Word Origin and History for interbasin
"large shallow vessel or dish," c.1200, from Old French bacin (11c., Modern French bassin), from Vulgar Latin *baccinum, from *bacca "water vessel," perhaps originally Gaulish. Meaning "large-scale artificial water-holding landscape feature" is from 1712. Geological sense of "tract of country drained by one river or draining into one sea" is from 1830.
- A region drained by a river and its tributaries.
- A low-lying area on the Earth's surface in which thick layers of sediment have accumulated. Some basins are bowl-shaped while others are elongate. Basins form through tectonic processes, especially in fault-bordered intermontane areas or in areas where the Earth's crust has warped downwards. They are often a source of valuable oil.
- An artificially enclosed area of a river or harbor designed so that the water level remains unaffected by tidal changes.
