Most rivers of Kerala flow in which general direction?
Last Updated:
This question examines an important river-or-lake fact: “Which river system drains Kerala?” The correct answer is West-flowing rivers. Kerala is drained predominantly by west-flowing rivers that originate from the Western Ghats and flow into the Arabian Sea. These include Periyar, Bharathapuzha, Pamba, Chaliyar, Chalakudy, and many others. These rivers are short, fast-flowing, and rain-fed. Rivers and lakes are central components of the hydrological cycle and physical geography. A river system includes its source, tributaries, distributaries, drainage basin, watershed, channel, floodplain, delta or estuary and final outlet. River behaviour depends on relief, geology, rainfall, snowmelt, sediment load, vegetation and human intervention.
