No. 2 Brahmaputra River
The Brahmaputra River, located in Bahaduradbad, Bangladesh, runs through the Himalayas, the Assam Valley, and Bangladesh, with a length of approximately 1,800 miles. The river is navigable, and is used for transportation and irrigation. Yet, its flooding has caused serious damages to nearby towns, especially when the snow of the Himalayas melts down in the spring, increasing its water volume. Moreover, the Brahmaputra River has something called a tidal bare; this is when incoming tides form waves that travel up the river against the direction of the current, which creates tidal waves, and makes the river very hard to navigate.
