779 words essay on floods in India and its control
Subrat Mangaraj
Countries irrigated by an adequate river system are in many ways blessed. These rivers not only help agriculture, but they provide a cheap and efficient transport system for the development of internal trade.
The saying goes—land divides, seas unite. But waterways bring also a good deal of misery to the people by causing devastating seasonal floods In India, for example, the sub-Himalayan regions of Uttar Pradesh, Bihar, Bengal and Assam are heavily flooded by the rivers of the Gengetic basin and the Brahmaputra, almost every rainy season. It brings untold sufferings to the people of these low-lying plains.
Millions are rendered homeless; men and cattle die in large

Floods leave behind on the submerged areas a rich alluvial or silt-deposit, which greatly increases the fertility of the soil. This soil on either side of the Nile owes its fertility to the annual flooding of the area, which submerges large regions, even after the construction of Aswan Dam in Egypt.
Nehru used to say—give unto the river what naturally belongs to her, i.e. homesteads should not be built on riversides or on temporary char lands. That is a sure preventive measure, better than steps to resist after-effects.
Men have tried from the earliest times to build protective embankments against the incidence of floods. Ordinarily these can be made sufficiently strong to resist the usual type of floods. A system of canals to irrigate the low-lying plains affords considerable escape route for the excess water caused by a normal rainfall. But these embankments should have to be maintained properly.
Modern river engineering and hydro-dynamics, however, have led to a fundamental change in the principle. It is now realised that effective control of flood should begin at the source. Flood control, therefore, in these days has moved upstream. This includes the building of adequate reservoirs in the head stream area and the application of the principle of multipurpose river control.
The building of a sufficient number of reservoirs is a long-drawn and costly process. Public sentiment may not take kindly to it; for it
