Geomorphic studies conclude that the Brahmaputra, the life-line of Assam is a paleo-river; older than the Himalayas. The river with steep gorges and rapids in Arunachal Pradesh entering Assam, becomes a braided river (at times 10 mi/16 km wide) and with tributaries, creates a flood plain (Brahmaputra Valley: 50-60 mi/80-100 km wide, 600 mi/1000 km long). The hills of Karbi Anglong, North Cachar and those in and close to Guwahati (also Khasi-Garo Hills) now eroded and dissected are originally parts of the South Indian Plateau system. In the south, the Barak originating in the Barail Range (Assam-Nagaland border), flows through the Cachar district with a 25–30 miles (40–50 km) wide valley and enters Bangladesh with the name Surma.
Famous quotes containing the words geography of and/or geography:
“The California fever is not likely to take us off.... There is neither romance nor glory in digging for gold after the manner of the pictures in the geography of diamond washing in Brazil.”
—Rutherford Birchard Hayes (1822–1893)
“The totality of our so-called knowledge or beliefs, from the most casual matters of geography and history to the profoundest laws of atomic physics or even of pure mathematics and logic, is a man-made fabric which impinges on experience only along the edges. Or, to change the figure, total science is like a field of force whose boundary conditions are experience.”
—Willard Van Orman Quine (b. 1908)
