried by a river, stream or other water body. These plains are formed by the gradual accumulation of sediment over time and are found in many parts of the world. In this article, we will explore the definition, origin, meaning, associations, synonyms, antonyms, and example sentences related to alluvial plain.
Definitions
An alluvial plain is a flat or gently sloping landform created by the deposition of sediment carried by a river, stream, or other water body. These plains are formed by the gradual accumulation of sediment over time and can range in size from small areas to vast regions.
Origin
Alluvial plains are formed through the process of erosion and deposition. As water flows through a river or stream, it picks up sediment and carries it downstream. When the water slows down, the sediment is deposited on the riverbed or on the surrounding land. Over time, this process can create a flat or gently sloping plain.
Meaning in different dictionaries
According to the Oxford English Dictionary, an alluvial plain is “a level or gently sloping stretch of land that has been formed by the deposition of sediment carried by a river or stream.” Merriam-Webster defines it as “a level or gently sloping plain made of sediment deposited by a river.” The Cambridge Dictionary describes it as “a flat area of land that has been formed by the deposit of sediment carried by a river or other body of water.”
Associations

They are also important for water management, as they can act as natural floodplains and help to reduce the risk of flooding in nearby areas. Alluvial plains are also important for mining, as they can contain valuable minerals and resources.
