MAHANADI, or MAHANUDDY (" The See also:Great See also:River ")  , a See also:river of See also:India . It rises in 2o° 10' N., 82° E., 25 M . S. of See also:Raipur See also:town, in the See also:wild mountains of See also:Bastar in the Central Provinces . At first an insignificant stream, taking a northerly direction, it drains the eastern portion of the See also:Chhattisgarh See also:plain, then a little above Seorinarayan it receives the See also:waters which its first See also:great affluent, the Seonath, has collected from the western portion of the plain; thence flowing for some distance due E., its stream is augmented by the drainage of the hills of Uprora, Korba, and the ranges that See also:separate See also:Sambalpur from See also:Chota See also:Nagpur . At Padampur it turns towards the See also:south, and struggling through masses of See also:rock, flows past the town of Sambalpur to Sonpur . From Sonpur it pursues a tortuous course among ridges and rocky crags towards the range of the Eastern See also:Ghats . This See also:mountain See also:line it pierces by a See also:gorge about 40 M. in length, overlooked by See also:forest-clad hills . Since the opening of the See also:Bengal-Nagpur railway, the See also:Mahanadi is little used for See also:navigation . It pours down upon the See also:Orissa See also:delta at Naraj, about 7 M. See also:west of See also:Cuttack town; and after traversing Cuttack See also:district from west to See also:east, and throwing off numerous branches (the Katjori, Paika, Biropa, Chitartala, &c.) it falls into the See also:Bay of Bengal at False Point by several channels . The Mahanadi has an estimated drainage See also:area of 43,800 sq. m., and its rapid flow renders its maximum See also:discharge in See also:time of See also:flood second to that of no other river in India . During unusually high floods 1,5oo,000 cub. ft. of See also:water pour every second through the Naraj gorge, one-See also:half of which, uncontrolled by the elaborate embankments, and heavily laden with silt, pours over the delta, filling the swamps, inundating the See also:rice-See also:fields, and converting the plains into a See also:sea . In the dry See also:weather the discharge of the Mahanadi dwindles to 1125 cub. ft. per second .

Efforts have been made to See also:

husband and utilize the vast water See also:supply thrown upon the Orissa delta during seasons of flood . Each of the three branches into which the See also:parent stream splits at the delta See also:head is regulated by a See also:weir . Of the four canals which See also:form the Orissa See also:irrigation See also:system, two take off from the Biropa weir, and one, with its See also:branch, from the Mahanadi weir . On the 31st of See also:December 1868 the See also:government took over the whole See also:canal See also:works from the East See also:Indian Irrigation See also:Company, at a cost of 1941,368 . The canals thus taken over and since completed, are the high-level canal, the Kendrapara canal, the Taldanda canal and the Machgaon canal, irrigating 275,000 acres .
