The Drainage Basin Hydrological Cycle

The drainage basin is the catchment area from which a river system obtains its water. An imaginary line called the watershed delimits one drainage basin from another.The watershed generally follows a ridge of high land; any rain falling on the other side of the ridge will eventually flow into another river in the adjacent drainage basin.

The drainage basin hydrological cycle contains a number of inputs, outputs, stores and transfers.
