-
A.
drainage basin
chosen
A drainage basin is a land area where all precipitation collects and drains off into a common outlet, such as a river, lake, or ocean.
-
B.
river basin
A river basin is the land area drained by a river and all its tributaries, bounded by topographic divides that separate it from adjacent basins.
-
C.
waterway network
A waterway network is an interconnected system of natural and artificial water channels (such as rivers, canals, and streams) designed or utilized for the movement, distribution, and management of water and waterborne transport.
-
D.
hydrologic region
A hydrologic region is a geographically defined area characterized by similar water cycle processes, drainage patterns, and hydrologic conditions that influence how water moves, accumulates, and is stored in the landscape.
-
E.
watershed divide
A watershed divide is a geographical boundary, often a ridge or highland, that separates adjacent drainage basins so that precipitation on each side flows into different river systems.
- F. None of above.
