river classification

River classification is a way to categorize rivers based on their size, flow, and features. Types include small streams (creeks or brooks), which are narrow and shallow; medium rivers, which are larger with steady flow; and large rivers, which are wide and carry significant water volumes, often forming basins or deltas. Classifications can also consider whether a river is perennial (flows year-round) or seasonal (flows only part of the year). This system helps in managing water resources, planning infrastructure, and understanding ecological dynamics.
