The Avon River is a river in Western Australia. A tributary of the Swan River, the Avon flows 240 kilometres (150 mi) from source to mouth, with a catchment area of 125,000 square kilometres (48,000 sq mi).
A drainage basin is an area of land where all flowing surface water converges to a single point, such as a river mouth, or flows into another body of water, such as a lake or ocean. A basin is separated from adjacent basins by a perimeter, the drainage divide, made up of a succession of elevated features, such as ridges and hills. A basin may consist of smaller basins that merge at river confluences, forming a hierarchical pattern.
