" The Netravati Bridge at Mangalore."
By ARCHIBALD Scott NAPIER, M. Inst. C.E.
THE Netravati River rises in the Western Ghats of India near Ballalrai Droogh in Mysore, and, after crossing the South Canara District, flows into the Arabian Sea close to the town of Mangalore. Its total catchment-area is 1,353 square miles, one-third of which is situated in the Mysore Ghats and two-thirds in the hilly district of South Canara. The maximum rainfall in this area varies between 20 inches in 24 hours on the hills and 11½ inches in 24 hours between the hills and the sea. The Madras Railway crosses the estuary of the river about 2 miles from its mouth, at a point where it is 6,200 feet wide between its banks. The north bank is well defined by the laterite hills on which the town of Mangalore is built, but the southern side is low paddy land, submerged during the rainy season to a depth of 5 to 10 feet, the spill-water extending about 3,000 feet over the land. The range of tides is 4 feet for springs and 2 feet for neaps. Of the 6,200 feet which may be considered to form the river proper, the southern half is much obstructed by sandbanks and islands, the former being submerged at high tide. Only the northern side is used for navigation, and there the channel is well defined and close to the bank, with a depth of 17 feet of water. The river-bed is coarse sand of varying depth, averaging about 20 feet, overlying strata of stiff black and laterite clay on a bottom of gneiss. The surface of this gneiss, which varies in depth from R.L. \emdash 30 on the north side to R.L. \emdash 110 in the middle of the river, is extremely irregular, and is in places overlaid by boulders to a considerable depth, which added . . . . .
