The river flowsthrough three countries born in tibet ,flowing through India and then on toBangladesh. It has many names- Tsangpo inTibet, Lohit or Brahmaputra in India andJamuna in Bangladesh. 3. SOURCE AND TRIBUTARIES The Brahmaputra River hasits source in southwestTibet. The tributaries of theBrahmaputra River are someof the major rivers ofNortheast India. They feedmost of the fertile plains inthe zone. Several towns andcities have grown along thetributaries of BrahmaputraRivers. Some of the majortributaries of RiverBrahmaputra are as follows: 4. 3 PLACES IT FLOWS THROUGHTibetBangladeshAssam 5. CROPS GROWNThe main crops grown in theBrahmaputra Valley are : 6. PADDY JUTE 7.

The averagedepth of the river is 124 feet(38 m) and maximum depth is380 feet (120 m). 10. It is a classic exampleof a braided river andis highly susceptibleto channelmigration and avulsion.It is also one of thefew rivers in the worldthat exhibit a tidalbore. It is navigable formost of its length. 11. DRINAGE PATTERN Dendritic Drainage Thedendritic patterndevelops where the riverchannel follows t heslope of the terrain.common in massive rockand in flat lying strata. 12. This pattern looks like treebranches. This patterndevelops in gently slopingbasins with fairly uniformrock type. The tributariesflow into the river at randomforming a pattern like theveins of a leaf. 13. CAUSES OF RIVER POLLUTIONThe growing domestic, municipal, industrial andagricultural demand for water from rivers naturallyaffects the quality of water.As a result more and more water is being drainedout of the rivers reducing their volume.On the other hand, a heavy load of untreatedsewage & industrial effluents are emptied into therivers.This affects not only the quality of water but alsothe self-cleansing capacity of the river. 14. CONSERVATION OF RIVERS. We should not throw the domesticwastes into rivers. We should nottake bath and wash clothes in rivers. Industries should clean thechemical wastes before dischargingit into rivers. We should createawareness among other people.Farmers should use manure insteadof fertilizers because fertilizers areflow away with rainwater into riversand caused great effect to aquaticspecies. 15. WE SHOULD CREATE AWARENESS AMONG OTHER PEOPLE. FARMERSSHOULD USE MANURE INSTEAD OF FERTILIZERS BECAUSEFERTILIZERS FLOW AWAY WITH RAINWATER INTO RIVERS ANDCAUSED GREAT EFFECT TO AQUATIC SPECIES. 16.
