Study Notes
Drainage Basin Characteristics
- 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.
- A basin is separated from adjacent basins by a perimeter, known as the drainage divide, made up of elevated features like ridges and hills.
Terminology
- Other terms for a drainage basin include catchment area, catchment basin, drainage area, river basin, water basin, and impluvium.
- In North America, a drainage basin is commonly referred to as a watershed.
Boundary Determination
- A drainage basin's boundaries are determined by watershed delineation, a crucial task in environmental engineering and science.
Types of Drainage Basins
- A closed drainage basin, or endorheic basin, is where water converges toward the interior of the basin rather than flowing to the ocean.
