MEGHNA , a See also:river of See also:India. It forms, in the See also:lower See also:part of its course, the See also:great See also:estuary of the See also:Bengal See also:delta, which conveys to the See also:sea the See also:main See also:body of the See also:waters of the See also:Ganges and the See also:Brahmaputra, which unite at Goalanda in See also:Faridpur See also:district. The See also:united waters, turbid and of great See also:depth, are sometimes split into See also:half a dozen channels by See also:sand-See also:banks, sometimes spread into a wide See also:sheet of See also:water. The river enters the sea by four See also:principal mouths, enclosing the three large islands of Dakshin Shahbazpur, Hatia and Sandwip. It is navigable by native boats and river steamers all the See also:year; but the See also:navigation is difficult and some-times dangerous on See also:account of shifting sand-banks and snags, and boisterous See also:weather when the See also:monsoon is blowing. The most favourable See also:season is between See also:November and See also:February. AlIuvion and diluvion are constantly taking See also:place, especially along the seaboard, and in See also:Noakhali district the See also:land is said to have made rapid advance on the sea; while the islands fringing the mouth are annually being cut away and redeposited in fresh shapes. The See also:regular rise of the See also:tide is from To to 18 ft., and at springs the sea rushes up in a dangerous See also:bore. It is greatest at the See also:time of the biennial equinoxes, when navigation is sometimes impeded for days together. The tidal See also:wave advances like a See also:wall topped with foam of the height of nearly 20 ft., and at the See also:rate of 15 M. an See also:hour; in a few minutes it is past, and the river has changed from ebb to See also:flood tide. A still greater danger is the " See also:storm wave " which occasionally sweeps up the Meghna under a cydone.
