Kosi River

The Kosi River, often called the "Sorrow of Bihar," is a major flood-prone river in northern India and Nepal. It originates in the Himalayan hills, flowing southeast through Bihar before merging with the Ganges. The river’s course is highly dynamic due to sediment deposition, leading to frequent shifts in its path. This causes annual flooding, damaging homes, agriculture, and infrastructure. Efforts like embankments and dams have been made to control floods, but challenges remain due to natural variability and sediment build-up. The river plays a vital role in local agriculture but demands ongoing management to reduce its destructive impact.
